The rapid progress of super capacitor technology will replace the lithium-ion battery
So far, the industry agreed that the lithium-ion battery electric cars is still the main way of energy reserves, but now several companies have started to consider using a super capacitor (ultracapacitor) lithium-ion battery products as a good supplementary equipment. Neescap an electronics company in South Korea said Tuesday it will pay $ 9,000,000 to expand its transportation, power systems and consumer electronics products with super capacitor (ultracapacitor) product capacity.
In the U.S., have the ability to design and manufacture of super capacitor electrolyte materials and products, the company needed a GrapheneEnergy, EnerG2 and Ioxus three. Another one EEStor companies by venture firms KleinerPerkinsCaufield & Byers as the background, now that the company had signed with the electric car company Zenn super capacitor supply agreement.
More traditional batteries, super capacitors to store electricity is not much. So rechargeable at home (Plug-in) electric vehicles, such as capacitors and power supply equipment can not be used alone, but together with the fuel cells need to use. On the other hand, super capacitors and diarrhea with rapid release of stored energy capacity. Moreover, this capacitor charging time is very short, only a few seconds or minutes of time can be fully charged, and the performance of multiple charge there will not be reduced.
Capacitance in the current consumer electronics products have been used in digital cameras and other occasions, this need for the flash device instantly provides a large energy input of energy supply. According to the experts said, the super capacitor is the main issues in the future how to increase the types of capacitor voltage, so that it can work in high voltage environments.
According to the company's engineers Ioxus, said super capacitor is a good complement environmentally friendly energy, to make batteries, fuel cells, solar or wind power and other power supply is more perfect. At the same time that the production of materials used in capacitors are also very environmentally friendly, the price some are more easily acceptable.
Super capacitor technology for future development directions:
MIT Computer Electronics Engineers JoelSchindall said that in the next few years, super capacitor energy storage capacity will be a qualitative leap. Supercapacitor current product discharge rate is 10 times that of traditional batteries, and energy storage capacity in the same volume conditions, only 5% of the latter.
He said: "super capacitor charge and discharge operations of certain frequent use of a great occasion, such as brake energy recovery brake system (that is, five sets of F1 shows on CCAV nagging what Coles host system) This capacitor is very easy to use. Of course the current products can not replace the battery mass. "
Over the past five years, Schindall led research team has been studying the super-capacitor energy storage component - porous carbon materials, replacing another carbon nanotube conductive matrix material + energy storage components. To this end they set up earlier this year the FastCap company in order to commercialize the research results.
Schindall said super capacitor energy storage capacity of the final product will reach about 25% of the battery. At present, out of Massachusetts Institute of Technology developed nano-materials, energy storage capacity has reached twice the level of carbon materials. And the next few months, he led research team will also show a 5 times the storage capacity of activated carbon products.
