    摘要： A method of forming calcium zincate powder and an electrode from such powder comprises mixing together solutions of a soluble zinc salt and a soluble calcium salt, adding alkaline material to the mixed solution, and precipitating the calcium zincate. The liquid is decanted and the precipitate dried to provide a powder of calcium zincate with impurities of calcium hydroxide and zinc oxide. The powder contacted with a liquid, applied to a support or compacted under pressure to a particular configuration, and the powder is then dried to provide an electrode structure. Soluble zinc and calcium salts which may be employed in the method of the present invention include zinc acetate, zinc nitrate, zinc bromide, zinc chlorate, zinc perchlorate and zinc chloride, calcium acetate, calcium nitrate, calcium bromide, calcium chlorate, calcium perchlorate, calcium chloride, etc.

    摘要： A METAL-AIR CELL HAS AT LEAST ONE CATHODE ELECTRODE, AT LEAST ONE PRECIPITATE-PRODUCING ANODE ELECTRODE SPACED FROM THE CATHODE ELECTRODE, AND AN ABSORBENT ELECTROLYTE MATRIX POSITIONED BETWEEN AND IN CONTACT WITH THE ELECTORDES, THE MATRIX EXTENDING BEYOND ONE OF THE EDGES OF THE RESPECTIVE ELECTRODES AND ADAPTED TO CONTACT A SEPARATE ELECTROLYTE SOURCE. THIS CELL PROVIDES A STRUCTURE IN WHICH A SELF-CLEANING ANODE IS PRODUCED BY THE EMPLOYMENT OF THE EXTENDED MATRIX AND SEPARATE ELECTROLYTE SORUCE.

    摘要： A METHOD OF GENERATING ELECTRICAL ENERGY FROM A BATTERY IS DISCLOSED WHICH BATTERY HAS A CATHODE AND AN ANODE SPACED APART WITHIN A CASING AN ENCAPSULATED AQUEOUS ELECTROLYTE WITHIN THE CASING, AND A SMALL AMOUNT OF ADDITIONAL FREE ELECTROLYTE. UPON INTITIAL CELL DISCHARGE, THE EXPANSION OF THE ANODE RUPTURES THE ENCAPSULATED ELECTROLYTE FURNISHING A SUFFICIENT SUPPLY OF AQUEOUS ELECTROLYTE FOR THE REMAINDER OF THE CELL DISCHARGE. LOSS OF CAPACITY FROM SELF-DISCHARGE IS ELIMATED OR REDUCED TO A NORMINAL AMOUNT SINCE ONLY A SMALL AMOUNT OF ADDITIONAL FREE ELECTROLYTE IS PRESENT IN THE CELL UNTIL CELL DISCHARGE.

    摘要： A SILVER OXIDE-ZINC PRIMARY CELL IS DISCLOSED WHICH COMPRISES A CASING, A ZINC ANODE POSITIONED IN THE CASING, A SEPARATOR ON EACH SIDE OF THE ANODE, A SILVER OXIDE CATHODE ON EACH SIDE OF THE ANODE ADJACENT EACH SEPARATOR AND SPACED FROM THE ANODE, AND MAGNESIUM OXIDE POWDER CONTAINED WITHIN THE CELL. A METHOD IS DISCLOSED FOR ACTIVATING SUCH A CELL WHICH DOES NOT CONTAIN THE MAGNESIUM OXIDE POWDER WHICH COMPRISES MIXING TOGETHER 5 TO 40 WEIGHT PERCENT OF MAGNESIUM OXIDE POWDER IN AN AQUEOUS ALKALINE ELECTROLYTE THEREBY FORMING A POURABLE ELECTROLYTIC SOLUTION, FILLING THE ASSEMBLED CELL WITH THE ELECTROLYTIC SOLUTION, AND ALLOWING THE VISCOSITY OF THE SOLUTION TO INCREASE PRIOR TO DISCHARGING THE CELL. A METHOD IS ALSO DISCLOSED FOR FORMING SUCH A CELL WHEREIN MAGNESIUM OXIDE POWDER IS ADDED TO THE CELL DURING ASSEMBLY, AND THE ASSEMBLED CELL IS FILLED WITH AN AQUEOUS ALKALINE ELECTROLYTE PRIOR TO USE. IN BOTH OF THESE METHODS UPON ACTIVATION OF THE PREVIOUSLY ASSEMBLED CELL, A HIGH VISCOSITY ELECTROLYTIC SOLUTION RESULTS THEREBY PREVENTING SILVER MIGRATION TO THE ANODE AND OTHER CELL COMPONENTS.
