Abstract: With the advantages of high energy density,safe and reliable aqueous electrolyte and low cost,zinc-air batteries show important potential as well as challenge for electrical energy conversion and storage. These batteries used in pure electric vehicles,mobile tools and electricity storage for new energy power generations,have promising market and applications. However,some issues related to electrode structure and electrocatalyst in cathode and zinc dendrite growth in anode restrict its further development and application. This paper analyzes the critical scientific issues in zinc air batteries,especially for the electrocatalyst of air electrode,electrode configuration,dendritic growth in zinc negative electrode,discusses the battery performance in details,and points out the main barriers in developing advanced battery technology. In summary the development of novel electrocatalyst,air electrode,manufacturing technology for long-term cycle life and low cost zinc air batteries are urgent problems to be settled at present.

Key words: zinc air battery, electrocatalyst, air cathode configuration, zinc anode
