Abstract
Abstract A primary electrochemical cell comprising a lithium anode, an iodine trichloride cathode, and a non-aqueous electrolyte. The non-aqueous electrolyte preferably comprises thionyl chloride with additives of iodine monochloride, lithium aluminum chloride, or mixtures thereof. Thionyl bromide may be substituted for the thionyl chloride.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
82 words
In a primary electrochemical cell comprising a receptacle containing an anode, a cathode, and a non-aqueous electrolyte, and having means for delivering an electrical current flow therefrom; (a) said anode consisting essentially of lithium; (b) said cathode consisting essentially of iodine trichloride; and (c) said non-aqueous electrolyte selected from the group consisting of thionyl chloride and thionyl bromide, with said electrolyte containing a solute therein, the solute being selected from the group consisting of lithium aluminum chloride, iodine monochloride, and mixtures thereof.
Claim 2
Dependent Claim
