A sealed, secondary fused salt battery has been developed which has promise as a battery for electric automobiles. The battery uses active carbon plate cathodes, solid aluminum-lithium alloy anodes, and a fused lithium chloride-potassium chloride electrolyte. Cathode capacity is enhanced by the chemisorption of electrochemically active additives onto the carbon surface. The battery operates between 662 and 932 F.The best energy density achieved to date on a cell is 37.6 w-hr/lb. An improved carbon cathode being developed should enable an energy density of 70 w-hr/lb to be achieved. Insulation bus bars and internal heating coils are expected to add 15% to the weight of the battery.A five-cell battery of sub-optimum design has operated satisfactorily for short cycles. Parasitic leakage currents of less than 0.3% energy loss per hour have been demonstrated. Cycle life of over 1000 has been attained on electrodes.
