Abstract
A high discharge capacity in an all-solid-state battery in which lithium vanadium phosphate is used in a positive electrode active material layer and a negative electrode active material layer. An all-solid-state battery wherein a positive electrode active material layer and a negative electrode active material layer contain lithium vanadium phosphate, which includes a Li- and V-containing polyphosphate compound and satisfies 1.50<Li/V≤2.30, with the percentage of divalent V included in the V being 5˜80%. Thus, a high discharge capacity can be provided.
