No. 674: Lithium-ion battery with two times longer life than the existing lithium-ion battery (December 28, 2012)

Eliiy Power, Japan’s leading producer of lithium-ion batteries for industrial purpose, has developed a technology to lengthen the life of a lithium-ion battery by more than two times. By optimizing the composition of battery materials, the company increased the discharge and charge frequency to world’s highest standard of 12,000 times (about 10 years). Currently the maximum frequency is 6,000 times (about 5 years). It has already started mass producing the new lithium-ion batteries

To increase the life of a lithium-ion battery, Eliiy reviewed the composition of lithium iron phosphate used in the electrode successfully prevented the phenomenon that electric current cannot flow easily in the repetition of discharge and charge from occurring. It also developed a technology to increase the safety of a lithium-ion battery. At the same time, it increased the flash ignition temperature to higher than 70 degrees centigrade by changing the kind of electrolyte. The new electrolyte will be adopted in 2013. According to a survey company, the world market of lithium-ion battery for industrial purpose is expected to increase from 800 million yen in 2012 to 20,000 million yen in 2020.
