  • Anode balanced lithium—iron disulfide primary cell
    Patent number: 8790828
    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.
    Type: Grant
    Filed: October 31, 2013
    Date of Patent: July 29, 2014
    Assignee: The Gillette Company
    Inventors: Steven Jeffrey Specht, Michael Pozin, Yelena Valentinovna Kouznetsova, Bhupendra Kanchanial Patel, Fred Joseph Berkowitz

  • Electrochemical cells with improved separator and electrolyte
    Patent number: 8349493
    Abstract: An electrochemical cell is described. The electrochemical cell includes an anode, a cathode, a separator between said anode and said cathode, and an electrolyte. The electrolyte includes a salt dissolved in an organic solvent. The separator in combination with the electrolyte has an area specific resistance less than 2 ohm-cm2. The electrochemical cell has an interfacial anode to cathode ratio of less than about 1.1.

  • 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.
