  • Power supply apparatuses and power supply operational methods
    Patent number: 6809500
    Abstract: Power supply apparatuses and power supply operational methods are provided. According to one aspect, a power supply apparatus includes a power node, an electrochemical device configured to store electrical energy, a switch including a control node and the switch is adapted to electrically couple the electrochemical device with the power node in a conducting state and to substantially electrically isolate the electrochemical device and the power node in a nonconducting state, a controller configured to output a first control signal to control the operation of the switch between the conducting state and the nonconducting state and circuitry coupled with the controller and the control node and configured to receive electrical energy at a first voltage magnitude, to increase the electrical energy to a second voltage magnitude greater than the first voltage magnitude to provide a second control signal, and to output the control signal of the second voltage magnitude to the switch.

  • Preparation of lithium-containing materials
    Patent number: 6702961
    Abstract: The invention provides novel lithium-mixed metal materials which, upon electrochemical interaction, release lithium ions, and are capable of reversibly cycling lithium ions. The invention provides a rechargeable lithium battery which comprises an electrode formed from the novel lithium-mixed metal materials. Methods for making the novel lithium-mixed metal materials and methods for using such lithium-mixed metal materials in electrochemical cells are also provided. The lithium-mixed metal materials comprise lithium and at least one other metal besides lithium. Preferred materials are lithium-mixed metal phosphates which contain lithium and two other metals besides lithium.
