Organic materials‐based cathode for zinc ion battery

The quest for advanced energy storage devices with cheaper, safer, more resource-abundant has triggered intense research into zinc ion batteries (ZIBs). Among them, organic materials as cathode ZIBs have attracted great interest due to their flexible structure designability, high theoretical capacity, environmental friendliness, and sustainability. Although numerous electrode been studied different redox mechanisms proposed in the past decade, electrochemical performance still needs further improvement, require exploration. This paper provides a systematical overview of three types (bipolar-type conductive polymer, n-type conjugated carbonyl compounds, p-type material) on distinct characteristics. We then focus discussing design strategies improve performance. Furthermore, challenges future directions are discussed provide foundation developing organic-based ZIBs.
