“…[1][2][3] And with the continuous expansion of the electric vehicle market, people have increased the demand for environmentally friendly, renewable resources with the high power density and high energy density. [4,5] Therefore, to solve this problem, it is necessary to study sustainable energy production and storage technology.Among various energy storage devices, supercapacitors, as a very ideal energy storage device have a higher power density than batteries, [6] a higher energy density than traditional capacitors, [7] fast charging speed, [8] and excellent cycle performance, [9] have been studied. Among them, electrode materials play a vital role in the capacitance performance of supercapacitors.…”
