TOKYO, JAPAN – July 16, 2009: Nissan Motor Co., Ltd., NEC Corporation, and its subsidiary NEC TOKIN Corporation, today announced that its joint-venture company - Automotive Energy Supply Corporation (AESC) - has begun trial production of advanced lithium-ion batteries for a wide range of automotive applications at its Zama Operations Center.

With start-up capacity at 13,000 units/year, AESC will gradually ramp up production to 65,000 units/year by 2010.

Having twice the energy density of conventional nickel-hydride batteries, AESC's lithium-ion batteries employ a compact module comprised of laminated-type cells, that contribute to more efficient packaging. The use of manganese-type electrode offers thermal stability and the laminated structure improves cooling, thus contributing to the battery's safety performance. The battery has undergone extreme durability tests demonstrating average runs of more than 100,000 km in field tests.

AESC will produce the lithium-ion batteries for Nissan's electric vehicle to be introduced in the U.S. and Japan, as well as Nissan's original hybrid vehicle, in 2010.

AESC intends to mass produce and market its batteries to any interested automaker, with an aim to become a global leader of advanced battery products and services.
