Zusammenfassung:In the contemporary era of technological advancement, the escalating energy consumption paralleling enhanced living standards necessitates sustainable and eco-friendly energy solutions. Supercapacitors (SCs), lauded for their high capacitance and minimal environmental impact, have emerged as a focal point in this pursuit. Central to SCs’ efficacy are the electrode materials, with nickel-based compounds gaining prominence due to their high theoretical capacitance, affordability, ecological compatibility, ease of synthesis, and chemical stability. Despite these merits, challenges such as inadequate rate capability and cycling property impede their broader applications. This review summarizes the latest advancements in nickel-based composite materials for SC electrodes. It comprehensively discusses their characteristics, fabrication techniques, morphological attributes, and strategies for performance enhancement. The review also analytically explores the diverse electrochemical properties of SCs, offering insights into the underlying causes. Concluding with a discussion on prevailing challenges and potential resolutions, it anticipates future directions in nickel-based supercapacitor electrode material development.
