ABSTRACT:
The lithium/carbon/SO.sub.2 energy cell is disclosed wherein the electrolyte includes lithium tetrachloroaluminate. In order to increase the electrical capacity of the cell, the concentration of lithium tetrachloroaluminate in the electrolyte is increased to calcium tetrachloroaluminate and added to the solution to aid the mass transport as well as the lower freezing point of the electrolyte. In order to eliminate any corrosive effect of the calcium added to on the lithium anode, this disclosure provides a teaching of the use of an electrolyte solution and is essentially free of any moist content.
