摘要： A primary electrochemical is disclosed having an anode comprising lithium metal or lithium alloy, a cathode comprising iron disulfide (FeS2) and carbon particles, and electrolyte. The electrolyte has an additive therein desirably an alkylpyrazole or alkylimidazole. The alkylpryrazole preferably comprises 1,3-dimethylpyrazole or 1,3,5-trimethylpyrazole or mixtures thereof and the alkylimidazole preferably comprises 1,2-dimethylimidazole. A preferred electrolyte comprises a lithium salt dissolved in a solvent mixture comprising 1,3-dioxolane and sulfolane and said additive. The cell has the anode and cathode typically in wound configuration with a separator therebetween.

摘要： A primary cell having an anode comprising lithium and a cathode comprising iron disulfide (FeS2) and carbon particles. The electrolyte comprises a lithium salt dissolved in a solvent mixture which contains 1,3-dioxolane and preferably 1,3-dimethyl-2-imidazolidinone. 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 electrolyte comprises a lithium salt dissolved in a nonaqueous solvent mixture which contains a tin iodide (SnI2) additive. 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 electrolyte comprises a lithium salt dissolved in a nonaqueous solvent mixture which contains 1,3-dioxolane and one or more solvents selected from a furan, or alkylfuran, or alkylhydrofuran or tetrahydrofuran, and mixtures thereof. 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.
