Abstract

The electrochemical aluminum storage of anatase TiO₂ nanotube arrays in AlCl₃ aqueous solution is investigated. It is firstly demonstrated that aluminum ions can be reversibly inserted/extracted into/from anatase TiO₂ nanotube arrays in AlCl₃ aqueous solution due to the small radius steric effect of aluminum ions, indicating a potential application in aluminum ion batteries.
