Silver oxide electrodes
First Claim
5. THAT METHOD OF MAKING A SILVER OXIDE ELECTRODE COMPRISING THE STEPS OF APPLYING A FIRST SLURRY OF SILVER OXIDE TO A POROUS SUPPORT WHILE APPLYING VACUUM THERETO TO WITHDRAW LIQUID THEREFROM AND FROM A SUBSTANTIALLY UNIFORM LAYER OF SILVER OXIDE ON SAID SUPPORT APPLYING AN ELECTRICALLY CONDUCTIVE SCREEN TO THE SURFACE OF SAID LAYER, APPLYING A SECOND SILVER OXIDE SLURRY TO THE EXPOSED SURFACE OF SAID SCREEN WHILE APPLYING VACUUM TO SAID SUPPORT TO WITHDRAW LIQUID FROM THE THUS DEPOSITED SILVER OXIDE AND FORM A SUBSTANTIALLY UNIFORM LAYER OF IT ON SAID SCREEN, SAID FIRST SLURRY CONTAINING FROM ABOUT 0.25 TO 1.5 GRAMS OF SIVER OXIDE PER SQUARE INCH OF SAID SCREEN SURFACE AREA, AND SAID SECOND SLURRY CONTAINING FROM 2.5 TO 4 TIMES AS MUCH SILVER OXIDE BY WEIGHT AS IN SAID SLURRY, APPLYING PRESSURE TO THE DRIED ARTICLE TO REDUCE THE MOISTURE CONTENT AND COMPACT SAID LAYERS, DRYING THE RESULTANT STRUCTURE AT A TEMPERATURE BELOW 100*C., REMOVING SAID POROUS SUPPORT, THEN HEATING IN A MUFFLE TO A TEMPERATURE BELOW THE MELTING POINT OF SILVER TO CONVERT THE SILVER OXIDE TO METALLIC SILVER, AND ANODICALLY OXIDIZING THE SILVER TO SILVER OXIDE IN AN ALKALINE ELECTROLYTE.
