APPLICATION OF CARBON-BASED MATERIALS IN METAL-AIR BATTERIES: RESEARCH, DEVELOPMENT, COMMERSIALIZATION

Metal-air cells have been developed, comprising a carbon air gasdiffusion electrode providing low polarization and stable long-term operation and metal anode with low self-discharge, operational at high current densities. The mechanism of gas-transport in the hydrophobic gas layer of the air electrode is investigated. Various carbon-based catalysts for the electrochemical oxygen reduction were tested. Methods for diagnostic of the activity and transport properties of the catalysts are proposed. A range of metal air cells developed in this laboratory is presented.
