Abstract
Rutile TiO2 is a prospective lithium-ion anode material, which has the advantages of small volume change and excellent cycling performance. The low theoretical capacity and poor conductivity, however, prevent further application. In this work, we proposed a thermochemical cyclization coating strategy and successfully prepared rutile titanium dioxide anode material coated with conductive polymer Polyacrylonitrile (PAN). The coated material has an initial capacity of 246.5 mAh/g and a stable capacity of 125.5 mAh/g after 100 cycles. It is worth noting that this simple and effective coating method will contribute to the further application of rutile TiO2 materials.
