Abstract
The performance of TiO2 microcones/CNT composites as an anode material for lithium ion batteries was investigated. TiO2 microcones/CNT composites were prepared by the polarization followed by electrophoretic deposition approaches on anodic TiO2 microcones, which were composed of individual nanofragments resulting in a large surface area where lithium ion can be stored. Compared to pristine TiO2 microcones, TiO2 microcones/CNT composite electrodes showed higher areal capacity with a stable cyclability due to an enhanced electrical and lithium ion conductivity. Furthermore, TiO2 microcones/CNT composite electrodes exhibited good cycle life characteristics and excellent rate retention under a high current density of up to 20 C.
