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.

Additives for rechargeable alkaline manganese dioxide cells

A cylindrical electrochemical cell includes a cathode, an anode, a cylindrical separator, coaxial with the cell, for electrically separating the cathode and anode, and a cup seal at an end of the separator for electrically separating the anode and cathode and maintaining an ionic connection therebetween. The cup seal is comprised of one or more first layers of a micro-porous or a non-porous membrane, or a combination thereof, and one or more second layers of a porous membrane and wherein the seal overlaps at least a portion of the separator.
