PROBLEM TO BE SOLVED: To provide a separator including a porous film made of polyolefin or polytetrafluoroethylene and having a nonionic surface active agent applied on the surface so as to improve high output characteristics of an air battery. SOLUTION: The air battery is provided with a battery case formed by using a positive electrode case 1 having an air hole 3 and a negative electrode case 10, a positive electrode catalyst layer 4 positioned inside the positive electrode case 1 of the battery case, a gel negative electrode 9 positioned inside the negative electrode case 10 of the battery case and including zinc and the separator 8 arranged between the positive electrode catalyst layer 4 and the gel negative electrode 9. The separator 8 includes the porous film 8a made of polyolefin or polytetrafluoroethylene and having the nonionic surface active agent applied on the surface. COPYRIGHT: (C)2008,JPO&INPIT |
