Nickel-metal hydride: ready to serve

With their impressive energy performance, outstanding power capability and long life, nickel-metal hydride (NiMH) batteries are equally suitable for use in pure and hybrid electric vehicles. The batteries can deliver and accept charge at very high rates for short periods and boast of a simple hydrogen-transfer mechanism. Significant performance improvements are still under way, yet NiMH batteries already exceed the mid-term performance goals of the US Advanced Battery Consortium. To top things off, NiMH batteries are environmentally friendly and can be totally and profitably recycled.
