Chinese Company Orders Ultracapacitor Electrode Material

Maxwell Technologies has received a purchase order for 100,000 square meters of its ultracapacitor electrode material from Shanghai Sanjiu Electric Equipment Company. Sanjiu is preparing to introduce a line of ultracapacitor products based on Maxwell's cell architecture and high-performance electrode for the Chinese transportation, electric utility and industrial markets, with a specific focus on Shanghai.

The order is to be filled over the balance of 2007, based on Sanjiu's planned production of 100,000 large-cell 3000-F ultracapacitor cells for the year. It was placed under the terms of an April 2006 ultracapacitor technology license and exclusive electrode material supply agreement between Maxwell and Sanjiu's joint venture parent companies, Shanghai Urban Electric Power Investment Development Corporation (SUEP) and the Ruihua Group. Sanjiu has already produced and delivered a variety of prototype electric and hybrid buses, trucks and other vehicles powered by drive systems employing a combination of batteries and BOOSTCAP ultracapacitors for energy storage and regenerative braking.
