Energy Efficient Electrodes for Lithium-Ion Hybrid Vehicle Batteries

Johnson Controls-Saft Advanced Power Solutions and Maxwell Technologies, Inc. today announced a development collaboration through which Maxwell will produce lithium-ion battery electrodes for testing and evaluation by Johnson Controls-Saft.

The electrodes for Li-Ion battery applications will incorporate Maxwell's proprietary process successfully demonstrated in ultracapacitor applications. The collaboration will demonstrate optimized performance while reducing energy consumption, solvent recovery and capital investment.

"Our goal is to develop break-through technology on electrode manufacturing to reduce the cost and environmental impact of advanced automotive batteries for hybrid vehicles," said Mary Ann Wright, who leads the Johnson Controls-Saft joint venture and is vice president and general manager of Johnson Controls' hybrid business. "Maxwell has developed a unique manufacturing process that we can leverage through our global leadership in the development and manufacture of lithium-ion automotive batteries."

Through their collaboration, the two companies will evaluate the integration of Maxwell's proprietary electrode process into the mass production of lithium-ion batteries for hybrid vehicles.

"Johnson Controls-Saft is an ideal advanced battery collaborator with which to explore a high-volume application that could create substantial additional value from the patented process Maxwell originally developed to produce carbon powder-based ultracapacitor electrode material," said Maxwell's president and chief executive officer David Schramm.

Johnson Controls-Saft has been at the forefront of research and development to create advanced batteries for hybrid-electric vehicles, with state-of-the-art R&D centers in Milwaukee, Wisconsin and Bordeaux, France; and battery system engineering, testing and integration centers in Milwaukee, Hanover, Germany, and Shanghai, China. In January 2008, the company opened the world's first lithium-ion automotive battery manufacturing facility in Nersac, France. Johnson Controls-Saft is the world leader in supplying our customers complete batteries, from cells to systems, development, testing, manufacturing and assembly.
