TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Nitrate Compound: The molten nitrate compound is combined with a nitrate compound.Preferred Lithium Salt: The dissolved lithium salt(s) in the organic compound is selected from lithium hexafluorophosphate, lithium hexafluoroarsenate, lithium chlorate, lithium triflate salts and lithium imide salts.Preferred Anode: The anode is made of a material selected from an lithium-aluminum alloy, an lithium-silicon alloy, a calcium alloy, a magnesium alloy, a zinc alloy, a lithium-boron alloys, and a molten lithium immobilized with a metal selected from nickel, copper and stainless steel felt metal. The lithium-aluminum alloy comprises 20-25 w/w % of lithium. The lithium-silicon alloy comprises 40-55 w/w% of lithium.Preferred Cathode: The cathode is made of a material selected from silver chromate (Ag2CrO4), vanadium pentoxide, lithium cobaltate, lithium nitrogen oxide, complex oxide of lithium, nitrogen and cobalt (LiNixCo1-xO2), chromium dioxide, lithiated chromium oxide, manganese dioxide and lithiated manganese oxide.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Organic Compound: The organic compound containing dissolved lithium salts is an organic compound selected from propylene carbonate, ethylene carbonate, dimethyl sulfone and di-p-tolylsulfone. SPECIFIC COMPOUNDS - The 1-ethyl-3-methylimidazolium salt is selected from 1-ethyl-3-methylimidazolium tetrafluoroborate, 1-ethyl-3-methylimidazolium trifalte and 1-ethyl-3-methylimidazolium mesylate.    EXAMPLE - The performance of lithium silicon/lithium nitrate-potassium nitrate/chromium dioxide cell at 200degreesC and a current density of 15 mA/cm2, was evaluated. The cell was 1.25 inches in diameter, with a 1-g anode and 1-g cathode. The anode was 44% lithium/56% silicon and contained 20% electrolyte and the cathode contained 20% electrolyte as well as 10% KS-6 graphite, as a conductive additive. (Analysis with differential scanning calorimetry showed that the graphite is stable with the molten nitrates under these conditions). The electrolyte composition was 33.6% lithium nitrate/66.94% potassium nitrate. The cell discharged for 5000 s to a cutoff voltage of 1 v and the resistance did not increase dramatically until over 3000 s.
