ABSTRACT:
A high voltage electrochemical cell is provided which includes an active metal as anode, such as sodium, a mixture of a transition metal halide or sulfide, e.g. CuCl.sub.2 and graphite as the cathode and an electrolyte of a room temperature chloroaluminate molten salt such as MEIC-AlCl.sub.3 buffered to Lewis acid-base neutrality by an excess of metal halide, such as NaCl, to provide a discharge potential or open-circuit voltage of up to 2.78 V or more. The battery cell of the present invention is believed the first to use sodium as an active metal anode in a room temperature, molten salt electrolyte. The battery cell of the present invention is useful for long-life, low drain applications, e.g. remote sensors and surveillance equipment.
