MULTILAYER STRUCTURE FOR ALL-SOLID TYPE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an electrode/electrolyte multilayer structure for an all-solid type battery which enables the achievement of a higher battery capacity.SOLUTION: An electrode/electrolyte multilayer structure for an all-solid type battery is used in a solid type lithium ion secondary battery. (1) The multilayer structure includes a positive electrode layer, a solid electrolytic layer and a negative electrode layer in turn. The multilayer structure further includes an intermediate layer either a)between the positive electrode layer and the solid electrolytic layer or b)between the negative electrode layer and the solid electrolytic layer, or both. (2) The solid electrolytic layer includes a Li-containing oxide having a garnet crystal structure. (3) The intermediate layer includes monoclinic LiMO(where M represents Ti or Mn).
