Nitrogen doped carbon is a burgeoning anode candidate for potassium-ion battery (PIBs) owing to its outstanding attributes. It is imperative to grasp further insight into specific effects of different nitrogen dopants in carbon anode toward advanced K-ion storage. However, the prevailing fabrication method is plagued by the fact that considerable variations in the total N-doping concentration occur in the course of regulating the type of nitrogen dopants, incapable of distinguishing the certain roles of them under similar conditions. Herein, throughout the precise preparation of high edge-N doped carbon (HENC) and high graphitic-N doped carbon (HGNC) harnessing basically identical N-doping levels (5.78 at.% for HENC; 5.07 at.% for HGNC) via chemical vapor deposition route, the effects of edge-N and graphitic-N in the carbon anode on K-ion storage are revisited, offering guidance into the design of low-cost and high-performance PIB systems.
