“…The pursuit of high-performance energy storage devices has become increasingly imperative in the face of escalating energy demands and imperative to transition toward sustainable energy sources. − Supercapacitors, − as one kind of important source of energy storage devices and power outputs, have attracted much attention because of their high pulse power density, long cycle life, fast charging–discharging rate, and simple principle. In the past several decades, a huge number of studies − have been carried out to develop novel supercapacitor electrode materials with high specific capacitance as well as excellent cycling stability.…”
