Abstract
Method of making a flexible metal halide, specifically CuCl.sub.2, positive electrode for a lithium/sulfur dioxide rechargeable electrochemical cell. CuCl.sub.2 is mixed with graphite and a binder such as TFE. Methylene chloride or 1,1,2 trichlorotrifluoroethane is added to form a slurry. The slurry is pasted onto an inert, electrically-conductive, screen-like substrate. The slurry is dried and then heated to cure the TFE. The resulting electrode structure is pressed between rollers to reduce its thickness.
