Performance Study on Zirconia Cloth Separator for High Pressure Ni-H2 Battery
High pressure NiH2 battery is a kind of secondary power consists of a nickel electrode and the hydrogen electrode with the quality of high stability, long service life, overcharge and overdischarge resisting advantages, the United States, Russia and France have launched high pressure NiH2 batteries and has been widely used in satellite, space stations and other areas. Performance of strength, Ability of Antioxidation, Chemical Durability, Dimensional Stability and akali retaition ability were strictly required by NiH2 battery’s seporatosr, zirconia cloth seporator can satisfy the use requirement in many aspects. Physical and chemical properties of areo density, average thickness, alkaline retention ability, alkaline absorbing ratio and battery performance were tested in this paper.
