Abstract
A method of manufacturing a metal hydride alkaline storage cell includes a first step of preparing a negative electrode by applying a paste containing hydrogen absorbing alloy powder onto a substrate; and a second step of placing the negative electrode and a positive electrode into a cell can with disposing separator therebetween, and thereafter pouring an electrolyte into the cell can. Into the paste or the electrolyte, a catalytic metal compound that has a proportion of 0.1 to 2.5 wt. % based on the weight of the hydrogen-absorbing alloy powder and that is soluble in the electrolyte is added. Consequently, the catalytic action of the metal is fully utilized by this method that dots a catalytic metal or metal compound on the alloy surface, and thereby the inner pressure characteristic (high-rate charge characteristic) of a cell is improved.
