Development with quasi-bipolar Horizon/sup R/ technology

Abstract

Electrosource Inc. (ELSI) is now in production with an electric vehicle (EV) battery based on fundamental advances in materials design, manufacturing processes and well understood lead-acid electrochemistry. The production 12 V-85 Ah module is rated at 45 Whr/kg, 223 W/kg and 400 C/3 cycles. Production test modules have achieved over 50 Whr/kg and 500 cycles. Chrysler has chosen the Electrosource Horizon Battery for their EV Minivan that will be in production next year. Design flexibility has led to a hybrid electric vehicle battery as well as SLI, UPS and portable power.
