Zinc‐ion capacitors (ZICs), as a new type of electrochemical energy storage (EES) device with great development prospects, have garnered considerable attention because they integrate the advantages of high‐energy zinc‐ion batteries and high‐power supercapacitors to meet people's demand for low‐cost, long‐term durability and high safety. Nevertheless, the investigation of ZICs remains in its infancy, and many problems need to be resolved. In particular, the challenge caused by the finite ion adsorption capacity of carbon‐based electrodes gravely limits the energy density of ZICs. Consequently, determining how to design a new type of carbon material with a high energy density without affecting its inherent power and long‐term durability has become a key issue. This Review systematically summarizes the research progress in the preparation, morphology, composition, and electrochemical properties of various carbon‐based materials used in ZICs in recent years, focusing on the charge‐storage mechanism. Current challenges and future opportunities in the application of carbon‐based materials in ZICs are also presented. This Review will help researchers understand ZICs further and develop new EES systems to satisfy the needs of quickly expansion electric automobiles and intelligent electronic device.
