Menard, C

A cadmium electrode for a rechargeable alkaline cell comprises a rigid substrate having particle-receiving recesses therein into and upon which are pressed a particulate mix of binder coated cadmium oxide particles and cadmium particles which constitute an active precharge anti-fading constituent of the mix. The binder coating may be a substantially insulating material, in which case the cadmium particles in various places are pressed into the substrate so that they penetrate through the binder coating to make direct contact with the cadmium oxide particles. The binder is most advantageously a curable butadiene polymer binder coating on the cadmium oxide particles preferably formed by heating an initial slurry of an emulsion of the binder and cadmium oxide particles to vaporize the liquid carrier and at least partially cure the binder material.
