“…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. However, the tap density of the mesoporous TiO2 is only 0.714 g cm −3 , which limits its volumetric capacity.…”

“…As one of the most attractive candidates for anode materials of Li-ion batteries, TiO2 has drawn increasing interest [4,[7][8][9][10][11]. It has several remarkable characteristics, including its low cost, environmental non-toxicity, a high operation voltage (suppressing the formation of solid-electrolyte interphase layers and Li dendrites), a small volume change, and a robust structure.…”

“…Thus, electrode materials with a high tap density are needed to improve the volumetric performance of energy-storage devices. Mesoporous materials with pore sizes of 2-50 nm are ideal candidates [4]. They have not only abundant pores, facilitating the entry of electrolytes and the transport of Li ions, but also a high tap density, which improves the volumetric performance.…”

“…One strategy for improving the volumetric performance is to promote the volumetric capacity of the electrode materials [4,5]. Although the nanomaterials used as electrode materials show an impressive gravimetric capacity, they usually have an extremely low tap density [6], inevitably leading to an unsatisfactory volumetric capacity.…”

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.
