Electric vehicle (EV) technology has been limited by the availability of suitable battery technology to provide the required vehicle range and performance at acceptable cost. Ovonic Battery Co. has developed a proprietary nickel metal hydride battery that provides the required advances in battery technology. This technology is based on the application of multi-element, multi-phase hydride alloys developed for use as negative electrode materials. Ovonic batteries have demonstrated high energy and power density, long cycle life, excellent overcharge and overdischarge tolerance, and wide operating temperature range. An overview of cell and battery performance is presented as well as results discussed for EVs powered by Ovonic batteries. 20 refs.
