Carbon@FeSe nanocomposites with homogeneous hollow microspherical and nanotubular structures are prepared using sulfonated polystyrene microspheres and sulfonated poly(divinylbenzene) nanotubes as both the template and carbon source. Benefiting from their hollow core‐shell and hierarchical micro/nanostructures, the carbon@FeSe nanocomposites as the anode material of Li‐ion batteries exhibit high capacities with a steady discharge plateau of 1.5 V (vs. Li/Li + ), stable cycling performance (700 mAh g −1 in the 200th cycle at 800 mA g −1 ), and good rate behavior (620 mAh g −1 at 16 A g −1 ). The steady discharge plateau of carbon@FeSe, together with its high capacity, renders it a promising anode material for Li‐ion batteries.
