METAL AIR BATTERIES INCLUDING METAL FOAM AND METHOD THEREOF

摘要

PURPOSE: A metal-air battery of high reliability/stability is provided to maintain a pore structure continuously using metal foam as an air anode and have a pore structure of various sizes and distributions and to control a structure of a catalyst layer and a pore structure easily. CONSTITUTION: A metal-air battery comprises a metal cathode, an electrolyte, and an anode. An anode comprises metal foam. The metal foam has an average bubble diameter of 1nm-10mm and a porosity of 10-99%. Metal foam is one or more selected from the element of a I-a group, a II-a group, a III-a group, a VI-a-VIII group, and a I-b-VI-b group. Solid electrolyte is used as an electrolyte. A solid electrolyte is selected from polyethylene oxide, polypropylene oxide, polyacrylonitrile group, LiClO4, LiPF6, LiBF4, LiAsF6, LiLaTiO, and LiLaZrO.
