    • A primary cell having an anode comprising lithium or lithium alloy and a cathode comprising iron disulfide (FeS 2 ) 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 and dimethoxyethane. The electrolyte typically contains between about 100 and 2000 parts by weight water per million parts by weight (ppm) electrolyte therein. The anode may be lithium metal or preferably is a lithium alloy. 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.
    • 具有包含锂或锂合金的阳极和包含二硫化铁(FeS 2)和碳颗粒的阴极的初级电池。 电解质包含溶解在有机溶剂混合物中的锂盐,优选碘化锂(LiI)。 溶剂混合物优选包括二氧戊环和二甲氧基乙烷。 电解液通常含有每百万重量份(ppm)电解质中约100至2000重量份的水。 阳极可以是锂金属,或者优选是锂合金。 制备包含二硫化铁粉末,碳,粘合剂和液体溶剂的阴极浆料。 将混合物涂覆到导电基材上,并蒸发溶剂,在基材上留下干燥的阴极涂层。 阳极和阴极可以用分离器螺旋卷绕并插入电池壳体中,然后加入电解质。

    • 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 (prediscahrge) 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.
    • 具有包含锂的阳极的主电池和包含二硫化铁(FeS 2)和碳颗粒的阴极。 电池可以是钮扣电池的构造,或者阳极和阴极可以用分离器螺旋形地缠绕在电池壳体中,然后加入电解质。 电解质包括溶解在非水溶剂混合物中的锂盐,其可以包括有机环状碳酸酯如碳酸亚乙酯和丙烯碳。 组装后的电池经受两步预处理(预混合)方案,其涉及至少两个不同的放电步骤,其在每个步骤中具有至少一个周期的脉冲电流消耗以及所述两个步骤之间的至少一个休止期(步进休止),其中 所述停止时间在高于环境温度下进行一段时间。 预处理提高了电池性能。
