The present invention provides a new rocking-chair-type battery employing oxygen ions as a charge shuttle that can be used to replace lithium ion batteries. The battery of the present invention is an oxygen shuttle battery comprising two electrodes that are comprised of a compound capable of oxygen intercalation at least in part and an electrolyte permeable to oxygen atoms that is present between the two electrodes. The compound capable of oxygen intercalation is, for example, at least one compound selected from the compound denoted by the general formula AMO z , where A denotes 1 or 2 or more monovalent elements, divalent elements, or trivalent elements, and M denotes 1 or 2 or more monovalent elements, divalent elements, or trivalent elements, with 2.0<Z≦3.0. |
