• In 1999, GM EV1 equipped with NiMH battery demonstrated a

range of 180 miles between charges.

• Since then, battery cost structure, power performance, and cycle

life have been substantially improved, but the range has not.

• High capacity anode materials are developed but sensitive to

electrolyte corrosion.

• Therefore, continuing research in innovative electrolyte, high-

voltage cathode, and high-capacity anode in NiMH is conduct in the program.
