Development of Anode(Zinc Electrode) Materials for Alkaline Zinc Air Battery

Alkaline zinc air battery has the advantages of high specific density,flat discharge voltage,non- toxic,relatively inexpensive and abundant.As the anode materials of alkaline zinc air battery,zinc electrode influences the electro-performance(output power,cycling life,depth of discharge)and store performance of battery.The zinc electrode also has problems as dendrite,shape change,self-corrosion and passivation.The recent research on zinc elec- trode is reviewed and summarized in this paper,including the development in zinc electrode physics performance,elec- trode additive and electrolytic additive,and so on.Moreover,the methods of solving all these problems are introduced and analyzed.
