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] and calcium tetrachloroaluminate [and] is added to the solution to aid the mass transport as well as [the] to lower the freezing point of the electrolyte. In order to eliminate any corrosive effect of the calcium [added] additive to on the lithium anode, this disclosure provides a teaching of the use of an electrolyte solution [and] that is essentially free of any [moist] moisture content.
