The effect of plasma parameters on the surface treatment of air cathode for zinc-air battery — •He Li, Christian Schulze, Sadegh Askari, and Jan Benedikt — Institute of Experimental and Applied Physics, Kiel University, Germany

Plasma technology is of vital importance in the research field of nanomaterials which offers a green and efficient process for functionalization and treatment of surfaces. Most of the previous researches focus on the process parameters, but the relationship between plasma properties, such as ion energy or fluxes of reactive species, and materials properties is still unclear. In this work, a new reactor was assembled which is combining ICP plasma with CCP bias to control the plasma density and ion energy separately during the treatment, and transition metal oxides were used as the substrate to compare the electrochemical performance before and after plasma treatment. The plasma parameters during treatment were measured by the energy-resolved ion mass spectrometry which were analyzed with the corresponding catalytic performances to optimize the treatment process and fundamentally understand the reaction processes and mechanisms between plasma and material surfaces, thus providing a theoretical basis for the future application in the material researches.
