2D composites with S doping into N-rich carbon nanosheets are fabricated, whose interlayer distance becomes large enough for Na insertion and diffusion. The large surface area and stable structure also provide more sites for Na adsorption, leading to high Na-storage capacity and excellent rate performance. Moreover, Faradaic reactions between Na and tightly bound S is beneficial for further improvement of Na-storage capacity.
