摘　　要：锂离子电容器的正、负极材料能量存储机制不同,导致容量和动力学差距较大。对正负极进行容量和动力学的匹配,实现比能量和比功率的平衡,是锂离子电容器研究的关键。从材料体系、工艺设计和电极结构等3方面详细综述近年来锂离子电容器在正负极匹配方面的进展,包括碳基正极材料比能量的提升策略、工艺设计对负极性能的影响以及电极结构设计对锂离子电容器电化学性能的影响。对锂离子电容器在正负极匹配方向的发展进行展望。The cathode and anode materials of Li-ion capacitor have different energy storage mechanisms,resulting in a large gap between the capacity and kinetics.Matching the capacity and dynamics of the cathode and anode to achieve the balance of specific energy and specific power is the key to the research of Li-ion capacitors.The progress in recent years in the matching of anode and cathode of Li-ion capacitor is summarized from the aspects of material system,process design and electrode structure,including the improvement strategy of specific energy of carbon-based cathode materials,the influence of process design on the performance of anode as well as the influence of electrode structure design on the electrochemical performance of Li-ion capacitor.The development of Li-ion capacitor in the direction of matching of the cathode and anode is prospected.
