NICKEL-HYDROGEN STORAGE BATTERY AND METHOD FOR MANUFACTURE THEREOF

摘要

A nickel-hydrogen storage battery which comprises a positive electrode comprising nickel hydroxide, a negative electrode comprising a metal absorbing alloy, a separator being present between the positive and negative electrodes, and an electrolyte comprising an alkali solution, characterized in that the separator comprises a water absorbing polymer, a water-repellent agent and an aqueous alkali solution. The nickel-hydrogen storage battery has a long cycle life and is reduced in self-discharge, and further can be manufactured at a low cost.
