AB - Titanium dioxide (TiO2) is a promising anode material for lithium-ion batteries (LIBs) owing to its low price, excellent cyclingstability, low operating voltage, and environmentally friendly nature. However, owing to their poor electrical and ionicdiffusion, TiO2 anodes show low specific capacity and poor high-rate performance. In this study, in an attempt to improve theelectrical and ionic diffusion properties, we dispersed TiO2 nanoparticles into N- and P-doped carbon nanofibers (N/P-dopedCNF/TiO2) using the hydrothermal, electrospinning, and carbonization processes. The N/P-doped CNF/TiO2 electrode showedhigh specific capacity (311.5 mAh g−1 at 100 mA g−1 after 100 cycles), outstanding high-rate performance (286 mAh g−1 at 2000mA g−1), and excellent ultrafast cycling stability (285 mAh g−1 at 2000 mA g−1 after 500 cycles). The results showed thatdispersing TiO2 nanoparticles into N- and P-doped CNFs is an efficient approach to improve their electrical conductivity,shorten their lithium ion diffusion pathways, and stabilize the electrochemical conditions for ionic diffusion during ultrafastcycling.
