Controllable Synthesis of TiO₂@Fe₂O₃ Core-Shell Nanotube Arrays with Double-Wall Coating as Superb Lithium-Ion Battery Anodes.

ABSTRACT: Highlighted by the safe operation and stable performances, titanium oxides (TiO₂) are deemed as promising candidates for next generation lithium-ion batteries (LIBs). However, the pervasively low capacity is casting shadow on desirable electrochemical behaviors and obscuring their practical applications. In this work, we reported a unique template-assisted and two-step atomic layer deposition (ALD) method to achieve TiO₂@Fe₂O₃ core-shell nanotube arrays with hollow interior and double-wall coating. The as-prepared architecture combines both merits of the high specific capacity of Fe₂O₃ and structural stability of TiO₂ backbone. Owing to the nanotubular structural advantages integrating facile strain relaxation as
