Most reported carbonaceous anodes of potassium‐ion batteries (PIBs) have limited capacities. One approach to improve the performance of carbon anodes is edge‐nitrogen doping, which effectively enhances the K‐ion adsorption energy. It remains challenging to achieve high edge‐nitrogen doping due to th...
