Lead Fluoride
An electrochemical cell comprising a lead (II) fluoride cathode, a conductive electrolyte solution such as sea water or a salt-containing organic solvent and an anode of a substance more electropositive than lead fluoride such as magnesium. The cathode preferably comprises lead fluoride, optionally containing an organic binder, a fibrous reinforcement, or a "dope," and an electrically conductive, ionically permeable collector in contact therewith. The cathode may be formed by pressing lead fluoride into a desired shape and then applying metallic collector material onto the cathode surface. Alternatively, molten depolarizing material may be absorbed into a porous graphite collector element and then cooled to form a carbon-reinforced cathode.
