<p>A rechargeable metal halide battery, in which a salt of an electroplatable metal and a halogen selected from the class consisting of chlorine, bromine and iodine is electrolyzed from solution in a liquid medium during the charging cycle and reformed during the discharging cycle, the battery comprising at least one electrode for making an external electrical connection to the battery, adapted to be immersed in the liquid medium, and a total interface resistance, per square inch of the extended surface, not greater than about 0.10 ohm, the electrode comprising a conductive layer including an electroconductive carbon mass, the mass having a polymeric reinforcing agent in intimate contact therewith to render the mass stable to the liquid medium, the polymeric reinforcing agent being substantially inert to halogen in concentrations present in the battery, and the conductive layer being at least coextensive with the extended electrolyte-contacting surface and having a resistivity, rho , not greater than (0.10xd)/l2 ohm-in., where d is the thickness of the conducting layer and l is the longest electrical flow path through the conductive layer from the liquid medium.</p> |
