Abstract

Abstract: The hexagonal layered nickel thiophosphate (NiPS3 ) has a great application potential in the field of rechargeable batteries due to the high theoretical specific capacity. In this paper, we described a graphene-like carbon nanosheets (GCSs) substrate with nitrogen-doped by biomass carbonization from Typha angustifolia L. The small sized, layered and good electronic conductive NiPS3 was grown on the GCSs under the 'induction effect' of the uniformly distributed nitrogen atoms. The obtained NiPS3 @GCSs composite was used for anode of sodium-ion batteries (SIBs) and exhibited an excellent rate performance under high current density. The high capacity reached 765 mA h g −1 at the current density of 10 A g −1, and still maintained the capacity of 522 mA h g −1 after 100 cycles, which indicates that the NiPS3 @GCSs composite can be used as high-performance anode materials of SIBs for ultra-fast charge/discharge. Graphical abstract: The NiPS3 was anchored on the nitrogen-doped graphene-like carbon nanosheets (GCSs), which were obtained by biomass carbonization from Typha angustifolia L. The well-designed NiPS3 @GCSs can be used for sodium-ion batteries and exhibited an excellent rate performance. Image 1 Highlights: The nitrogen-doped graphene-like carbon nanosheets (GCSs) were obtained by low-cost biomass carbonization. The NiPS3 was grown on the GCSs under the 'induction effect' of the uniformly distributed nitrogen atoms. The NiPS3 @GCSs exhibited an excellent rate performance for ultra-fast charge/discharge of sodium-ion batteries.
