    摘要： A primary cell having an anode comprising lithium or lithium alloy and a cathode comprising iron disulfide (FeS2) and carbon particles. The electrolyte comprises a lithium salt preferably lithium iodide (LiI) dissolved in an organic solvent mixture. The solvent mixture preferably comprises dioxolane, dimethoxyethane and sulfolane. The electrolyte typically contains between about 100 and 2000 parts by weight water per million parts by weight (ppm) electrolyte therein. A cathode slurry is prepared comprising iron disulfide powder, carbon, binder, and a liquid solvent. The mixture is coated onto a conductive substrate and solvent evaporated leaving a dry cathode coating on the substrate. The anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added.

    摘要： A primary cell having an anode comprising lithium and a cathode comprising iron disulfide (FeS2) and carbon particles. The cell can be in the configuration of a coin cell or the anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added. The electrolyte comprises a lithium salt dissolved in a nonaqueous solvent mixture which may include an organic cyclic carbonate such as ethylene carbonate and propylene carbon. The cell after assembly is subjected to a two step preconditioning (predischarge) protocol involving at least two distinct discharge steps having at lease one cycle of pulsed current drain in each step and at least one rest period (step rest) between said two steps, wherein said step rest period is carried out for a period of time at above ambient temperature. The preconditioning improves cell performance.
