: In recent decades, carbon nanomaterials have attracted a lot of attention in the field of energystorage and conversion due to their exceptional mechanical, electrical and chemical properties.Nevertheless, pristine carbon nanomaterials possess inert surface and uncontrollable band gap, greatlyrestricting their application. Doping heteroatoms into carbon skeleton has been verified as a validstrategy to adjust the electronic structure and physicochemical properties of carbon nanomaterials, whichopens a new avenue to improve the electrochemical performance of carbon nanomaterials. Herein, wefirst give a simple description of carbon nanomaterials and the necessity of doping heteroatoms. Then wediscuss and analyze the doping types and doping methods of heteroatoms-doped carbon nanomaterials.Afterwards, the specific electrochemical applications of heteroatoms-doped carbon nanomaterials aresystematically introduced from the perspective of fuel cells, lithium-ion batteries, lithium-sulfur batteriesand supercapacitor. Eventually, the possible challenges in the near future for the synthesis ofheteroatoms-doped carbon nanomaterials and their related electrochemical application in the field ofenergy storage and conversion are summarized.
