This work provides a constructive avenue for designing high-performance ZIHCs electrode materials. The assembled ZIHCs exhibit excellent rate performance (140 mA h g-1 at 0.2 A g-1 and 86.2 mA h g-1 at 6.4 A g-1), high energy density and power density (111.1 W h kg-.2 W kg-1, respectively). Based on a clear understanding of the carbonization mechanism, assisted by DFT theoretical simulations, we find the optimal carbonization temperature of the DCP-derived porous carbon for ZIHCs. More importantly, the morphology evolution, heteroatom doping, and defect generation of the DCP during carbonization are clarified. In this study, we developed a simple self-template method for preparing N-doped porous carbon from D-calcium pantothenate (DCP). Cholecalciferol (vitamin D 3) is also used along with calcium to prevent and treat bone diseases such as rickets (softening and weakening of bones in children caused by lack of vitamin D), osteomalacia (softening and weakening of bones in adults caused by lack of vitamin D), and osteoporosis (a condition in which the bones become thin and weak a. However, most of the reports focus on the preparation method and modification of porous carbon, and rarely explore the mechanisms of material synthesis/fabrication in the carbonization process. Due to the environmental friendliness and high safety of aqueous Zn-ion hybrid capacitors (ZIHCs), the exploration of high-performance porous carbon electrodes for ZIHCs has recently attracted significant attention.
