PURPOSE:To obtain a lithium-oxide battery which has no deteriorations of a negative electrode and has an improved liquid-leakage resistant performance by preparing the negative electrode from Li, preparing a positive electrode from active carbon supporting an oxygen supplying body, and sealing a battery case. CONSTITUTION:Oxygen gas is supplied into an active carbon powder so as to make oxygen to be absorbed by the active carbon powder. In another case, the active carbon powder is made to support an oxygen supplier, a perfluoro compound in which oxygen is dissolved. After thus treated active carbon powder is molded into a positive electrode 10, the electrode 10, a negative electrode 11 made of lithium metal, and a separator 12 impregnated with electrolyte is installed into a battery case 13. Following that, the case 13 is sealed by use of a negative sealing plate 14 and a gasket 15, without providing any air hole. By the means mentioned above, a lithium-oxygen battery which has a small deterioration, an excellent lequid-leakage resistance and a high output can be obtained. |
