Polyvinylpyrrolidone-derived nitrogen-doped carbon-coated MoS

Two-dimensional transition metal dichalcogenides, which display considerable theoretical capacity and large layer spacing, have been regarded as promising candidates as anode materials for sodium-ion batteries (SIBs). However, their low conductivity and large volume change during charge-discharge cycles leads to performance degradation. Herein, polyvinylpyrrolidone (PVP) is used as a soft template to synthesize PVP-derived nitrogen-doped carbon-coated MoS
