Nitrogen-doped porous carbon has attracted great attention in lithium ion batteries (LIBs). Herein, new three-dimensional nitrogen-doped porous carbon frameworks (N-PCFs) doped with a nitrogen content up to 19 atom % through sintering nitrogen-doped carbon dots (CDots) at 800 °C have been generated. Beneficial with regard to their large surface area and high nitrogen doping content, the N-PCFs-based LIBs display high change/discharge capacity (1437 mAh g –1 at 0.1 A g –1 ) and considerable rate and cycling performance, manifesting their potential application for Li + storage.
