Energy storage devices are recognized as environmentally friendly technologies. Supercapacitors, known for their high cycle stability, have been proposed as potential alternatives to fossil fuels. Recent studies have focused on selecting suitable electrode materials to achieve energy storage systems with high stability, high specific capacity, and biocompatibility. In particular, carbon-based electrode materials, such as graphene oxide, activated carbon, carbon nanotubes, and carbon-based quantum dots, have attracted considerable attention due to their intrinsic properties, such as high conductivity and stability. However, carbon materials alone exhibit limitations, such as low energy density and low specific capacitance. To address this limitation, the synergistic effect of carbon materials has been combined with other electroactive materials to develop electrode materials with enhanced supercapacitor properties. The present study also investigates the supercapacitor performance of carbon-based nanocomposites. It examines the effect of each carbon material (AC, CNT, GO, rGO) on improving the performance of other electroactive materials, including metal oxides, metal sulfides, MXenes, MOFs, and conductive polymers. This study provides valuable insights for further studies on carbon-based electrode materials for supercapacitor applications.
储能设备被认为是环保技术。超级电容器以其高循环稳定性而闻名，已被提议作为化石燃料的潜在替代品。最近的研究集中在选择合适的电极材料，以实现具有高稳定性、高比容量和生物相容性的储能系统。特别是，基于碳的电极材料，如氧化石墨烯、活性炭、碳纳米管和碳基量子点，因其固有特性，如高导电性和稳定性，而受到了相当大的关注。然而，仅碳材料存在局限性，如能量密度低和比电容低。为了解决这一局限性，碳材料的协同效应已与其他电活性材料相结合，以开发具有增强超级电容器性能的电极材料。本研究还研究了碳基纳米复合材料的超级电容器性能。它考察了每种碳材料（活性炭、碳纳米管、氧化石墨烯、还原氧化石墨烯）对改善其他电活性材料性能的影响，这些电活性材料包括金属氧化物、金属硫化物、MXenes、金属有机框架和导电聚合物。本研究为进一步研究用于超级电容器应用的碳基电极材料提供了有价值的见解。
