Patent ID: 8551656

Claim:
A solid electrolyte cell comprising: a positive electrode side layer having a positive electrode active material layer; a negative electrode side layer; and a solid electrolyte layer formed between the positive electrode side layer and the negative electrode side layer, wherein the positive electrode active material layer contains a lithium phosphoric acid compound which is in an amorphous state and is represented by the following formula (1), Li x Cu y PO4 (1) where x indicates the compositional ratio of lithium, and y indicates the compositional ratio of copper, x and y being in the ranges of 1.0≦x≦5.0 and 1.0≦y≦4.0, respectively; wherein the negative electrode side layer includes a negative electrode current collector layer and an oxide-containing layer; and a lithium-containing layer is formed at an interface on the negative electrode side of the solid electrolyte layer at the time of charging.
