METAL-AIR BUTTON CELLS AND THE PRODUCTION THEREOF

A method of producing a metal-air button cell including a housing, an air cathode, a metal-based anode and a separator arranged in the housing, the method including printing the air cathode in the form of a planar layer onto a planar substrate by a screen printing process, wherein a paste including a solvent and/or suspending agent, particles made of an electro-catalytically active material, and binder particles made of a hydrophobic plastic material is used for printing, and inserting the laminar composite structure obtained during printing and which includes the planar substrate and the air cathode applied thereto into the housing and combined with the metal-based anode, wherein the planar substrate, onto which the air cathode is printed, is the separator.
