Claims
- 1. A method for improving the rechargeability of an electrochemical cell having an anode, a separator, an electrolyte, and a cathode comprising monovalent silver oxide comprising the steps of admixing with said silver oxide a material selected from the group consisting of mercuric oxide, cadmium oxide, cadmium hydroxide and manganese dioxide; and substantially homogeneously dispersing above about ten percent by weight of the cathode of a metal selected from the group consisting of silver, nickel and a mixture of silver and nickel throughout said cathode; whereby, upon discharging of said cell a stepped decrease in cell voltage occurs and recharging of said said cell can be effected prior to complete discharge of said cathode whereby a matrix of said metal will be maintained in said cathode to improve the rechargeability of said cathode.
- 2. The method of claim 1 wherein said metal comprises silver.
- 3. The method of claim 1 wherein said metal comprises nickel.
- 4. The method of claim 1 wherein said cathode contains said metal in an amount sufficient to improve the rechargeability of said cathode.
- 5. The method of claim 1 wherein said cathode contains said metal in an amount up to about forty percent by weight of the cathode.
- 6. The method of claim 1 wherein said cathode contains said material in an amount of from about twenty percent to about sixty percent by weight of the cathode.
- 7. The method of claim 6 wherein said anode further comprises mercury and zinc oxide.
- 8. The method of claim 1 wherein said anode comprises zinc.
