Nickel–metal hydride battery. A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel-cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of ...
A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar) pressure. [6] The nickel–hydrogen battery was patented in the ...
Stanford Robert Ovshinsky (November 24, 1922 – October 17, 2012) was an American engineer, scientist and inventor who over a span of fifty years was granted well over 400 patents, mostly in the areas of energy and information. [1] Many of his inventions have had wide-ranging applications. Among the most prominent are: the nickel-metal hydride ...
Nickel–metal hydride: 66 300–800 [13] Low self-discharge nickel–metal hydride battery: 500–1,500 [13] Lithium cobalt oxide: 90 500–1,000 Lithium–titanate ...
The 2011 Nissan Leaf had lower range and smaller battery capacity than the 1999 GM EV1. Nevertheless, it was a hit. The 1999 GM EV1 production vehicle, powered by nickel metal hydride batteries, had a 26.4 kWh battery and an EPA range of 105 miles.
[83] [84] The batteries were rated at 60 amp-hours at 312 volts (18.7 kWh), extending the EV1's range to 90 miles (145 km). [85] Shortly after the introduction of the second generation cars, the planned nickel–metal hydride (NiMH) "Ovonics" battery pack, developed under the Delco Remy organization, commenced production.
