Influence of CO2 on the stability of discharge performance for Li–air batteries with a hybrid electrolyte based on graphene nanosheets

Abstract

The long-term discharge performance of graphene nanosheets for Li–air batteries with hybrid electrolytes shows different behaviour depending on the surface state of graphene. The functional groups on graphene play a more important role than the defect sites for the formation of Li₂CO₃ and electrochemical performance in Li–air batteries with hybrid electrolytes.
