PROBLEM TO BE SOLVED: To solve the problem of a battery including a negative electrode having a capacity of discharging metal ions, a positive electrode which makes a liquid such as water or sea water contribute to battery reaction, and an inorganic solid electrolyte that since the inorganic solid electrolyte is in contact with the positive electrode for a long time, deterioration occurs from the boundary surface of the inorganic solid electrolyte to the positive electrode, thus causing reduction of battery capacity or low output performance.SOLUTION: The battery includes a positive electrode, a negative electrode of metal lithium or a lithium alloy having a capacity of discharging metal ions, and an inorganic solid electrolyte. The positive electrode is configured to hold an active material and a solution also serving as an electrolyte, and has a catalyst material having a capacity of reducing and decomposing oxygen and/or water. Since a porous material is provided between the positive electrode and the inorganic solid electrolyte, the positive electrode and the inorganic solid electrolyte are in non-contact with each other. |
