<P>PROBLEM TO BE SOLVED: To provide a solid electrolyte, and a battery adopting this. <P>SOLUTION: This is the solid electrolyte expressed by the following chemical formula 1: Li<SB>x</SB>Si<SB>y</SB>M<SB>z</SB>O<SB>v</SB>N<SB>w</SB>(chemical formula 1). In the formula, 0.3≤x≤0.46, 0.05≤y≤0.15, 0.0016≤z≤0.05, 0.42≤v≤0.5, and 0≤w≤0.029, and M shows one or more selected from a group composed of Nb, Ta, P and W. This lithium battery or thin film battery is the solid electrolyte in which ion conduction property and electrochemical stability are improved, and the lithium battery adopting this. <P>COPYRIGHT: (C)2004,JPO |
