  • High rate, long cycle life electrochemical energy storage devices
    Patent number: 9029015
    Abstract: An electrochemical energy storage device includes a cathode, an anode, and an electrolyte disposed between the cathode and the anode. The anode includes a capacitive material as a majority component, and further includes an electrochemically active material as a minority component, such that an operating potential of the anode is configured according to a reaction potential of the electrochemically active material.
    Type: Grant
    Filed: May 29, 2012
    Date of Patent: May 12, 2015
    Assignee: The Board of Trustees of the Leland Stanford Junior University
    Inventors: Mauro Pasta, Colin Wessells, Robert A. Huggins, Yi Cui
  • High rate, long cycle life battery electrode materials with an open framework structure
    Patent number: 8951673
    Abstract: A battery includes a cathode, an anode, and an aqueous electrolyte disposed between the cathode and the anode and including a cation A. At least one of the cathode and the anode includes an electrode material having an open framework crystal structure into which the cation A is reversibly inserted during operation of the battery. The battery has a reference specific capacity when cycled at a reference rate, and at least 75% of the reference specific capacity is retained when the battery is cycled at 10 times the reference rate.
