Abstract: An objective of the present invention is to provide an all-solid-state battery with a high discharge capacity in which lithium vanadium phosphate is used as a positive electrode active material layer and a negative electrode active material layer. According to the present invention, the positive electrode active material layer and the negative electrode active material layer of the all-solid-state battery having an all-solid-state electrolyte between a pair of electrodes contain the lithium vanadium phosphate, the lithium vanadium phosphate contains a polyphosphate compound containing Li and V, and the lithium vanadium phosphate contains Li3V2(PO4)3 as a main phase and contains 1.0% by weight or more and 15.0% by weight or less of Li3PO4 relative to Li3V2(PO4)3, whereby a high discharge capacity can be provided.

Abstract: A garnet-type Li-ion conductive oxide containing LixLa3Zr2O12 (6≦x≦8) contains Al and element T (T is one or more from Ni, Cu, Co, and Fe). The content of Al is, in terms of Al2O3, 2.5 mol %≦Al2O3≦15 mol % with respect to a total amount of LixLa3Zr2O12 contained in the garnet-type Li-ion conductive oxide. The content of element T is 25 mol %≦T≦100 mol % with respect to the total amount of LixLa3Zr2O12 contained in the garnet-type Li-ion conductive oxide.
