The present invention belongs to electrochemical technical field, specifically a high specific energy charging full-solid lithium air battery. The battery structure is: firstly an air diffusion layer, then an air electrode, composed of a meso-porous carbon/manganese oxide composite material, an oxygen-reduction catalyst and a macromolecule lithium electrolyte, next a multilayer aqueous vapour cover, not only serving as a electrolyte layer of the battery, but also blocking water an oxidation entering of the air, finally a metal lithium. The whole battery is sealed in the multiplayer metal/plastic, a portable sealing is on the top of the air diffusion layer which is opened when the battery is used, closed when the battery is not used. The invention adopts lithium air battery made by the meso-porous carbon / manganese oxide composite material and the room temperature ionic liquid electrolyte, the capacity achieves 800mAh/g, cycling more than 50 times. In the lithium air battery, the metal lithium has effective protection, making the Li/O2 reaction only in the electrochemical reaction, the lithium air battery not only has battery electrochemical capability, but also has excellent safety ability.
