GS Yuasa claims new battery will double electric vehicle range
GS Yuasa will start mass production of lithium-ion batteries that it said will double small electric vehicle (EV) driving ranges by 2020. The batteries will be developed by Lithium Energy Japan, a joint venture between trading house Mitsubishi Corp. and Mitsubishi Motors, and be supplied to car makers in Japan and Europe. The battery would extend the driving range of the Mitsubishi i-MiEV compact from 170 km (106 miles) per charge to some 340 km, comparable to that of a larger car with a bigger battery.
