Abstract:

The unique two-dimensional spatial structure gives graphene excellent chemical and physical properties and huge specific surface area, which makes graphene a very promising material for energy storage applications and a research hotspot recently. Irreversible agglomeration, smooth surface and inertness result in the dramatic reduction of the available active surface of graphene, which limits its blending with other materials. In recent years, doping graphene with nitrogen reforms its electronic structure and increases surface active sites, promoting its electrochemical performance in the field of energy storage. This paper reviews the current status of nitrogen-doped graphene synthesis and recent progress in the use of nitrogen-doped graphene in chemical energy storage, including supercapacitors, Li-ion batteries, Li-air batteries and Li-S batteries. Finally, key issues related to preparations and applications of nitrogen-doped graphene are briefly discussed as well, and the development prospect of nitrogen-doped graphene is prospected as well.

Key words: nitrogen-doped grapheme, preparation, chemical energy storage, supercapacitor, lithium ion batteries
