Brookite TiO2 mesocrystals with enhanced lithium-ion intercalation properties.

Brookite TiO2 mesocrystals were synthesized for the first time using amorphous titanate used as a precursor, exhibiting a high rate capability when applied as an anode for lithium-ion batteries. An in situ X-ray diffraction test of lithium intercalation into the brookite TiO2 structure was further investigated and revealed a reversible phase transformation.
