20090111022 | ELECTRODE COMPOSITIONS AND METHODS - Provided is an electrode composition comprising an active material that includes cobalt, tin, and carbon along with methods of making and using the same. Also provided are electrodes that include the provided electrode compositions, electrochemical cells that include the provided electrodes, and battery packs that include at least one of the provided electrochemical cells. In some embodiments, the composition also includes iron. | 04-30-2009 |
20090286162 | REDOX SHUTTLES FOR HIGH VOLTAGE CATHODES - Overcharge protection is provided for rechargeable electrochemical lithium-ion cells. The electrolyte in the provided cells contains a cyclable redox shuttle molecule that can operate in cells with high voltage cathode materials. | 11-19-2009 |
20100050583 | AMMONIA-FREE GASEOUS AIR FILTER - A filter for removing contaminants from air. The filter includes (a) a substrate that does not have any volatile ammonia on the surface thereof; (b) copper that has been impregnated onto the substrate; and (c) molybdenum and/or tungsten that has been impregnated onto the substrate. The filter can be made using an aqueous solution(s) that contains one or more of a first copper salt and a second salt that include a polynuclear anion that contains molybdenum, tungsten, or both. Because the metals can be impregnated onto the substrate surface without using an ammonium-based solution, the need to manage ammonia off-gassing is avoided. Further, no volatile ammonia would be present on the resulting substrate surface. | 03-04-2010 |
20110049418 | CATHODE COMPOSITIONS FOR LITHIUM-ION ELECTROCHEMICAL CELLS - Compositions useful for cathodes in lithium-ion batteries are described.
