  • METHOD OF MAKING AND USING COMPOSITION AND ENERGY STORAGE DEVICE
    Publication number: 20100058578
    Abstract: A method is provided that includes forming brass from zinc powder and copper powder in the presence of a sodium electrolyte. In one aspect, an electrochemical cell is loaded with copper and zinc, the electrochemical cell is heated, and at least one charge/discharge cycle of the electrochemical cell is performed. Alpha brass is converted to gamma brass in presence of zinc and sodium. Methods of producing and operating an energy storage device are also provided.

  • ENERGY STORAGE DEVICE AND SYSTEM
    Publication number: 20100062331
    Abstract: An energy storage device includes a cathodic material having a support structure. The energy storage device has an initial state and a subsequent state. The support structure includes only alpha brass in the initial state, and includes both alpha brass and gamma brass in the subsequent state. An energy storage device includes a cathodic material having an initial state and a subsequent state. In the initial state, the cathodic material includes discrete particles, and in the subsequent state the support structure includes open-cell brass foam. An energy storage system including the energy storage device is also provided.
