Abstract
The invention described herein is directed to a method of manufacturing an anode composition for use in an electrochemical cell, in which the anode comprises an electrochemically active material, the method comprising the steps of mixing the electrochemically active material with an alkaline electrolyte solution, an organic surfactant, an indium compound, and a gelling agent, such that the indium compound or a portion thereof is added in an alkaline environment.
Claims24
A rechargeable cell that performs at least twenty-five discharge and charge cycles comprising:
- a cathode having an electrochemically active powder including an oxide of manganese;
- an anode comprising an anode composition, said anode composition comprising an electrochemically active zinc alloy powder, wherein said composition is manufactured by a method comprising the step of mixing said zinc alloy with an alkaline electrolyte solution, an organic surfactant, an indium compound, and a gelling agent, such that said indium compound is added in an alkaline environment and wherein the organic surfactant is added after the alkaline electrolyte;
- a separator including at least one semipermeable membrane;
- and an electrolyte solution in the separator, the cathode and the anode, and filling pores thereof.
