Abstract
An all-solid lithium secondary batteryincludes a solid electrolyte layercomposed of a garnet-type oxide, a positive electrodeformed on one surface of the solid electrolyte layerand a negative electrodeformed on the other surface of the solid electrolyte layer. This all-solid lithium secondary batteryincludes an integrally sintered complex of the solid electrolyte layerand the positive electrode active material layer. This complex is obtained by integrally sintering a stacked structure of an active material layer and a solid electrolyte layer. The solid electrolyte layer includes: abase material mainly including a fundamental composition of Li(La,A) (Zr,T)O, wherein A is one or more of Sr and Ca, T is one or more of Nb and Ta, and 0≦X≦1.0 and 0≦Y<0.75 are satisfied, as a main component; and an additive component including lithium borate and aluminum oxide.
