SEALED TYPE NICKEL-METAL HYBRIDE ALKALINE STORAGE CELL

摘要

A sealed type nickel-metal hydride storage cell which sustains good cell efficiency during the continuous charge for a long time in a wide range of temperature between low to high is provided. In the sealed type nickel-metal hydride storage cell, a positive electrode mainly comprises nickel active material, and it also comprises either zinc or cadmium or both; a negative electrode mainly comprises a hydrogen absorbing alloy; separator material is made of non-woven fabric of polyolefin resin or polysulfone; and electrolyte is alkaline solution. Also as for the amount of the electrolyte to be poured into the cell, the amount X of the electrolyte held in the separator and the weight Y of the separator material should be 0.3
