Abstract

This article focuses on the development and evaluation of nitrogen/boron co-doped carbon nanosheets (NB-CNs) as anode materials for sodium-ion batteries (SIBs). Using boron-doped MIL-68 as a carbon precursor and dicyandiamide as a nitrogen source and template, the study achieved uniform N and B doping with abundant N–B bonds, creating a two-dimensional porous structure that enhances sodium ion adsorption and transport kinetics. The NB-CNs demonstrated a high reversible capacity of 307.1 mA h g⁻¹ at 0.1 A g⁻¹ and maintained 157 mA h g⁻¹ after 8000 cycles at 4 A g⁻¹, outperforming comparable materials. Additionally, a full cell assembled with NB-CNs as the anode and Na₃V₂(PO₄)₃/C as the cathode showed promising cycling stability and energy density, indicating potential for practical SIB applications.
