<P>PROBLEM TO BE SOLVED: To provide a Lithium ion conductor having high ion-conductivity and a whole solid Lithium ion secondary battery having excellent large current-discharge properties. <P>SOLUTION: A Lithium ion conductor comprises a compound oxide with Li, P, O, halogen element X, and element L as constituent elements; and is represented by a composition formula: Li<SB>a</SB>PO<SB>b</SB>X<SB>c</SB>L<SB>d</SB>. The halogen X is at least one member selected from the group consisting of F, Cl, Br, and I, and the element L is at least one member selected from the group consisting of Ti, Zr, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co, Ni, Cu, Ag, and Au. In the composition formula, the references a, b, c, and d represent: 0.05≤a≤6, 0.5≤b≤10, 0.05≤c≤5, 0.0005≤d≤1.5. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
