Patent ·
OSTI ID:7100744
A method of incorporating an electrochemically active cadmium compound into a porous, sintered nickel plaque in the preparation of negative plates for nickel--cadmium storage batteries comprises soaking the plaque for at least about 10 minutes in molten Cd(NO/sub 3/)/sub 2/, 4H/sub 2/O which has been heated to boiling at a subatmospheric pressure, removing the plaque and reducing the cadmium nitrate contained herein by heating the plate in a hydrogen-filled container for about /sup 1///sub 2/ hour to about 2 hours at a temperature of from about 200/sup 0/C to about 300/sup 0/C, and allowing the plaque to cool in a hydrogen atmosphere.
