Titanium dioxide@titanium nitride nanowires on carbon cloth with remarkable rate capability for flexible lithium-ion batteries

Flexible lithium-ion batteries have attracted tremendous attention as a promising power source in the growing field of flexible electronic devices. In this article, we report a simple and binder free for the synthesis of TiO2@TiN nanowires on carbon cloth by hydrothermal method and annealing. This method is highly effective in improving the rate capability of TiO2 with discharge capacity of 136 mAh g(-1) at high current rate to 30C. The TiO2@TiN nanowires on carbon cloth also show remarkable cyclic performance retaining 84% of the initial capacity (240 mAh g(-1)) after 650 cycles at 10C. High performance full flexible battery device based on TiO2@TiN nanowires/carbon cloth composite anode and LiCoO2 cathode exhibiting superior capacity retention with high discharge capacities of 227 mAh g(-1) and 222 mAh g(-1) at the flat and 90 bending position respectively during 30 cycles at 1C.
