The joint venture between Hitachi subsidiary Hitachi Maxwell Ltd. and Ube Industries will focus solely on battery separators, handling all aspects, including development, production and sales. Ube Industries will continue to manufacture electrolyte materials for li-ion batteries without assistance from Hitachi. However, Hitachi Maxwell will provide Ube Industries with its microscopic integrated processing technology, which the firm will utilize to produce li-ion separators. Hitachi's long-term goal calls for production of lithium-ion cells to soar to a level that will provide for 700,000 vehicles per year by 2015.
