  • Method of manufacturing anode compositions for use in rechargeable electrochemical cells
    Patent number: 7169508
    Abstract: 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.
    Type: Grant
