Herein, a novel strategy involving the manipulation of sulfur and nitrogen is devised to enhance the reaction dynamics and pseudocapacitance characteristics of carbon nanosheets (S&N‐CNS), leading to a superior carbonaceous anode for both potassium (K) and sodium (Na) ion storage. Thus, the well‐designed S&N‐CNS could demonstrate elevated electrochemical performance, including a high specific capacity of 433.9/523.7 mAh/g at 0.1/0.2 A g−1 and a stable cycling life over 2000/3000 cycles at 5.0 A g−1 for K+/Na+ storage, respectively. The promoted performance is benefited by the increased charge transfer capacity, active/defect sites, and ion transport dynamics, as confirmed by various electrochemical measurements and theoretical simulation results. Furthermore, the underlying application is conducted by assembling a potassium ion hybrid capacitor with S&N‐CNSs and an activated carbon (AC) electrode, which could contribute a high energy density of 124.0 Wh kg−1 at a power density of 165.3 W kg−1 and super cycling life over 4000 cycles. This research contributes to advancing the exploration of carbon anodes and fostering the development of alkali metal ion batteries. 10.1002/sus2.70021 http://creativecommons.org/licenses/by/4.0/ |
