Ultrafine Hydrogen Storage Powders

This invention provides for composition and method of making extremely fine powders for storing hydrogen.
The use of the powders decreases problems that are normally encountered when storage powders repeatedly experience during absorption and then desorption of the hydrogen. In the case of batteries, this repeated expansion and contraction can cause diminished recharge capacity and even inactivity because of fracture of the electrode. These powders have applications in batteries, particularly those composed of nickel/metal hydride; hydrogen absorption refrigerators (cryocoolers); and other devices that incorporate the need to encompass reversible gas phase absorption/desorption of hydrogen.
