摘要： A method for treating a cathode electrode assembly. The method includes providing an electrode including iron disulfide and contacting the electrode with water to remove impurities from the electrode. The electrode may then be dried under various conditions. The moisture content of the electrode after drying may be less than about 600 ppm.

摘要： A primary cell having an anode comprising lithium or lithium alloy and a cathode comprising iron disulfide (FeS2), iron sulfide (FeS) and carbon particles. The electrolyte comprises a lithium salt dissolved in a solvent mixture. A cathode slurry is prepared comprising iron disulfide (FeS2) powder, iron sulfide (FeS) 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.
