A123 Systems, the Waltham-based battery maker with operations in Westborough and Hopkinton, says a product made by its co-owned Shanghai-based company will be used in new plug-in hybrid electric sedans made by Chinese automaker Geely.
Under a new agreement, A123 will supply prismatic cells to the joint venture, Advanced Traction Battery Systems, for the production of lithium ion battery packs for the cars. Geely will launch the new cars in China in 2014, A123 said.
