Abstract

original image

Curled up: TiO2-B nanotubes with two curled layers are successfully prepared by a facile hydrothermal route and subsequent calcination. The two curled layers produce a thin wall, and thus the obtained double-walled structure results in short distances of electron and lithium-ion transport, thereby leading to an improved high-rate performance.
