Mesostructured niobium (Nb)-doped TiO₂-carbon (Nb-TiO₂-C) composites are synthesized by a hydrothermal process for application as anode materials in Li-ion batteries. The composites have a hierarchical porous structure with the Nb-TiO₂ nanoparticles homogenously distributed throughout the porous carbon matrix. The Nb content is controlled (0–10 wt%) to investigate its effect on the physico-chemical properties and electrochemical performance of the composite. While the crystalline/surface structure varied with the addition of Nb (d-spacing of TiO₂: 0.34–0.36 nm), the morphology of the composite remained unaffected. The electrochemical performance (cycle stability and rate capability) of the Nb-TiO₂-C composite anode with 1 wt% Nb doping improved significantly. First, a full cut-off potential (0–2.5 V vs. Li/Li⁺) of Nb-doped composite anode (1 wt%) provides a higher energy utilization than that of the …​
