Centrifugally spun TiO2/C composite fibers prepared from TiS2/PAN precursor fibers as binder-free anodes for LIBS
Abstract
<p>TiO<sub>2</sub>/carbon composite-fiber anodes for lithium ion batteries were prepared through the centrifugal spinning of TiS<sub>2</sub>/polyacrylonitrile (PAN) precursor fibers and subsequent thermal treatment. The TiS<sub>2</sub>/PAN precursor solutions were prepared by mixing TiS<sub>2</sub> nanoparticles (a 2-D layered structure) with PAN in N, N-dimethylformamide (DMF). The thermal treatment of the TiS<sub>2</sub> in the centrifugally spun PAN fibers resulted in TiO<sub>2</sub>/carbon composite fibers. The structure of TiO<sub>2</sub> nanoparticles embedded in the carbon-fiber matrix synthesized from the TiS<sub>2</sub> starting material may accommodate high amounts of Li ions. The TiO<sub>2</sub>/C structure may lead to increased specific capacity, improved stability, and enhanced electrochemical performance of the TiO<sub>2</sub>/C composite electrode after prolonged charge/discharge cycles. The TiO<sub>2</sub>/C composite-fiber anode delivered discharge and charge capacities at the first cycle of 683 mAhg<sup>−1</sup> and 356 mAhg<sup>−1</sup>, respectively, with a reversible charge capacity of 290 mAhg<sup>−1</sup> after 100 cycles at a current density of 100 mAg<sup>−1</sup>. The TiO<sub>2</sub>/C composite fibers showed an improvement in the rate performance at higher current densities compared to the graphite anode alone.</p>
