Garnet-type ion conducting oxide, complex, lithium secondary battery, manufacturing method of garnet-type ion conducting oxide and manufacturing method of complex
An all-solid lithium secondary battery 20 includes a solid electrolyte layer 10 composed of a garnet-type oxide, a positive electrode 12 formed on one surface of the solid electrolyte layer 10 and a negative electrode 14 formed on the other surface of the solid electrolyte layer 10. This all-solid lithium secondary battery 20 includes an integrally sintered complex of the solid electrolyte layer 10 and the positive electrode active material layer 12a. 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 Li7+X−Y(La3−x,Ax) (Zr2−Y,TY)O12, 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.
