Advanced Nickel-Metal Hydride Battery
Phone: (203) 797-2699
Many DOD systems employ rechargeable batteries to supply power. Battery weight, volume, cycle life and cost are generally limited considerations in enabling satisfactory mission performance. Systems presently utilize Lead-Acid, Nickel-Cadmium, Nickel-Metal Hydride or Lithium-Iobatteries. The Nickel-Metal Hydride (Ni-MN) system is now under study as a superior candidate for many applications. Electro Energy, Inc. is presently developing a bipolar version of the Ni-MH system that willyield high energy density (E.D.) of 50-60 Wh/kg, a signifigant improvement above present technologies. In distinction, this proposed projectmore revolutionary than evolutionary, is directed at developing a "next century"version of this system that would yield an E.D. of 85-100 Wh/kg and 300 Wh/l, a 50 to 100% improvement. This will involve the development of both improved hydride materials with significantly greaterhydrogen storage capabilities, improved nickel electrodes, and reducedweight and volume packaging.
