  • LAMINATE FOR ALL-SOLID TYPE BATTERY
    Publication number: 20140154586
    Abstract: A laminate for an all-solid type battery which is an electrode/electrolyte laminate used in an all-solid type battery. The laminate includes a positive electrode layer, a solid electrolyte layer and a negative electrode layer in this order, and at least one intermediate layer disposed between (a) the positive electrode layer and the solid electrolyte layer and (b) the negative electrode layer and the solid electrolyte layer. The solid electrolyte layer contains a Li-containing oxide having a garnet crystal structure, and the intermediate layer contains monoclinic Li2MO3, where M represents Ti or Mn.

  • COMPOSITE ELECTRODE MATERIAL AND METHOD OF PRODUCING THE SAME, NEGATIVE ELECTRODE FOR METAL-AIR BATTERY, AND METAL-AIR BATTERY
    Publication number: 20120082922
    Abstract: The present invention relates to a composite electrode material having a carbon base material and iron oxide particles mainly containing Fe3O4 and being supported on the carbon base material and the particles have a D90 of 50 nm or less. In the composite electrode material, since the particle size of the iron oxide particles mainly containing Fe3O4 serving as an active material is small, the electron conductivity of the composite electrode material is not considerably reduced even when being covered with a Fe(OH)2 layer as a reactive intermediate for an electrode reaction. Thus, when the composite electrode material is used, an iron negative electrode having sufficient electron conductivity and charge-discharge cycle characteristics is provided. A negative electrode including the composite electrode material is favorably used as a negative electrode for a metal-air battery.
