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. In one embodiment, the surfactant is added after the electrolyte.

Method of manufacturing anode compositions for use in rechargeable electrochemical cells

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.

Method of manufacture of an anode composition for use in a rechargeable electrochemical cell

Rechargeable galvanic cells are disclosed which comprise a manganese dioxide cathode, a zinc anode and a potassium hydroxide electrolyte wherein the cathode includes additive compounds to increase the cumulative discharge capacity of the cell thereby increasing its cycle life. The additives consist of a) barium or strontium compounds, and mixtures thereof, and b) titanium, lanthanum, yttrium, cerium, zinc, calcium, tin or magnesium compounds, and mixtures thereof.
