PURPOSE:To provide a layered lithium secondary battery by which the battery service life can be lengthened by preventing adverse influence on a battery raw material or battery reaction caused by oxygen. CONSTITUTION:Current collecting bodies 10 and 12, a positive electrode material 11, a separator 14 or solid electrolyte containing electrode quality and a negative electrode material 13 are respectively formed in a rectangular shape, and these are alternately layered by one or more sets, and a battery element assembly 1 is constituted. The battery element assembly 1 is sealed in an outer case 2, and oxygen absorbent 8 is housed and sealed in the case 2. Oxygen entering the case 2 is absorbed by the oxygen absorbent 8. |
