| 20080318128 | Lithium alloy/sulfur batteries - Electrochemical cells including anode compositions that may enhance charge-discharge cycling efficiency and uniformity are presented. In some embodiments, alloys are incorporated into one or more components of an electrochemical cell, which may enhance the performance of the cell. For example, an alloy may be incorporated into an electroactive component of the cell (e.g., electrodes) and may advantageously increase the efficiency of cell performance. Some electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on the surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. In some cases, the efficiency and uniformity of such processes may affect cell performance. The use of materials such as alloys in an electroactive component of the cell have been found to increase the efficiency of such processes and to increase the cycling lifetime of the cell. For example, the use of alloys may reduce the formation of dendrites on the anode surface and/or limit surface development. | 12-25-2008 |
