  • Solid polymer electrolyte battery and method for manufacturing positive electrode sheet used therein
    Patent number: 8592090
    Abstract: An organic electrolyte battery (10) including positive electrode material (2) and negative electrode material (4) and, interposed therebetween, organic electrolyte (6), wherein positive electrode active material particles (8) as a constituent of the positive electrode have surfaces at least partially coated with attachment (12) with electronic conductance and ionic conductance not easily oxidized even when supplied with oxygen from the positive electrode active material. The above attachment (12) is composed of microparticles of inorganic solid electrolyte with ionic conductance (14) and microparticles of conductive material with electronic conductance (16).
    Type: Grant
    Filed: May 18, 2005
    Date of Patent: November 26, 2013
    Assignee: Central Research Institute of Electric Power Industry
    Inventors: Hajime Miyashiro, Yo Kobayashi, Shiro Seki, Toru Iwahori
  • Solid Polymer Electrolyte Battery And Method For Manufacturing Positive Electrode Sheet Used Therein
    Publication number: 20080020283
    Abstract: An organic electrolyte battery that through inhibition of any oxidative decomposition of organic electrolyte under high voltage, attains an enhancement of cycle characteristics and is further capable of attaining a realization of high energy density. There is provided organic electrolyte battery (10) comprising positive electrode material (2) and negative electrode material (4) and, interposed therebetween, organic electrolyte (6), wherein positive electrode active material particles (8) as a constituent of the positive electrode have surfaces at least partially coated with attachment (12) with electronic conductance and ionic conductance not easily oxidized even when supplied with oxygen from the positive electrode active material. The above attachment (12) is composed of microparticles of inorganic solid electrolyte with ionic conductance (14) and microparticles of conductive material with electronic conductance (16).
