Abstract:

Aqueous zinc ion battery is a novel battery system with the characters of low price,safety,environmental friendly,as well as high power density,which has good application value and development prospect in many fields such as energy stor-age.The progress of the basic research and industrialization of aqueous zinc ion battery was summarized from the aspects of cathodes,zinc anode,and electrolyte,and the industrial development of manganese dioxide cathode materials,battery assem-bly and application technologies were introduced.The feasibility and difficulties for future research and industrial development were highlighted.Three main issues that needed to be urgently solved were proposed.Firstly,the energy storage mechanism of aqueous zinc ion battery system was still needed in-depth study,which was important to guide the design of high performance cathode and anode materials.Secondly,the lack of key links in the industrial chain such as high-purity manganese dioxide cathode material,corrosion-resistant collector and puncture resistant diaphragm restricted the development of commercial batteries.Finally,from laboratory to pilot test and large-scale amplification,the battery performance was significantly reduced, and the systematic electrode preparation and battery assembly process was still needed systematic research.

Key words: aqueous zinc ion battery, cathode material, Zn anode, industrialization
