  • Publication number: 20200173028
    Abstract: A copper foil, intended for use as a current collector in a lithium-containing electrode for a lithium-based electrochemical cell, is subjected to a series of chemical oxidation and reduction processing steps to form a field of integral copper wires extending outwardly from the surfaces of the current collector (and from the copper content of the foil) to be coated with a resin-bonded porous layer of particles of active electrode material. The copper wires serve to anchor thicker layers of porous electrode material and enhance liquid electrolyte contact with the electrode particles and the current collector to improve the energy output of the cell and its useful life.

  • Patent number: 10668822
    Abstract: A rotary system includes a rotor, a vector-based position sensor, and a controller executing a method to eliminate fundamental harmonic position measurement error. The sensor measures angular position of the rotor and outputs raw sine and cosine signals representative of the angular position. The raw signals have a fundamental harmonic position measurement error at the frequency of the sensor signals. The controller receives the raw signals, adaptively adds or subtracts sensor signal offsets to or from the raw signals to generate offset sine and cosine signals, calculates a corrected position of the rotor using the offset sine and cosine signals eliminating the fundamental error, and controls an action or state of the rotary system using the corrected position. The rotor may be part of an electric machine, such as in a vehicle.
