Electrochemical performance of amorphous and anatase TiO2 nanotube array-based anodes fabricated by atomic layer deposition

摘要: AbstractAtomic layer deposition onto highly porous anodic aluminium oxide templates was used to fabricate the arrays of TiO2 nanotubes. The as-prepared nanotubes were amorphous and subsequently transformed crystalline phase, anatase, by thermal annealing at temperature 400–500 °C. These nanotube for Li-ion storage as anode materials. A comparative study electrochemical performance anatase nanotube-array-based anodes has been presented. Amorphous showed very high irreversible capacity compared ones. Reversible ∼177 mAh/g achieved from anode, which close maximum obtainable capacity, known theoretical bulk phase reported.
