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.

新型锌离子电容器的碳基材料
锌离子电容器（ZIC）作为一种新型的具有广阔发展前景的电化学储能（EES）器件，因其融合了高能锌离子电池和大功率超级电容器的优势而倍受人们的关注，因此备受关注。对低成本，长期耐用性和高安全性的需求。尽管如此，对ZIC的调查仍处于起步阶段，许多问题需要解决。尤其是，碳基电极有限的离子吸附能力所带来的挑战严重限制了ZIC的能量密度。因此，决定如何设计一种具有高能量密度的新型碳材料而又不影响其固有功率和长期耐用性已成为一个关键问题。这篇综述系统地总结了准备工作的研究进展，近年来，ZIC中使用的各种碳基材料的形貌，组成和电化学性能都集中在电荷存储机理上。还介绍了在ZIC中应用碳基材料的当前挑战和未来机遇。这篇综述将帮助研究人员进一步了解ZIC，并开发新的EES系统，以满足快速扩展电动汽车和智能电子设备的需求。
