Highly ordered ZnMnO3 nanotube arrays from a “self-sacrificial” ZnO template as high-performance electrodes for lithium ion batteries

Abstract

Highly ordered ZnMnO₃ nanotube arrays (ZnMnO₃ NTAs) are prepared by an electro-deposition strategy in the presence of “self-sacrificial” ZnO templates. The ZnMnO₃ NTA electrode exhibits excellent cycling performance (857.5 mA h g⁻¹ after 200 cycles at 500 mA g⁻¹) and superior rate capability (208.3 mA h g⁻¹ after 200 cycles at 5000 mA g⁻¹). The excellent electrochemical performance should be mainly attributed to its “mixed” chemical compositions and hollow nanotube array morphologies.
