GS Yuasa Corporation, Mitsubishi Corporation (MC) and Mitsubishi Motors Corporation (MMC) officially launched a joint venture—Lithium Energy Japan—to manufacture large-capacity and high-performance lithium-ion batteries. The three companies began collaboration on the project last May. (Earlier post.)
Battery-maker GS Yuasa will be the majority shareholder with 51%; MC will hold 34% and MMC will hold the remaining 15%. Initial production is targeted at 200,000 cells in fiscal year 2009.
The basic cell is the LEV50—based on GS Yuasa’s LIM series of Li-ion batteries, but with modifications in cell-structure and electrode materials to deliver improved energy and power densities.
The LEV50 is a 3.7V, 50Ah cell that weighs 1.7 kg and has a volume of .85L, yielding a nominal 109 Wh/kg or 218 Wh/L. The basic module is the four-cell LEV50-4.
