Abstract
TiO2(B) nanowires have shown excellent capacitance and energy density with a very low charge transfer resistance in 80-μm thick lithium ion capacitor electrodes. Nanowires hydrogenated by heat treatment at 500°C showed improved Li ion diffusion and an increase in capacitance from 148 to 194F/g as well as energy density from 23 to 30Wh/kg. Hydrogenation of oxides as a way to improve their capacitance is critically discussed.
•Hydrothermally synthesized TiO2 (B) nanowires were investigated as an anode material for Li ion capacitors.•The effect of hydrogenation of the synthesized nanowires on the electrochemical performance is critically discussed.•As-synthesized TiO2 (B) nanowires exhibited a high capacitance of 148F/g, which increased to 194F/g after hydrogenation.
