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.
