Requirements for a high energy density, high power density electrochemical energy conversion device have led to the study of a lithium‐chlorine battery. The system operates at 650°C using molten electrolyte. Several cells have been assembled and measurements of the open‐circuit voltage, electrode polarization and coulombic efficiency are reported. The chlorine electrode, made of porous carbon or graphite, was found to be the main source of polarization. Limiting currents were determined and these have been compared with theoretical estimates based on a model for the porous electrode. The model differs fundamentally from those used with aqueous electrolytes since fused does not wet graphite, and hence little or no penetration of electrolyte into the pores occurs.
