Summary: The development of emerging Na-Se batteries is hindered by technical bottlenecks such as polyselenide shuttling and material volume variation. In this study, a nanorod-like trimodal hierarchical porous carbon (THPC) host is fabricated for advanced Na-Se batteries. The THPC possesses a trimodal nanopore structure and functions as a good accommodator of Se molecules, a reservoir of polyselenide intermediates, a buffer for volume expansion, and a promoter for electron/ion transfer.

Summary: Due to its abundant precursors, simple preparation, and environmental friendliness, nitrogen-doped carbon is regarded as a promising anode material for potassium-ion batteries (PIBs). In this study, nitrogen-doped carbon material (NC-2) was synthesized using exfoliated g-C3N4 as a precursor, combined with sucrose, and subjected to hydrothermal and high-temperature pyrolysis. NC-2 exhibited a high nitrogen content, porous layered structure, and large interlayer spacing. As the anode for PIBs, NC-2 demonstrated a high reversible capacity of 261.07 mAh g-1 at 0.1 A g-1 and an impressive rate performance of 153.36 mAh g-1 at 2 A g-1. The excellent performance of NC-2 can be attributed to its porous layered structure, enlarged interlayer spacing promoting ion diffusion, and the presence of abundant active sites due to nitrogen doping. These results indicate the great potential of NC-2 as a PIBs anode material.
