Abstract

Ti nanowire arrays (NAs) prepared by a facile and template-free hydrothermal method were used as three-dimensional (3D) current collectors for the electrodeposition of MnO₂. The resulting Ti@MnO₂ NAs exhibit remarkable electrochemical behavior with high specific capacitance, good rate performance and desired cycling stability.
