<P>PROBLEM TO BE SOLVED: To provide an all-solid battery which has highly safety as well as high capacity, high power, and long life and uses sodium, which has no possibility of resource desiccation, for cation and can be manufactured inexpensively. <P>SOLUTION: The all-solid battery includes a positive electrode 1 including a positive electrode active material, a negative electrode 2 including a negative electrode active material, and a solid electrolyte layer 3 including a solid electrolyte represented by following general formula (1). At least either of the positive electrode 1 and the negative electrode 2 further includes the solid electrolyte, and at least either of the positive electrode active material and the negative electrode active material is a material represented by following general formula (2). General formula (1): Na<SB>1+y</SB>Zr<SB>2</SB>(SiO<SB>4</SB>)<SB>y</SB>(PO<SB>4</SB>)<SB>3-y</SB>. General formula (2): Na<SB>x</SB>V<SB>2</SB>(PO<SB>4</SB>)<SB>3</SB>. Here, 1≤y<3 in the general formula (1) and 1≤x≤5 in the general formula (2). <P>COPYRIGHT: (C)2010,JPO&INPIT |
