Recent Progress in Advanced Conjugated Coordination Polymers for Rechargeable Batteries

Abstract Metal‐organic frameworks (MOFs) have been extensively studied and applied as promising active materials in the field of energy storage and conversion. Recently, conductive π‐d conjugated coordination polymers (CCPs) have garnered significant attention due to their high conductivity, high porosity, tunable components, and adjustable pore sizes. These CCPs typically consist of transition metal ions and organic ligands, forming an in‐plane π‐d conjugated system. In this review, a concise summary of the design principles are provided, synthesis methods, and reaction mechanisms of CCPs as electrodes for energy storage systems, including metal‐ion batteries and supercapacitors. In addition, several novel energy storage applications are highlighted, such as metal‐air batteries and photo‐enhanced batteries. Finally, the challenges that need to be addressed is discussed urgently and offer perspectives on the further application of CCPs in more advanced energy storage and conversion systems.
