摘　　要：Electrochemical energy storage(EES)is a key technology in global research that focuses on the efficient storage and utilization of electrical energy generated from intermittent sources.The development of EES systems with high energy and power densities is essential for meeting the future energy demands of electrochemical capacitors,such as capacitors,which can store electrical energy obtained from intermittent sources and enable rapid energy transfer and transformation.Electrical double-layer capacitors(EDLCs)within porous carbon materials(Fig.1(a))are commercially popular because of their excellent conductivity and relatively low cost.Despite their advantages,the complex structure of nanoporous carbon materials hinders the optimization of supercapacitor performance.Although previous research has suggested that adjusting the pore size of nanoporous carbon materials can enhance their capacitive performance,conflicting reports and the lack of a definitive correlation between capacitance and pore size remain issues[1].Understanding the relationship between the structure of carbon materials and their capacitance is crucial for designing devices with high energy densities.
