Mitsubishi i-MiEV Electric Car

Mitsubishi i-MiEV Electric Car

The Japanese carmaker Mitsubishi wants to introduce the world to be i-MiEV electric car now and not only in Japan. This had the car manufacturers on the New York Auto Show and announced in July this year, the electric vehicle in the Japanese car market will be available. The U.S. energy company, Portland General Electric and the U.S. state of Oregon also participates in an extensive test program of the Mitsubishi i-MiEV. As part of the testing program, charging stations for electric vehicles will be built.

The electric car from Japan with the unusual name of a range of 130 kilometers. As a basis, the Mitsubishi minicar "i" made and installed instead of a gasoline motor, a lithium-ion battery, electric motor and charging system. If the battery is empty, it may be at a 220 V electrical outlet within six to eight hours refilled with electricity. The buyer will receive with the purchase of the Mitsubishi i-MiEV a quick-charging plug with which the electric vehicle is recharged within a half hour to 80 percent.

Car manufacturers are increasingly relying on the development of electric cars and reacting to the demand for environmentally friendly vehicles. The economic crisis has hit especially hard the auto companies that have set on cars with high fuel consumption. The U.S. car manufacturer General Motors has failed because of its strong policy model already close to bankruptcy and has been proposed by the U.S. government go bankrupt.

MH-Ni battery as a green pollution-free, maintenance-free, safe, high specific energy and specific power, high-rate charge and discharge performance, long cycle life characteristics of a power source for electric vehicle ideal for [1 3], but the battery at a relatively high temperature conditions often need to work in the development time the need to further improve the MH-Ni battery high temperature performance, in which the key is to improve the cathode of the high temperature performance, because the battery capacity is restricted by the cathode, while the positive charge late in the existence of OH-oxidation reaction of O2, while the oxygen precipitation in the negative on the compound and released a lot of heat, to promote the battery temperature, reducing the cathode active material utilization. solutions are: 1) the battery externally forced cooling; 2) to study the chemical composition of active materials, grain degree of structural defects and surface activity; 3) Select positive additives, such as adding a certain amount of rare earth oxides, Ca2 +, or TiO2, etc. [4 ~ 6].

This choice of transition element yttrium (Y) and rare earth element cerium (Ce) after deposition by chemical additives, added to the nickel electrode active material, and the use of constant current charge-discharge and cyclic voltammetry study of their electrochemical properties of high temperature on the battery effects.

1 experiments

1.1 Ni electrode and the preparation of MH-Ni battery

The measurement of good Y and Ce nitrate solution mixed according to the molar ratio of 1:1 by drops added to the KOH solution, obtained with additive mixture of Y and Ce. Then prepared additives (3%) plus zinc and Cover Nickel Cobalt Hydroxide (97%) and moderate mixed adhesive to the nickel foam after filling the matrix, obtained after roll of nickel electrode. to the positive electrode and hydrogen storage alloy negative electrode and the cell membrane involved in the C-type steel , into the electrolyte, sealing, obtained by room temperature into MH-Ni battery, the nickel electrode containing additives and MH-Ni battery electrodes were marked as B and B cells, the nickel electrodes without additive and MH-Ni battery electrodes were marked as A and A battery for comparison experiments.

1.2 nickel electrode electrochemical and MH-Ni battery charge and discharge test

Nickel electrode as working electrode, Hg / HgO electrode as reference electrode, volume large enough for secondary storage alloy negative electrode, 6mol/dm3KOH solution as electrolyte, electrochemical test instrument in solartron1280B on 25 C and 55 C nickel electrode under 0 25mV / s scan speed cyclic voltammetry. on the A, B cell as room temperature and high temperature 1C charge-discharge (100% DOD) experiments, analysis of additives on the nickel electrode and the MH- Ni battery at high temperature electrochemical properties.

2 Results and discussion

2.1 Ni (OH) 2 structure analysis

Figure 1 (a), (b) respectively after 50 cycles is given after the non-Y and Ce additives Ni (OH) 2 and containing additives, Ni (OH) 2 in the XRD diagram, can be seen from the Figure 1 Both Ni (OH) 2 structure are identical, all B-type, indicating the additive did not change after the Ni (OH) 2 in the crystal.

2.2 1C temperature properties of two cell

MH-Ni battery in the process, the nickel electrode electrochemical reaction between normal

Ni (OH) 2 + OH--> NiOOH + H2O + e-. (1)

When the MH-Ni battery charging late and over-charging, the nickel electrode for the electrochemical reaction occurs

4OH--> 2H2O + O2 |^ +4 e-. (2)

Reaction (1) is expected, while reaction (2) is needed to be suppressed. A, B cell at room temperature (25 C) and high temperature (55 C) next to 1C charge-discharge curve shown in Figure 2,3 shows, the discharge performance parameters listed in Table 1,2. from Figure 2,3 and Table 1,2 shows that when the charge and discharge at 25 C, A, B cells are in charge of a voltage when the late jump, a second voltage level that oxygen evolution platform, two battery discharge capacity and coulomb efficiency is very similar to the Coulomb efficiency of the battery MH-Ni battery is defined as the actual discharge capacity and charge capacity ratio, that is, Coulomb efficiency = discharge capacity / charge capacity x 100%, which shows that charge at room temperature, the nickel electrode oxidation reaction and oxygen evolution on a larger potential difference, can there be until the latter part of the oxygen precipitates, hence the higher charge efficiency, this time to improve battery efficiency of additives on the role of little, and, as the additive reduces the conductivity of the cathode active material, resulting in B cell discharge voltage slightly lower than the A battery. but when at 55 C, B cells in the discharge capacity and coulomb efficiency was significantly higher than A batteries, and Figure 2 shows the charging curve, the end of charging, the battery A no apparent oxygen evolution platform, battery B is a more significant platform for analysis of oxygen because oxygen evolution of nickel cathode overpotential and the temperature in the high temperature cathode overpotential of oxygen evolution decreased, making oxygen evolution potential and Ni (OH) 2 oxidation reaction of potential overlap, thus the late charge is always accompanied by oxygen precipitation, the longer the charge, the more intense oxygen evolution reaction, And when the temperature is higher than 40 C, the nickel electrode surface state has changed, making the activation of oxygen evolution point of Ni (IV) distribution has been significantly improved, favorable oxygen evolution reaction [7], while mixed positive additives at high temperature increased oxidation of nickel electrodes and oxygen evolution potential difference between the improved efficiency of the battery charging temperature.

2.3 Ni electrode cyclic voltammetry experiments

Cyclic voltammetry to study the use of additives on the nickel electrode mechanism of high temperature electrochemical performance, Figure 4 (a), (b), respectively A, B electrodes at 25 C and 55 C, the cyclic voltammetry. By the Figure 4 (a) Obviously, the two electrodes significantly at 25 C, the oxidation peak and reduction peak, and the two anode oxidation peak in the region and oxygen evolution peaks are clearly separated, indicating that at 25 C, whether or not containing additives, nickel electrode Ni (OH) 2 oxidation reaction with oxygen were precipitates can be separated. by Figure 4 (b) can see, 55 C under, A, B electrode although there is an evident reduction potential, but in the anode A regional analysis of electrode, the oxidation peak and peak oxygen overlap, while the B electrode Ni (OH) 2 oxidation peak and peak to peak potential of oxygen evolution clearly separated, indicating that 55 C, non-additive nickel electrode Ni (OH) 2, oxidation potential and oxygen evolution potential overlap, that is, on the nickel electrode at a high temperature oxygen evolution overpotential decreased, while mixing additives with the nickel electrode potential drop, an increase of oxidation potential of oxygen evolution potential and the difference to increase the charge efficiency of nickel electrode under high temperature, which is the battery at 25 C and 55 C, 1C charge-discharge performance test results are consistent. In addition, the added Y and Ce compounds at high temperature to improve battery performance The mechanism of cell cycle in the process of change of the valence of further research.

3 Conclusion

At high temperatures, Y and Ce mixture of additives significantly increased the oxidation potential of nickel electrode and the oxygen evolution potential difference, thereby significantly improve the high temperature charge efficiency of nickel electrode, can play a role in improving battery performance.

Own brands kick off target dual-fuel

Own brands kick off target dual-fuel

Beijing Olympic Games is not only a competition between athletes from various countries, "Green Olympics" slogan all the major car companies for new energy vehicles started a competition. Not only to Volkswagen, General Motors and other auto giants, including BYD, FAW, Changan, China and through other domestic auto companies have also come up with their own new energy vehicles, "serve the Olympics to show the brand."

Qi shot dual fuel its own brand

Olympic demonstration of new energy vehicles to run the project 500 new energy vehicles, more than 400 electric venue vehicles are cars, truly represent the future direction of the 55 electric buses, 25 hybrid buses, 75 hybrid cars 20 hydrogen fuel cars, three hydrogen fuel cell buses. However, after the Olympic Games "Olympic demonstration of new energy vehicles running into the embarrassing fate of high cost," indications are that these new energy from our lives is not so close.

Perhaps because of new energy vehicles some distance away from the real life, but rising fuel prices have begun to challenge their owners and prospective owners of the nerve. Own brands on the one hand continue to increase in the new energy development and production efforts, on the other hand have the objective of targeting the more mature now dual fuel - gas mixture. BYD F31.6L dual fuel already on the market for over a year, this year's F3 launched a 1.5L dual fuel; Geely, the vision of freedom from the ship and then to King Kong, each with a corresponding dual-fuel version; Chery Cowin dual fuel version has also appeared in the taxi market; the SUV market as a break from their places of its own brand of natural will not leave this market, the reporter has learned from its dealers, dual-fuel version of the HARP will be listed in the near future; Lifan 520 dual-fuel version is in Sichuan, Chongqing and other markets.

Beginning just dual fuel domestic market

Although dual-fuel products have launched, however, own brand products in dual-fuel capacity, and not much on the release. BYD has benefited from the support of taxi market, the earlier the face of domestic dual fuel market, even so consumers are not always able to mention cars. "Dual fuel F3 you first order, more than 20 days before mentioning cars." Shaanxi benefits through automobile sales company, said a staff member, and now as a private car use of dual-fuel vehicle market has not developed together, they shop also sold in six-70 year.

Mihashi Geely cars in the city's dealers to see the vision of dual-fuel on a conspicuous place at the gate position, while King Kong, free ship dealers, dual-fuel vehicles still are not to shop. The same, this three cars need to book car and then put in a month; news from the staff of Ise Wei Department showed that the current dual-fuel Kiun Xi'an is also the face of the rental market, and also need to scheduled. The dual-fuel version of the Great Wall Hover, the reporter got the information from the dealers is: "will soon be listed."

For dual-fuel vehicles for domestic market conditions, the benefits through a very representative view of staff, "compared to the same paragraph with the configuration of traditional fuel vehicles, dual fuel and you get about 10,000 yuan, which hindered its In the domestic market development. because private cars as taxis are not as likely to have to run hundreds of kilometers a day, and many owners will run for a few years after the transfer, so they will not pay the million . "

There is no advantage in addition to price, the dual-fuel vehicles cost savings is less obvious constraints in the domestic market is a factor. Members of the public to reporters that Mr. Wang by calculating their means: "Taxi 30 liters of fuel calculated by the day, cost about 180 yuan, burning gas, then the same is 30 liters, costs are more than 70 yuan less than 80, the day will Province 100, the effect is obvious. but replaced by private cars to work every day is a day that is two 30 yuan may be the oil money also will be able to replace gas province of 10 yuan a day or so, but I buy a car when such a one-time pay an extra 10 thousand yuan or so, not too cost-effective. "

Dual fuel market yet to be developed

The development of dual-fuel vehicles, there is a problem faced is the supply of filling stations and gas. Because the gas causes the tension, Hainan, Changchun, Urumqi and other places have called for the suspension of the "gas instead of oil." But the news from Xi'an clean fuel vehicles Coordination Leading Group Office of the learned, to the end of December 2007, Xi'an has developed natural gas vehicles 13 929, of which 3,586 natural gas buses, taxis 10343, built 64 CNG filling stations, on compressed natural gas for 600,000 cubic meters. Construction of stations in stable, standard development, from the "2010 Development of natural gas vehicles 24 000, building 85 compressed natural gas filling stations", the new target is not too far.

The development of dual-fuel vehicles in addition to original products, there is one law car gas instead of oil. Xi'an, but allows only buses, taxis to fuel change gas, on the private car has not let go. Therefore, in the home market of Xi'an, the brand's dual-fuel vehicles own promising, because there is no modification of the opponent, the gas supply is also not too difficult. Reporter Jiang Xiaohong

Tips

Open dual-fuel vehicles must be specially trained pilots, but also check for air leaks at two weeks. Very simple to empty drink bottles filled with water and add a few drops of detergent, shake, coated to a car valve, switch, pipe joints, etc., to see whether air bubbles emerge, bubbles emerge on car shows there is leaking gas, should be promptly repaired. In addition, the cylinder is generally the life of 15 years, relevant departments under the oil to gas in the car every two years to conduct an annual inspection of the cylinder, once the cylinders are worn, to be replaced with new bottle before you can continue to use. Therefore, to change the gas in the car, usually through two gate with fixed cylinder, the cylinder and the gate with a layer of cushion between, the role of a protective cylinder. Once the pad is damaged, cylinders will be worn. Therefore, owners should "close watch" pad, once the damage should be promptly replaced.

Global solar cell market before 2012

Global solar cell market before 2012

Fuji announced the economy of the global solar cell market survey. Solar cells in 2007 the market size for the 1 trillion 200.8 billion yen. 2012 is expected to grow at an annual average growth rate of 27% growth in market size in 2012 will reach 3.9 times the 2007 4 trillion 675.1 billion yen. Market in 2007 nearly 9 to crystalline silicon solar cell, but is expected to reduce the use of silicon in the future or do not use the ratio of silicon solar cells will continue to increase. Which is particularly noticeable is that thin-film silicon solar cells, CIGS solar cells and CdTe (cadmium telluride) thin film solar cells.

Thin film silicon solar cell market in 2007 was 57.8 billion yen. 2012 is expected to increase to 9.7 times in 2007, reaching 559.5 billion yen. As thin film solar cells of low prices of raw materials, manufacturing processes less so in the future is expected to significantly reduce costs. Amorphous silicon solar cells currently have high visibility, but the economic forecast Fuji tandem solar cell structure of future growth. The company plans to expand into this area has reached about 100, about 10 to 20 manufacturers have begun production. And in mass production preparation stage of the company, many will soon be mass production. From Japanese manufacturers and overseas manufacturers of the yield ratio is before 2006, a higher proportion of Japanese firms, but in 2007 the output of foreign firms over Japanese companies. In the future as the United States, Germany, China, Taiwan and India companies gradually increase production, Japanese manufacturers at a disadvantage will be a great possibility.

In 2007 the market size of CIGS solar cells to 120 billion yen. At present the major companies involved in this market for the German Würth Solar, the U.S. Global Solar Energy, the United States Nanosolar, Japan, Showa Shell Solar and Honda Soltec so. Mainly supported by the European market demand, orders for the firms in good condition. Some manufacturers have already planned the next 1 to 2 years, the products sold out, so Fuji economic analysis, the output of all firms that the market will continue to expand in the future. 2012 market size will reach 25 in 2007 times - 299.8 billion yen. In the future, even though indium (Indium) shortage alarming, but Fuji economy explained, "is expected to CIGS solar cell manufacturers and vendors will not be caught in indium indium shortage dilemma."

CdTe thin film solar cell market in 2007 was 630 billion yen. Not yet engaged in the production of Japanese solar cell manufacturers, and also of the solar cell is toxic, so are not allowed in Japan. Overseas manufacturers, the U.S. First Solar thriving, expanding production scale. The company's solar cell sales in 2007, the lowest price of solar cells. The company's 2007 production in Germany and the United States, but in the future will also begin production in Malaysia. Because of low manufacturing cost alone is difficult to maintain our edge, so need to achieve economies of scale, while First Solar has developed a positive production plan. As starters, the company also plans to start mass production, the CdTe thin film solar cell market is expected to further expand. Expected size of the market in 2012 will increase 4.2 times in 2007 266 billion yen.

The new fuel cell materials

The new fuel cell materials

Spanish researchers have developed a fuel cell can effectively improve the efficiency of superlattice electrolyte materials than the current solid oxide fuel cell can greatly reduce costs.

Spanish researchers say such superlattice electrolyte (superlatticeelectrolyte) ionic conductivity than conventional fuel cell components increased by almost 1 million times. This new technology has been the U.S. Department of Energy's largest science and energy research laboratories - Oak Ridge National Laboratory accreditation.

DelphiAutomotiveSystems, BMW and Rolls-Royce has announced the development of solid oxide fuel cell program. However, if the vehicle allegedly used in fuel cells such new superlattice electrolyte, the battery can greatly improve efficiency and reduce production costs.

Ionic conductivity of these materials from the molecular structure of model type can see why it has better ionic conductivity. Superlattice Diego because the interface layer there is a large number of ion vacancies, thus allowing more ions to form a channel through the opening.

Superlattice electrolyte

"Spanish researchers can measure the development of their superlattice material ionic conductivity, but no way to explain." Oak Ridge National Laboratory Materials Science & Technology Department MariaVarela said, "We can give images explain the reasons for the enhanced electrical conductivity. Through these images we can clearly see the tension in the crystal and the order of Jie Mianceng Fenzi structure and how they arranged to Ji Lizitigong wider the Chuansongtongdao.

MariaVarela asserted, "I do not know if the use of such fuel cells can superlattice electrolyte efficiency specific number, but I can say with certainty that it will significantly reduce the cost of fuel cells."

Spanish researchers found in two universities in Madrid: Madrid CommScope Princeton University (UniversidadComplutense) and UniversidadPolitcnica.

Solid oxide fuel cell operating temperature requirements than 1,000 ° F, but the new superlattice electrolyte not only has higher permeability - in order to improve the efficiency of fuel cells, also can work in close to room temperature, it reduces its own temperature and not as solid oxide fuel cells need to "warm up" period of time to work.

Solid oxide fuel cell cathode and anode separated by electrolyte, through the solid electrolyte with the number of positively charged oxygen ions and the circuit with a negative charge by the number of electrons are equal. External circuit connected with the fuel cell electrode. Solid electrolyte and by the Ford, Volkswagen, GE, Dupont and other companies are working to develop fuel cell polymer electrolyte membrane used in the same function.

The efficiency of solid oxide fuel cell electrolyte limited capacity to transfer oxygen ions, while the oxygen ions in the solid electrolyte to pass between the atoms. In order to achieve greater efficiency, solid electrolyte fuel cell operating temperature is usually higher than 1,000 ° F.

The new superlattice electrolyte with the internal structure of a wider gap for oxygen ions, without having to transfer from one atom to another atom. So even in room temperature conductivity of the material atom has also been greatly improved.

The new material is zirconium oxide layer and the oxide layer of strontium titanate overlap, these membranous materials oxygen ion permeability increase can be attributed to overlapping layer of the lattice mismatch. Oak Ridge National Laboratory, developers said they use the resolution of about 0.6 Angstrom (spectral line wavelength units), 300KV, Z contrast scanning transmission electron microscope to show that the lattice mismatch and the resulting gap.

Varela said, "We observed that the oxide layer due to lattice mismatch between the large number of oxygen led to the formation of ion channels."

R & D personnel will observe the results to those who want to interact with the new superlattice electrolyte layer development of solid oxide fuel cell R & D team circulated.

Check quality and to promote development, China's first solar cell industry standard introduced

Recently, China's first solar industry standard glass used in building by the National Organization of Standardization Technical Committee held a "solar glass (commonly known as solar glass) industry standard" approved at the meeting.

The standard proposed solar iron content of glass not more than 0.015%, visible light transmittance greater than or equal to 91.5% (or about 3mm thickness), direct solar transmittance greater than or equal to 91.0% (equivalent to the standard thickness of 3mm).

The standard certified by the China Building Material Test Center drafted. Said standard solar glass is used to cover film crystalline silicon solar cells with high projection than glass. It is learned that the solar cell glass, there is no corresponding international standards can reference the relevant domestic and foreign enterprises generally formulate its own corporate standards were merely used for production control, or incoming inspection. Because there is no unified standard, solar glass industry development and standardization severely constrained.

Experts said that the development of standards, will be related to quality control and inspection company an important reference for the glass industry in promoting the development of solar energy will play an active role. In addition, the industry standard will seek to raise to a higher platform, and strive to become the national standard.

During the two sessions, more aware of the Qing Hu in the industrialization of fuel cell engines urgency. In his view, energy security and environmental protection strategies starting to realize innovation of new energy vehicles, the opportunity has come leaps and bounds.

All countries in the developing world production of new energy vehicles. For a long period of time, a variety of new energy technology cars are opportunities for development. The hydrogen fuel cell vehicles is the world recognized the ultimate zero-emission fuel-efficient vehicles technology solutions in the automotive sector, the development of energy saving direction. Hydrogen fuel is a renewable energy from coal gasification, coke, alkali and other chemical industries were purified by-product of hydrogen recovery, with good economy. China should accelerate the development of hydrogen fuel cell vehicle industry, the pace, and walk in the world.

Key breakthroughs in three key materials

Li Qing Hu told reporters that the industrialization of fuel cell technology involves two aspects of fuel cell technology itself, the second form fuel cell materials and components. Fuel cell from the global and China's state industrial development point of view, superior performance, the raw materials industry is the key to the industrialization of fuel cells, but also improve fuel cell performance and lower cost determining factor.

Julio clear analysis of current domestic hydrogen fuel cell engines are dominated by the cost of fuel cell heap, there are three needs to import raw materials, namely, proton exchange membrane, carbon fiber paper and carbon containing platinum catalyst, so the cost of our hydrogen fuel cells more high. However, mass production in future, especially if the localized three types of raw materials, large-scale production, manufacturing costs will be greatly reduced.

The first "three-electrode" in the proton exchange membrane industrialization. The electrode material plays a barrier in the hydrogen fuel mixed with oxygen, the role of oxidant, but it is also the proton hydration free passage of the conductor and insulator electronics can not. In the fuel cell operating conditions, the membrane must have good mechanical strength and electrochemical stability, have a certain moisture content, and a more stable physical size. Currently used proton exchange membrane of DuPont products.

Second is the "triple electrode" in the industrialization of the gas diffusion layer materials. The material in the electrode catalyst layer plays a supporting, stabilizing role of electrode structure, while also providing feedback to the fuel electrode gas Tongdao, electronic channels and drainage channels, the different diffusion layer materials for the electrode structure, manufacturing process and properties also different. Several commonly used. A carbon fiber paper, carbon cloth and nonwoven cloth.

Third, the carbon electrodes containing platinum catalyst industrialization. The catalyst to help accelerate the anode electrode in the fuel into hydrogen and oxygen to help speed up the reduction of two types of cathode catalyst oxidizer. Currently, many units of domestic R & D of carbon in the platinum catalyst containing platinum and the Philippines. And progress in industrialization, but away from the advanced level there are still some gaps.

The three key raw materials, fuel cells are dependent localization of the domestic chemical industry, research institutes or enterprises in innovative research and development. Dr. Hu Liqing expect the chemical industry for the industrialization of fuel cell technology to contribute.
