Long-life zinc electrodes achieved by oxygen plasma functionalization

Abstract

A facile oxygen plasma treatment strategy is proposed to promote zinc dendrite inhibition by modifying the surface oxygen functional groups. The plasma-treated zinc electrodes achieved an extended working lifespan of 3800 h with an average Coulombic efficiency of over 99% for 1000 cycles when applied in full batteries. This work provides great prospects for the fabrication of long-life zinc batteries for grid systems.
