“…3c). The peaks centered at 530.7 and 532.1 eV are ascribed to the TieO and CeO linkage separately [61]. The little bump around 533.3 eV can be attributed to the TieOH (derived from surface adsorbed water), which is in good agreement with previous work [62,63] and FT-IR spectrum presented in Fig.…”

“…Combining such nanostrucrtured materials with carbon‐based systems is also an attractive strategy to improve the diffusion capability of Li + /e − in TiO 2 . For instance, Jiang et al combined anatase/TiO 2 ‐B with conductive carbon and reduced graphene oxide (rGO), to form a hierarchically porous carbon‐coated mixed‐phase TiO 2 nanosheet/rGO composite (TiO 2 @C/rGO) through a one‐pot solvothermal process . This TiO 2 @C/rGO form different hierarchy levels in a 3D, porous and conducting structure that exhibited an excellent capacity of 158.6 mAh g −1 after 500 cycles at 800 mA g −1 in a voltage window of 0.01–3.0 V. The interesting phenomenon was that the capacities always increased during the cycling process at different current densities.…”

Hierarchical structures are ubiquitous in both animals and plants. The coordination of the hierarchical structures and functions makes living organisms function efficiently. This explains why hierarchical metal oxide (HMO)‐based micro/nanostructures have recently received huge attention as anodes for application in highly efficient lithium‐ion batteries (LIBs). Indeed, hierarchy in such micro/nanostructured HMOs offers high specific surface area, stable structure, short path length, and improved higher packing density to improve the reaction kinetics and Li+/e− transport kinetics, resulting in highly enhanced rate capability and cycling stability for LIBs. This report focuses on the hierarchical design from structural, morphological, porous, and component levels to engineer the HMOs as anodes for LIBs. The advantages of micro/nanostructured HMO‐based on three reaction mechanisms (intercalation/deintercalation, conversion, and alloying/dealloying), important challenges ahead, and future perspectives on designing advanced electrode materials for next‐generation high‐performance LIBs are discussed.

“…Pyridinic N and pyrrolic N will cause the formation of vacancy defects in carbon, which greatly enhance the storage of lithium and the performance of LIBs . The spectrum of C 1s (Figure d) owns three peaks corresponding to C−C (284.8 eV), C≡N (286.2 eV) and O=C−O (288.4 eV), illustrating N element was doped into carbon successfully . For the contrast, there are no peaks of N 1s and C≡N in XPS spectra of TiO 2 /C (Figure e, f).…”

Rapid Synthesis and Good Performance of TiO₂/Nitrogen‐Doped Carbon Spheres as Anode Materials for Lithium Ion Batteries

A facile, efficient and short‐time shearing method was developed to synthesize TiO2 precursor, then followed by calcining in NH3 gas to obtain nitrogen‐doped carbon coated TiO2 (TiO2/N‐C) successfully. Interestingly, the prepared TiO2/N‐C nanospheres were assembled by many tiny nanoparticles (NPs) and possessed rough surface. When used as an anode material, the TiO2/N‐C exhibited reversible specific capacity of 277 mA h g−1 after 220 cycles at the current density of 0.6 C, indicating the superb cycle stability of TiO2/N‐C. And a good rate capability at different current densities was also obtained. The excellent performance of the TiO2/N‐C was due to the nitrogen‐doped carbon and assembly structure, which could enhance the electrical conductivity and buffer the volume expansion during the charge and discharge process. Furthermore, the tiny NPs can short the transportation path of lithium ions and the gaps produced between connective tiny NPs could accommodate the volume change. So, the method of high speed shearing has great potential in synthesizing other anode materials for lithium ion batteries.
