China BAK Battery, one of the largest manufacturers of Lithium Ion (Li-ion) battery cells, announced that it has formed a contract manufacturing partnership with A123Systems, a developer of high-power Nano-Phosphate Li-Ion battery technology based on patented nanotechnology licensed from the Massachusetts Institute of Technology (MIT) (earlier post).
China BAK Battery has collaborated with A123Systems since early 2005 at its Shenzhen facilities to design, to develop and to implement an advanced mass-production line to manufacture exclusively the first products for A123Systems.
High-volume production has begun. The cells have been rigorously tested to meet the most stringent Tier 1 OEM quality requirements. A123 high-power batteries will be used in a variety of applications including power tools, medical devices and hybrid electric vehicles.
The A123Systems batteries promise up to 10x longer life, 5x power gains and dramatically faster charge time (more than 90% capacity in five minutes) over conventional high-power battery technology.
China BAK also announced a strategic cooperation agreement with Lenovo. This agreement calls for both companies to jointly contribute and share resources to further product development efforts. The company has been a supplier of Lithium Ion battery cells for Lenovo cell phone applications since August 2005.
