  • Anode balanced lithium-iron disulfide primary cell
    Patent number: 8617743
    Abstract: A primary electrochemical cell having an anode comprising lithium and a cathode comprising iron disulfide (FeS2) and carbon particles. The cell is balanced so that the anode is in theoretical capacity excess (mAmp-hrs) compared to the theoretical capacity of the cathode. 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 organic solvent.

  • ELECTROCHEMICAL CELLS WITH IMPROVED SPIRAL-WOUND ELECTRODE ASSEMBLY
    Publication number: 20120315523
    Abstract: A spiral-wound electrode assembly, an electrochemical cell with the spiral-wound electrode assembly, and a method of manufacturing an electrochemical cell with the spiral-wound electrode assembly are disclosed. The spiral-wound electrode assembly has a first electrode that has a first electrode active material, a leading edge and a trailing edge. The assembly has a second electrode that includes a second electrode active material, a leading edge and a trailing edge. A separator is located between the first electrode and the second electrode. The electrode assembly has an interfacial anode-to-cathode ratio of less than about 1.2. The first electrode, second electrode, and separator are wound so that the first electrode forms a layer at the outermost radius of the electrode assembly and so that the trailing edge of the second electrode extends past the trailing edge of the first electrode.
