Publication number: 20080099734Abstract: Solid battery components are provided. A block copolymeric electrolyte is non-crosslinked and non-glassy through the entire range of typical battery service temperatures, that is, through the entire range of at least from about 0° C. to about 70° C. The chains of which the copolymer is made each include at least one ionically-conductive block and at least one second block immiscible with the ionically-conductive block. The chains form an amorphous association and are arranged in an ordered nanostructure including a continuous matrix of amorphous ionically-conductive domains and amorphous second domains that are immiscible with the ionically-conductive domains. A compound is provided that has a formula of LixMyNzO2. M and N are each metal atoms or a main group elements, and x, y and z are each numbers from about 0 to about 1. y and z are chosen such that a formal charge on the MyNportion of the compound is (4?x). In certain embodiments, these compounds are used in the cathodes of rechargeable batteries.Type: ApplicationFiled: April 2, 2007Publication date: May 1, 2008Applicant: Massachusetts Institute of TechnologyInventors: Yet-Ming Chiang, Donald R.

Publication number: 20070099084Abstract: A battery electrode comprises an electrically conductive substrate having an electrochemically active electrode composition supported thereupon. The composition includes an active material capable of reversibly alloying with lithium, which material shows a volume change upon such reversible alloying. The composition includes a buffering agent which accommodates the volume change in the active material and minimizes mechanical strain in the composition. The active composition may further include materials such as carbon. The active material may comprise silicon, aluminum, antimony, antimony oxides, bismuth, bismuth oxides, tin, tin oxides, chromium, chromium oxides, tungsten, and tungsten oxides or lithium alloys of the foregoing. The buffering agent may comprise a metal or a metal oxide or lithium alloys of the foregoing. Also disclosed are batteries which incorporate these electrodes, methods for the fabrication of the electrodes and methods for the fabrication and operation of the batteries.Type: ApplicationFiled: October 30, 2006Publication date: May 3, 2007Applicant: T/J Technologies, Inc.Inventors: Biying Huang, Suresh Mani, Jun Chin

Publication number: 20070057228Abstract: A composite electrode material is fabricated from a first electroactive material which, when incorporated into a cathode of a rechargeable battery, manifests a first mean voltage, a first energy density and a first high cutoff voltage cycle life; and a second electroactive material which, when incorporated into a cathode of the rechargeable battery, manifests a second mean voltage which is less than the first mean voltage, a second energy density which is less than the first energy density, and a second high voltage cutoff cycle life which is greater than the first cycle life. The composite material is characterized in that when it is incorporated into a cathode of the rechargeable battery, it manifests at least one of: a third mean voltage which is greater than the second mean voltage, a third energy density which is greater than the second energy density, and a third high cutoff voltage cycle life which is greater than the first cycle life.Type: ApplicationFiled: September 14, 2006Publication date: March 15, 2007Applicant: T/J Technologies, Inc.Inventors: Biying Huang, Suresh Mani, Jun Chin
