Research progress on the cathode and anode of aqueous zinc ion battry

Abstract

Electrochemical energy storage problems become a worldwide research direction. Now Lithium-ion batteries (LIBs) are the most common battery product. However, LIBs still has many shortcomings such as, safety problems, a scarcity of lithium, and high price. Rechargeable aqueous-based zinc ion batteries (AZIBs) with lower costs, fewer safety risks as well as abundant zinc reserves have attracted extensive research interest. For the current electrode materials of AZIBs, for example, Mn-based materials, V-based materials and metallic zinc, scientists have done in-depth research to develop the performance of the materials, but complex processes are still inevitable. As a result, sustainable and scalable manufacturing technology and electrode materials with high capacity and the longer service life is the research direction.
