  • Lithium cell with cathode including iron disulfide and iron sulfide
    Patent number: 8076028
    Abstract: 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.
    Type: Grant
