Abstract:

The purpose of this work is to design and develop a 100 WHlb. sealed molten salt secondary battery for vehicle propulsion. The Sohio battery uses a molten lithium chloride-potassium chloride electrolyte, activatable carbon cathodes containing special additives to increase capacity, and lithium alloy anodes. Research cells have been successfully built and tested but are below optimum design. Actual packaged units using low capacity cathodes have delivered 8 watt-hourslb. in their present state of development. A preliminary design has been completed using high capacity research electrodes which indicates a 100 watt-hourlb. battery is practical if more compact packaging can be achieved and if cycle life of the high capacity cathode can be extended at least tenfold.
