[en] Highlights: • 3DOM-TiNb₂O₇ hierarchical nanostructure has been successfully prepared. • Our results demonstrate that 3DOM-TiNb₂O₇ anode exhibits good high-rate performances and long cycle life due to the unique pseudocapacitive effects. • Pseudocapacitive contribution of 3DOM-TiNb₂O₇ anode in the total current response was first quantitative calculated. Titanium niobium oxide (TiNb₂O₇) has been regarded as a promising anode material for high-rate lithium ion batteries (LIBs) due to its potential to operate at high rates with improved safety and high theoretical capacity of 387 mA h g⁻¹. Herein, three-dimensionally ordered macroporous (3DOM) TiNb₂O₇ composed of interconnected single-crystalline nanoparticles was prepared using polystyrene (PS) colloidal crystals as a hard template. The final product yields a homogeneous, continuous, and effective honeycomb-like construction. This architecture provides facile Li⁺ insertion/extraction and fast electron transfer pathway, enabling high-performance lithium ion pseudocapacitive behavior, leading to good electrochemical performance. As a result, the 3DOM-TiNb₂O₇ shows a remarkable rate capability (120 mA h g⁻¹ at 50 C) and durable long-term cyclability (82% capacity retention over 1000 cycles at 10 C). The work presented herein holds great promise for future design of material structure, and demonstrates the great potential of TiNb₂O₇ as a practical high-rate anode material for LIBs.
