Constructing N, B co-doped carbon nanosheets with pyridine N-B sites for boosting sodium-ion storage.

Carbonaceous materials have demonstrated extensive potential as anodes for sodium ion batteries (SIBs). Nevertheless, large-scale commercial use is severely hampered by the slow reaction kinetics and rapid capacity fading. Heteroatom doping can create abundant active sites to improve the ion adsorption properties of carbon materials.
