Abstract

A lithium-iron disulfide electrochemical cell design is disclosed, relying on judicious selection of the electrolyte, a thicker lithium anode and a cathode with specific characteristics selected to cooperate with the electrolyte. The resulting cell has a reduced interfacial surface area between the anode and the cathode but, surprisingly, maintains excellent high drain rate capacity.
