▎ 摘　　要

NOVELTY - Highly reversible secondary zinc-air battery, zinc negative electrode, oxygen positive electrode and electrolyte comprises sulfoxide-based solvent, so that positive electrode reaction is highly reversible in formation and decomposition of zinc oxide during battery operation. USE - Highly reversible secondary zinc-air battery, zinc negative electrode, oxygen positive electrode and electrolyte. ADVANTAGE - The highly reversible secondary zinc-air battery, zinc negative electrode, oxygen positive electrode and electrolyte has high reversibility, high chemical/electrochemical stability, increases shelf life and cycle life, does not need special gas filter film, and is stable to water and carbon dioxide. DESCRIPTION OF DRAWING(S) - The drawing shows schematic diagram of highly reversible secondary zinc-air battery, zinc negative electrode, oxygen positive electrode and electrolyte.
