PROBLEM TO BE SOLVED: To provide a lithium-air electrochemical cell.SOLUTION: The battery comprises: an anode compartment; a cathode compartment; and a lithium ion conductive film separating the anode compartment from the cathode compartment. The anode compartment includes an anode. The anode has lithium, a lithium alloy, or a porous material allowed to adsorb or release lithium and a lithium ion electrolyte. The cathode compartment includes: an air electrode; an ionic liquid capable of supporting the reduction of oxygen; and a potassium superoxide of a dissolution concentration. In the cathode compartment, a lithium ion concentration is lower than a potassium ion concentration.SELECTED DRAWING: Figure 1 【課題】リチウム空気電気化学セルが提供される。【解決手段】電池は、アノード区画と、カソード区画と、カソード区画からアノード区画を分離するリチウムイオン導電膜とを含む。アノード区画はアノードを含む。アノードは、リチウム、リチウム合金、または、リチウムおよびリチウムイオン電解質の吸着および放出を可能にする多孔質材料を有する。カソード区画は、空気電極、酸素の還元をサポートすることができるイオン液体、および溶解濃度の超酸化カリウムを含む。カソード区画内のリチウムイオン濃度はカリウムイオンの濃度と比べて低い。【選択図】図１
