Summary Highly graphitic nitrogen‐doped carbon nano‐onions (N‐CNO) have attracted much attention in the field of energy storage device applications. Herein, we have synthesized N‐CNO by a simple flame pyrolysis method for symmetric and asymmetric (ASC) supercapacitor devices. The nitrogen doping is...
