Air battery and method for producing air electrode for air battery

摘要

An air battery that is excellent in heavy-load discharge characteristics and storage characteristics is provided by ensuring the stability of the three-phase interface of a catalyst layer of an air electrode. The air battery has an air electrode including a catalyst layer that is bonded under pressure to a current collector and a water-repellent film. The catalyst layer includes a catalyst for reducing oxygen, a promoter for decomposing a product of the oxygen reduction, conductive carbon, and a binder. A non-polymeric fluorine compound is added to the catalyst layer in order to enhance the water repellency of the catalyst layer.
