The development of lithium-ion rechargeable battery
Professor, University of Tokyo lithium-ion rechargeable battery on the Development of Social Systems Innovation
Semiconductor Equipment Association of Japan (SEAJ) held on May 21 lectures and seminars in the spring, University of Tokyo Graduate School of Medicine, Professor of the system into a house Tianxiu Ming Chong as "Innovation Management - the challenge of creating" was published a speech. Miyata presented in the speech of its ships were engaged in systems development, "America's Cup" project, and currently engaged in the use of lithium-ion rechargeable battery, "the social system based on rechargeable battery innovation."
On the "social system based on innovative rechargeable battery," Miyata said the city system into lithium-ion rechargeable batteries and plug-in electric cars to make environmental and energy issues have been substantially improved, and introduced as empirical experiments carried out " Okinawa Project Green New Deal "of the summary. And pointed out that Japanese companies in the DRAM and flat-panel TV market competition in the difficult situation, "can not be made lithium-ion rechargeable battery that DRAM and flat-panel TV", only to meet the subcontracting and manufacturing.
However, lithium-ion rechargeable batteries are also beginning to show signs of danger. Miyata said the lithium-ion rechargeable battery, although the difference between the current product, but in 5 to 10 years will become a common commodity. This raises the systematic, high-class requirements, the current foreign consulting firms and other trading companies in Japan have been in strengthening the environmental business, which began eyeing the more remarkable lithium ion rechargeable batteries and electric cars and other technologies. Intends to increase its value to 2 to 3 times the gross margin of 70% to carry out the business. Miyata that "this is not a bad thing, Japanese firms should also be committed to such a business to maintain and expand its own value."
Miyata said the current power generation and supply systems are still like 30 to 40 years ago as simple as a car, in the future, the advent of smart grid, the addition of computers and software, will form the intelligent system. Intelligent Systems and battery combination will make lithium-ion battery to achieve the added value many times, it is very important. Specific methods to build such a system are as follows: (1) the establishment of lithium-ion rechargeable battery for traceability management, leased or re-use system. Lithium-ion battery life of up to 20 years appropriate. (2) The house or building, especially in data centers are still using lead-acid batteries in the future be replaced by lithium-ion rechargeable battery, and take other measures to ease the peak. (3) solar power and wind power combined with the lithium-ion batteries. By storing electricity, the power system a new look. (4) regions and countries to build the system as a unit. Make full use of new energy a new social system for setting policy resources into specific areas of focus, and to contribute to job creation. Besides, the small countries but also to the overseas promotion.
