“…Moreover, all the Ti 4+ and Nb 5+ ions are disordered in octahedral sites sharing corners and edges. Such open Wadsley–Roth shear structure can lead to a large Li‐ion diffusion coefficient, which shows promising applications in energy storage systems . In addition, similar to Nb 2 O 5 ‐based electrodes, TiNb x O 2+2.5 x family have a high operating voltage of ≈1.6–1.7 V (vs Li + /Li), which can match well with the lowest unoccupied molecular orbital (LUMO) of the organic liquid‐carbonate electrolyte.…”

“…Nonetheless, they are limited by their lower theoretical capacity (168 and 175 mA h g −1 for TiO 2 and Li 4 Ti 5 O 12 , respectively). Niobium‐based oxides anodes are rasing more attention with higher theoretical capacity (Nb 2 O 5 ≈200 mA h g −1 and TiNb x O 2+2.5 x compounds ≈388–401 mA h g −1 ) . Niobium‐based oxides are a big family including Nb 2 O 5 , TiNb 2 O 7 , Ti 2 Nb 10 O 29 , TiNb 6 O 17 , TiNb 24 O 62 , and so on.…”

Niobium‐based oxides including Nb2O5, TiNbxO2+2.5x compounds, M–Nb–O (M = Cr, Ga, Fe, Zr, Mg, etc.) family, etc., as the unique structural merit (e.g., quasi‐2D network for Li‐ion incorporation, open and stable Wadsley– Roth shear crystal structure), are of great interest for applications in energy storage systems such as Li/Na‐ion batteries and hybrid supercapacitors. Most of these Nb‐based oxides show high operating voltage (>1.0 V vs Li+/Li) that can suppress the formation of solid electrolyte interface film and lithium dendrites, ensuring the safety of working batteries. Outstanding rate capability is impressive, which can be derived from their fast intercalation pseudocapacitive kinetics. However, the intrinsic poor electrical conductivity hinders their energy storage applications. Various strategies including structure optimization, surface engineering, and carbon modification are effectively used to overcome the issues. This review provides a comprehensive summary on the latest progress of Nb‐based oxides for advanced electrochemical energy storage applications. Major impactful work is outlined, promising research directions, and various performance‐optimizing strategies, as well as the energy storage mechanisms investigated by combining theoretical calculations and various electrochemical characterization techniques. In addition, challenges and perspectives for future research and commercial applications are also presented.

Fast charging of lithium ion batteries is essential for next‐generation energy‐storage systems. However, the poor ionic and electronic transport of anodes with its rather high mass loading limits the practical applications of this technology. Herein, a multiscale design from niobium titanium oxide anode material to electrode structure is proposed for fast charging lithium ion batteries with a practical level of areal capacity (3 mAh cm−2). At the atomic scale, the introduction of oxygen vacancy and surface carbon coating enables niobium titanium oxide (TiNb2O7−x@C) to possess excellent ionic and electronic conductivity. For the microscopic electrode structure, 1D TiNb2O7−x@C fibers are tightly assembled to form a high‐speed transport network of ions and electrons throughout the electrode. As a result, the obtained TiNb2O7−x@C electrode shows excellent rate capability (1.83 mAh cm−2 at 1 C) and cycling stability under an areal capacity of 3 mAh cm−2 (2.35 mAh cm−2 after 100 cycles at 0.5 C) in half‐cells. Significantly, a full‐cell coupled with practical level mass loading of lithium cobalt oxide cathode is demonstrated to deliver 1.55 mAh cm−2 at 3 C for the first time.
