Abstract: An improved battery cell current collectors which are formed as a unitary structure with mating electrodes attached on one surface. The current collectors are formed of non-metallic material including particle-dispersed plastic tape, plastic dispersed carbon tape, fiber dispersed conductive plastic and carbon tape, or particle and metallic powder dispersed conductive tape to resist corrosion. The need to charge the battery immediately after manufacture is eliminated by the improved battery cell design. Additional utility is provided by fire retardant being mixed with one or both of the electrode composite forming the current collectors and the layer forming the current collectors and by the biasing of the current collectors against their terminating contacts by the compressed current collector material communicating a bias of the current collectors against the internal surface of the battery container thereby increasing current flow and decreasing corrosion.

Abstract: An improved plastic mold for the polymerization of electrophoresis gels. The improved electrophoresis gel mold comprises non-conductive plastic film. The film is supported by a rigid plastic frame. The frame maintains the integrity of the electrophoresis gel. The molds of the present invention are particularly useful in the manufacture of precast electrophoresis gels.
