摘　　要：Alkaline Al-air batteries(AABs)have attracted considerate attention due to their high theoretical capacity density and energy density with intrinsic safety and low cost.However,severe hydrogen evolution reaction(HER)decreases the discharge performance and increases usage risk,which restricts the development of AABs.In this comprehensive review,a systematic overview of progress in inhibition methods of HER is provided,including anodic alloying,structural treatment,surface modification,additives and non-aqueous electrolytes.Among them,the most efficient method is additives,which was simple and provided the highest inhibition rate.Finally,suggestions and perspectives for future research are offered on improving the commercial application potential of AABs,providing guidance for aqueous metal-air batteries.
