NON-AQUEOUS ELECTROLYTE CELL |
摘要 |
Provided is a nonaqueous electrolyte battery having a high charge-discharge cycle capability in which the battery capacity is less likely to decrease even after repeated charge and discharge. The nonaqueous electrolyte battery includes a positive-electrode layer 1, a negative-electrode layer 2, a solid electrolyte layer 3 interposed between the positive-electrode layer 1 and the negative-electrode layer 2, and a boundary layer 4 between the negative-electrode layer 2 and the solid electrolyte layer 3, the boundary layer 4 maintaining the bond between the negative-electrode layer 2 and the solid electrolyte layer 3. The negative-electrode layer 2 at least contains Li. The boundary layer 4 at least contains a group 14 element in the periodic table. The boundary layer 4 has a thickness of 50 nm or less. |
