PROBLEM TO BE SOLVED: To provide: a negative electrode for an air battery, which is high in capacity and superior in charge and discharge cycle characteristics; and a solid electrolyte air battery using such a negative electrode.SOLUTION: A negative electrode for an air battery comprises an active material layer including: an active material including a first metal element and capable of occluding and releasing oxygen; and a compound 5 including a second metal element and chemically more stable than the active material. A solid electrolyte air battery comprises: a negative electrode 2 composed of the negative electrode for an air battery; a positive electrode 1; and a solid electrolyte 3 between the positive electrode 1 and the negative electrode 2. In the solid electrolyte air battery arranged in this way, the grain growth and sintering of its active material are suppressed even at a high operation temperature and therefore, a high capacity and superior charge and discharge cycle characteristics are achieved. |
