  • Patent number: 9406932
    Abstract: In at least one embodiment, a lithium-ion battery is provided comprising a positive electrode, a negative electrode, an electrolyte, and a separator situated between the electrodes. At least one of the electrodes may include a proton absorbing material. The proton absorbing material may be an atomic intermetallic material including a proton absorbed state. The proton absorbing material may react with protons in the electrolyte to reduce moisture formation and cathode degradation in the battery. The proton absorbing material may absorb at least 0.5 wt. % hydrogen and may be present in the anode and/or cathode in an amount from 0.01 to 5 wt. %.

  • Patent number: 9358899
    Abstract: A hybrid or electric vehicle includes a lithium-ion battery and a controller. The controller is programmed to discharge the battery through an electrical load to a predetermined voltage less than a voltage associated with zero state of charge such that relative degrees of lithiation associated with the electrodes of the battery change for at least one state of charge resulting in an increase in battery maximum capacity. The controller may be on-board or off-board of the vehicle. The electrical load may be part of the vehicle or external to the vehicle.

  • Publication number: 20160111727
    Abstract: A metal-ion battery includes an anode assembly and a cathode assembly ionically coupled by an electrolyte. The anode assembly includes a current collector and an anode material capable of intercalation of metal-ions. When the battery is at rest, ionic transfer between the anode and cathode at a minimum and the anode assembly potential with respect to the electrolyte may increase. The increased potential may exceed the reduction potential of the current collector material causing ions to erode from the current collector and contaminate the cathode. The use of a metal, metal alloy or metal compound reduces the rest potential and erosion of the current collector. For example, a lithium foil physically in contact with a copper current collector in a lithium-ion battery reduces the overall anode potential thereby reducing copper dissolution.
