Abstract:
1. A lithium ion oxygen battery comprising: a positive electrode containing a lithium source, and an oxygen storage material; wherein the lithium source comprises a lithium compound except for a combined metal oxide of lithium and another metal; a negative electrode made of a material capable of occluding or releasing lithium ions; and an electrolyte layer sandwiched between the positive electrode and the negative electrode and capable of conducting the lithium ions, wherein the positive electrode, the negative electrode, and the electrolyte layer are housed in a hermetic case, the oxygen storage material occludes oxygen generated from the lithium compound when charging, adsorbs the oxygen on a surface thereof when charging, releases the occluded oxygen when discharging, and desorbs the adsorbed oxygen when discharging, the oxygen storage material is any one of a combined metal oxide expressed by YMnO wherein in a state of being fully charged, the electrochemically active components of the positive electrode consist of the oxygen storage material and oxygen ions absorbed or bonded to the surface of the oxygen storage material.
