Document Type and Number:
Japanese Patent JP6595348
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a solid electrolyte composition holding high ion conductivity, which enables the materialization of a high binding property e.g. between solid particles or between a solid particle and a current collector; a solid electrolyte sheet for an all-solid type secondary battery, an electrode sheet for an all-solid type secondary battery and an all-solid type secondary battery, each arranged by use of the solid electrolyte composition; and a method for manufacturing a branched polymer.SOLUTION: A solid electrolyte composition comprises: an inorganic solid electrolyte the property of conducting ions of a metal element belonging to Group I or II of the periodic table; and a polymer binder. In the solid electrolyte composition, the polymer binder includes a branched polymer having 3 or more polymer molecule polymerization initiator residue groups at a polymer molecule terminal. Further, a solid electrolyte sheet for an all-solid type secondary battery, an electrode sheet for an all-solid type secondary battery and an all-solid type secondary battery, each arranged by use of the solid electrolyte composition, and a method for manufacturing the branched polymer are disclosed.SELECTED DRAWING: Figure 1
