An irreversible capacity is further reduced in a non-aqueous air battery. A non-aqueous air battery includes a positive electrode having an oxygen redox catalyst, a negative electrode having a negative electrode active material, an electrolyte interposed between the positive electrode and the negative electrode, and conducting Li ions. It has. Here, the negative electrode active material is a lithium-based material on which a film containing any one or more of Na, K, Rb, Cs, and Fr is formed. The lithium-based material is obtained by bringing a treatment liquid containing a non-aqueous solvent having a sulfoxide group and any one or more of Na, K, Rb, Cs, and Fr dissolved in the solvent into contact with the lithium-based material. It is preferable that a film containing any one or more of Na, K, Rb, Cs, and Fr is formed in advance on the system material. [Selection] Figure 1 |
