Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a metal-air battery and a discharge test system. Background technique [0002] A metal-air battery is a battery system composed of a fuel such as an active metal as the negative electrode, an aqueous phase or an organic phase such as an alkaline or neutral salt as the electrolyte, and an air diffusion electrode as the positive electrode. At present, metals commonly used as metal-air anode materials include aluminum, magnesium, zinc, iron, and sodium. The positive pole is an air diffusion electrode, which is composed of a catalyst layer, a diffusion layer, and a current collecting net. In the metal-air battery system, the metal negative electrode reacts with the electrolyte to release electrons, and the released electrons flow to the air positive electrode through the external load. After the air electrode receives the electrons, it undergoes a reduction reaction with water, so...
