Abstract Porous carbon nanosheets with open 2D nanostructure have been considered a desirable and high‐efficient energy‐storage material. Herein, N, S, P co‐doped interconnected porous (CPCNs) high defect density ultrathin are prepared by using cork‐shaped soybean aerogel as source. A reasonable design of the preparation technology controls formation distinctive ordered structure intermediates during synthetic process. The as‐prepared CPCN material is made thickness 4.9 nm maximum N‐dopant content 5.83 at. % specific surface area 3586 m 2 g −1 . Due to synergistic effects features, electrode for supercapacitors has capacitance 427 F long cycling stability 97.42 after 10 000 cycles. For lithium‐ion batteries, also exhibits an excellent capacity 1220 mAh at 100 mA rate capability stability. Moreover, scenario through enhance electrochemical performance nano‐inorganic proves scalability in application products.
