Abstract
An electrode (40) for a Ni/MHx storage cell (47) is prepared by providing a substrate (62) and providing an active material in a finely divided form. A paste (60) of a mixture of the active material, optionally a finely divided carbon powder, and a solution of a polymer in an organic solvent is formed. The paste (60) is coated onto the substrate (62). The paste-coated substrate (62) is immersed into water to wash away the organic solvent and to precipitate the polymer, completing the anode fabrication. This electrode (40) is assembled with another electrode (44) and as a separator (46) between the electrodes (40 and 44) and provided with an electrolyte (50), to form the electrochemical cell (47).
