Batteries, storage nickel-metal hydride

The revived interest in electric vehicles, hybrid electric vehicles, and energy storage systems for utilities has accelerated the development of larger-sized rechargeable batteries. Because of the low specific energy of lead-acid batteries and the still unresolved problems with the high temperature batteries, the nickel-metal hydride battery is currently the battery system of choice for hybrid electric vehicles. This subject is covered in another new chapter. Chapter 30 Propulsion and Industrial Nickel-Metal Hydride Batteries. ... [Pg.16]

Hydrogen-storage alloys (18,19) are commercially available from several companies in the United States, Japan, and Europe. A commercial use has been developed in rechargeable nickel—metal hydride batteries which are superior to nickel—cadmium batteries by virtue of improved capacity and elimination of the toxic metal cadmium (see BATTERIES, SECONDARYCELLS-ALKALINe). Other uses are expected to develop in nonpolluting internal combustion engines and fuel cells (qv), heat pumps and refrigerators, and electric utility peak-load shaving. [Pg.300]

High-power lithium-ion batteries are promising alternatives to the nickel metal hydride batteries which are currently used for energy storage in hybrid electric vehicles (HEVs). Currently, Li(Ni,Co)02-based materials are the most widely studied cathode materials for the high-power lithium-ion batteries [1-4]. Although Li(Ni,Co)02-based materials meet the initial power requirement for the HEY application, however, it has been reported that they... [Pg.510]

Energy Conversion Devices (ECD) of Troy, Michigan has announced a potential breakthrough in solid hydrogen storage. ECD is one of the parent companies of GM Ovonics, patent holder for the nickel metal hydride battery. A hydride, by definition, is a solid material that stores hydrogen. [Pg.137]

Those rare-earth AB -type hydrides were quickly utilized in rechargeable nickel metal hydride batteries where electrochemical hydrogen charging and discharging take place at ambient temperature. Such electrochemical hydrogen storage is reversible, when the negative hydride electrode (anode) is combined with the positive Ni electrode (cathode) in the battery cell.. [Pg.14]

As a matter of fact, the first hydrides with practical hydrogen storage capacities were realized in rechargeable nickel metal hydride batteries. For more information on electrochemical hydrogen storage in rechargeable batteries a reader can be referred to several recent reviews on this subject [71-73]. [Pg.14]

Union Carbide showed the possibility of developing D-size hydrogen-nickel batteries with satisfactory performance. However, safety and cost considerations have restricted the applications of such units and the discovery of hydrogen storage alloys led to the development of the nickel-metal hydride secondary cell which was described in Chapter 6.

According to Pearson s Handbook, this crystal structure is commonly known as the CaCus-type structure. The parent LaNis alloy is well known for its unique hydrogen storage properties, and many closely related alloys with the same crystal structure have been commercialized as electrode materials in rechargeable nickel-metal hydride batteries.

Engineering applications such as hydrogen storage in metal hydrides, the nickel-metal hydride rechargeable battery (Ni-MH), and the proton exchange membrane fuel cell (PEMFC) are basically dependent on the surface properties and characteristics. [Pg.132]
