摘要
A direct electrodeposition technique for Cu nanotube array fabrication and the subsequent conversion of the deposited Cu into Cu2O was developed. The Cu2O nanotube arrays showed high capacity, cyclability, and rate capability. The cycling performance of the Cu2O nanotubes showed a high level of structural integrity with capacity retention even after 94 cycles when cycled at 1C to 3C rates. The enhanced electrochemical performance of the Cu2O nanotubes came from a high surface area, electrolyte access, high electrical conductivity of Cu core support, and structural integrity of the oxide shell active material.
