Method of manufacturing a polymer-consolidated cadmium electrode for an alkaline storage cell, and an electrode obtained by the method

摘要

A method of manufacturing a polymer-consolidated cadmium electrode for an alkaline storage cell, the method comprising the steps of: mixing the following ingredients in water: a gelling agent; cadmium and cadmium oxide in powder form constituting the active material; and a copolymer of carboxylated styrene-butadiene at a concentration lying in the range 0.5% to 3% by weight of active material; coating the resulting paste on a metal current collector; drying the coated current collector; and subjecting the resulting assembly to a temperature lying in the range 120 DEG C. to 150 DEG C. for a period of a few minutes in order to cause said polymer to cross-link.
