Supercapacitors are essential for electrochemical energy storage because of their high-power density, good cycle stability, fast charging and discharging rates, and low maintenance cost. Macrocycles, including cucurbiturils, calixarene, and cyclodextrins, are cage-like organic compounds (with a nanocavity that contains O and N heteroatoms) with unique potential in supercapacitors. Here, we review the applications of macrocycles in supercapacitor systems, and we illustrate the merits of organic macrocycles in electrodes and electrolytes for improving the electrochemical double-layer capacitors and pseudocapacitance via supramolecular strategies. Then, the observed relationships between electrochemical performance and macrocyclic structures are introduced. This comprehensive review describes recent progress on macrocycle-block supercapacitors for researchers.
超级电容器因其高功率密度、良好的循环稳定性、快速的充放电速率和低维护成本，对于电化学能量存储至关重要。大环化合物，包括葫芦脲、杯芳烃和环糊精，是笼状有机化合物（具有包含O和N杂原子的纳米腔），在超级电容器中具有独特的潜力。在此，我们综述了大环化合物在超级电容器系统中的应用，并阐述了有机大环化合物在电极和电解质中通过超分子策略改善电化学双层电容器和赝电容的优点。然后，介绍了观察到的电化学性能与大环结构之间的关系。这篇全面的综述为研究人员描述了大环-块体超级电容器的最新进展。
