Supercapacitors (SCs), also known as ultracapacitors, should be one of the most promising contenders for meeting the needs of human viable growth owing to their advantages: for example, excellent capacitance and rate efficiency, extended durability, and cheap materials price. Supercapacitor research on electrode materials is significant because it plays a vital part in the performance of SCs. Polyaniline (PANI) is an exceptional candidate for energy-storage applications owing to its tunable structure, multiple oxidation/reduction reactions, cheap price, environmental stability, and ease of handling. With their exceptional morphology, suitable functional linkers, metal sites, and high specific surface area, metal-organic frameworks (MOFs) are outstanding materials for electrodes fabrication in electrochemical energy storage systems. The combination of PANI and MOF (PANI/MOF composites) as electrode materials demonstrates additional benefits, which are worthy of exploration. The positive impacts of the two various electrode materials can improve the resultant electrochemical performances. Recently, these kinds of conducting polymers with MOFs composites are predicted to become the next-generation electrode materials for the development of efficient and well-organized SCs. The recent achievements in the use of PANI/MOFs-based electrode materials for supercapacitor applications are critically reviewed in this paper. Furthermore, we discuss the existing issues with PANI/MOF composites and their analogues in the field of supercapacitor electrodes in addition to potential future improvements.
超级电容器（SCs），也被称为超级电容器，由于其优点，应该是满足人类可持续发展需求最有前途的竞争者之一：例如，出色的电容和倍率效率、延长的耐久性以及低廉的材料价格。对超级电容器电极材料的研究具有重要意义，因为它在超级电容器的性能中起着至关重要的作用。聚苯胺（PANI）因其可调节的结构、多种氧化/还原反应、低廉的价格、环境稳定性和易于处理，是储能应用的理想候选材料。金属有机框架（MOFs）具有特殊的形态、合适的功能连接体、金属位点和高比表面积，是电化学储能系统中用于制造电极的杰出材料。聚苯胺和金属有机框架（PANI/MOF复合材料）作为电极材料的组合展现出额外的优势，值得探索。这两种不同电极材料的积极影响可以提高最终的电化学性能。最近，这类导电聚合物与金属有机框架的复合材料预计将成为开发高效且有序的超级电容器的下一代电极材料。本文对基于聚苯胺/金属有机框架的电极材料在超级电容器应用中的最新成果进行了批判性综述。此外，除了潜在的未来改进之外，我们还讨论了聚苯胺/金属有机框架复合材料及其类似物在超级电容器电极领域存在的问题。
