Document Type and Number:
Japanese Patent JP5195975
Kind Code:
B2
Abstract:
The present invention provides an all solid state battery for inhibiting interface resistance between a cathode active material and a solid electrolyte material. The invention solves the problem by providing a solid state battery comprising a cathode active material layer, an anode active material layer and a solid electrolyte layer formed between the cathode active material layer and the anode active material layer, wherein at least one said cathode active material layer and solid electrolyte layer contains a sulfide solid electrolyte material, a reaction inhibition portion containing a first ion conductor and a second ion conductor formed on the surface of the cathode active material, the first ion conductor is a lithium compound with ion conductance of 1.0×10−7 S/cm or more at normal temperature, and the second ion conductor is an Li-containing compound with polyanion structural portion having one of B, Si, P, Ti, Zr, Al and W.
