Abstract

Abstract A direct electrodeposition technique for very high quality Cu nanotube arrays and subsequent conversion of the deposited Cu into Cu2O has been developed. The Cu2O nanotube arrays have high capacity, high cyclability and high rate capability. The cycling performance of Cu2O nanotubes show a high level of structural integrity with capacity retention even after 94 cycles when cycled at 1.67 mA/cm2. The outstanding electrochemical performance of the Cu2O nanotubes comes from high surface area, easy infiltration of ...
