Publication number: 20040081894Abstract: Disclosed are oxidizer-treated lithium electrodes, battery cells containing such oxidizer-treated lithium electrodes, battery cell electrolytes containing oxidizing additives, and methods of treating lithium electrodes with oxidizing agents and battery cells containing such oxidizer-treated lithium electrodes. Battery cells containing SO2 as an electrolyte additive in accordance with the present invention exhibit higher discharge capacities after cell storage over cells not containing SO2. Pre-treating the lithium electrode with SO2 gas prior to battery assembly prevented cell polarization. Moreover, the SO2 treatment does not negatively impact sulfur utilization and improves the lithium's electrochemical function as the negative electrode in the battery cell.Type: ApplicationFiled: August 20, 2003Publication date: April 29, 2004Applicant: PolyPlus Battery CompanyInventors: Yevgeniy S. Nimon, May-Ying Chu, Steven J. Visco

Publication number: 20040081895Abstract: The invention provides a battery with improved battery characteristics such as cycle characteristic and storage characteristic. The battery has a rolled electrode body by rolling a cathode and an anode sandwiching a separator in between. The capacity of the anode is expressed by the sum of a capacity component obtained by insertion and extraction of lithium and a capacity component obtained by deposition and dissolution of lithium. The separator is impregnated with an electrolyte solution obtained by dissolving a lithium salt in a solvent. A compound having a B—O bond or P—O bond such as lithium bis [1,2-benzenediolato (2-)-O,O′]borate or lithium tris [1,2-benzenediolato (2-)-O,O′]phosphate is used as a lithium salt. Thus, the formation of a stable film can suppress the decomposition reaction of the solvent and can also prevent the reaction of a deposited lithium metal with the solvent.Type: ApplicationFiled: July 10, 2003Publication date: April 29, 2004Inventors: Momoe Adachi, Shigeru Fujita

Patent number: 6555945Abstract: Actuators are described that operate as a result of double-layer charge injection in electrodes having very high gravimetric surface areas and gravimetric capacitances. The actuator output of the actuators may be a mechanical displacement that can be used to accomplish mechanical work. As a result of the non-faradaic process and the actuator materials utilized, such as carbon nanotubes, the actuators have improved work capacity, power density, cycle life, and force generation capabilities. Other benefits include low voltage operation and high temperature performance. The actuators also convert a mechanical energy input to an electrical energy output. The actuators may be used to control either thermal, electrical or fluid transport or cause either the switching, phase shift, or attenuation of electromagnetic radiation.Type: GrantFiled: August 20, 1999Date of Patent: April 29, 2003Assignee: AlliedSignal Inc.Inventors: Ray H.
