  • SURFACE MODIFICATION OF BATTERY MATERIALS AND METHOD FOR MAKING A BATTERY
    Publication number: 20130232772
    Abstract: Provided herein are methods for processing electrochemically active materials for use in rechargeable batteries. The methods may also be practiced on electrodes and batteries containing such electrochemically active materials. In a typical embodiment, a method of chemically modifying the surface of an electrochemically active component of a battery is provided, the method including receiving the electrochemically active material and exposing the electrochemically active material to a gaseous reactant under conditions that chemically modify surfaces of the electrochemically active material that are accessible to the gaseous reactant, and thereby produce a modified electrochemically active material having improved properties for use in the battery.

  • CELL ASSEMBLIES WITH NEUTRAL CASES
    Publication number: 20130236757
    Abstract: Provided are electrochemical cell assemblies and methods of fabricating thereof. A cell assembly includes an anode containing lithium titanium oxide and a cathode forming a jellyroll together with the anode. Each of the electrodes is connected to a separate cap and electrically insulated from the case. As such, the case is electrochemically neutral and may be made from a larger selection of materials. For example, a case may be made from steel that would otherwise dissolve if exposed to the anode potential during cycling of the battery. Some of these case materials simplify processing and sealing characteristics. In certain embodiments, a case may be crimped around each of the caps and corresponding gaskets to provide sealing interfaces. The caps or at least their surfaces exposed to the electrolyte are made from materials that are electrochemically stable at corresponding potentials of the electrodes.
