摘要:

石墨烯独特的二维空间结构使其具有优异的导电性能、力学性能以及超大的比表面积,被认为是颇具潜力的新型储能材料,是目前储能研究的热点之一。 但是石墨烯易团聚、表面光滑且呈惰性而不利于与其它材料的复合,导致其应用受到限制。 石墨烯掺氮可改变其电子结构,增加表面的活性位,从而提高其应用于储能器件时的电化学性能。 本文综述了近几年氮掺杂石墨烯的制备方法以及其在超级电容器、锂离子电池、锂空电池以及锂硫电池等化学储能领域中的应用,指出了目前氮掺杂石墨烯在制备和储能应用中关注的核心问题,并对氮掺杂石墨烯的发展前景进行了展望。

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.
