This study synthesized a hard carbon anode material (HC-N1300) with hierarchical micro/mesoporous structure through biomass-derived nitrogen doping, aiming to explore its application in sodium-ion batteries (SIB). Structural characterization reveals that HC-N1300 possesses well-developed micro/mesop...
