“…For example, Yu et al [12] reported rutile TiO2 submicroboxes with superior Li-storage performance but a TiO2 tap density of only 0.44 g cm −3 . The tap density of TiO2-(B) was improved by using large starting materials [13], but the value was only 0.67 g cm −3 . Saravanan et al [4] reported mesoporous TiO2 with impressive capacities nearly five times better than those of commercially available TiO2 nanopowders.…”

High-tap density electrode materials are greatly desired for Li-ion batteries with high volumetric capacities to fulfill the growing demands of electric vehicles and portable smart devices. TiO2, which is one of the most attractive anode materials, is limited in their application for Li-ion batteries because of its low tap density (usually <1 g cm −3 ) and volumetric capacity. Herein, we report uniform mesoporous TiO2 submicrospheres with a tap density as high as 1.62 g cm −3 as a promising anode material. Even with a high mass loading of 24 mg cm −2 , the TiO2 submicrospheres have impressive volumetric capacities that are more than double those of their counterparts. Moreover, they can be synthesized with 100% yield and within a reaction time of~6 h by optimizing the experimental conditions and formation mechanism, exhibiting potential for large-scale production for industrial applications. Other mesoporous anode materials, i.e., hightap density mesoporous Li4Ti5O12 submicrospheres, are fabricated using the generalized method. We believe that our work provides a significant reference for the industrial production of mesoporous materials for Li-ion batteries with a high volumetric performance.

Carbon-modified ramsdellite titanium dioxide, TiO 2 (R), was prepared without using metallic Ti powder, and its charge and discharge properties was investigated as an anode of lithium ion batteries. Carbon sources (citric acid and multi-walled carbon nanotubes) were added in the calcination process to obtain a LiTi 2 O 4 precursor. The carbon addition was indispensable to obtain stoichiometric LiTi 2 O 4 as a precursor and the resulting Li + -free TiO 2 (R). The carbon-modified TiO 2 (R) had a round shape and a smaller particle size of 0.5-1.5 µm. The discharge capacity and rate-capability were improved by carbon modification due to an enhancement of the electronic conductivity and a reduction of the lithium-ion diffusion path.

Titanium dioxide of bronze phase (TiO2(B)) has attracted considerable attention as a promising alternative lithium/sodium‐ion battery anode due to its excellent operation safety, good reversible capacity, and environmental friendliness. However, several intrinsic critical drawbacks, including moderate electrochemical kinetics and unsatisfactory long cyclic stability, significantly limit its practical applications. It is crucial to develop reliable strategies to resolve these issues to advance the TiO2(B) based materials into practical applications in lithium/sodium‐ion batteries. In this review, both the theoretical and experimental investigations on the TiO2(B) based materials over the last few decades are chronically elaborated. Insights on the general and detailed evolution trends of the research on TiO2(B) anodes are provided. The review also points to future directions for the TiO2(B) anode research to advance the practical application of TiO2(B) anodes.
