A facile route was established to synthesize hierarchically structured high specific surface area (122 m 2 g −1 ) TiO 2 microspheres (diameter: 0.5–1 μm). In a heated Teflon‐coated stainless‐steel autoclave, titanium tetrabutoxide Ti(OBu) 4 , arginine, and absolute ethanol were reacted via the solvothermal reaction to generate the TiO 2 precursor. The as‐formed precursor solid was further processed at 673 K under air to generate the TiO 2 microspheres of nanosheets (thickness: 18 nm). The products were examined as potential anode materials for Li‐ion and Na‐ion batteries. After 100 cycles at 0.1 C (1C=335 mA h g −1 ), the assembled batteries showed respectable specific capacity 241 mA h g −1 and 145 mA h g −1 for Li‐ion and Na‐ion batteries, respectively.
