Lithium‐ion capacitors (LICs) composed of a battery‐type electrode and a capacitor‐type electrode are highly competitive candidates for next‐generation electrochemical energy storage devices, simultaneously achieving high energy and power densities. However, the present LICs are still hindered by the imbalance of electrode kinetics and capacity of anode and cathode. Recently, two‐dimensional (2D) materials with unique structure and appealing properties have received extensive attentions for applications in LICs, with remarkable improvements from charge storage capacity to reaction kinetics. Herein, we review the recent advances in the applications of 2D materials for high‐energy and high‐power LICs. The key advantages and important roles of 2D materials are emphasized for the construction of LICs, including electrochemical active materials, ultrathin conductive and flexible supports for hybridization with other active materials, and 2D functional building blocks for assembling macroscopic hierarchical 3D frameworks. Finally, the challenges and prospects associated with the applications of 2D materials for high‐performance LICs are discussed.

二维材料在高能大功率锂离子电容器中的最新进展和挑战

由电池型电极和电容器型电极组成的锂离子电容器（LIC）是下一代电化学储能设备的极具竞争力的候选产品，同时可实现高能量和功率密度。然而，目前的LIC仍然受到电极动力学和阳极和阴极容量不平衡的阻碍。近年来，具有独特结构和吸引力的二维（2D）材料在LICs中的应用受到了广泛关注，从电荷存储容量到反应动力学的显着改进。本文中，我们回顾了2D材料在高能和大功率LICs中的最新应用进展。二维材料的关键优势和重要作用在LIC的构造中得到了强调，包括电化学活性材料，用于与其他活性材料杂交的超薄导电性和柔性支撑物，以及用于组装宏观层次3D框架的2D功能构造块。最后，讨论了将2D材料应用于高性能LIC的挑战和前景。
