High performance binder-free quaternary composite CuO/Cu/TiO2 nanotube/Ti (CuO/Cu/TiO2NT/Ti) electrode for lithium ion battery was designed and synthesized via anodization, electrodeposition and thermal oxidation at 450 degrees C in the air. The as-prepared binder-free quaternary composite CuO/Cu/TiO2NT/Ti electrode was studied in terms of XRD, XPS, SEM, EDX, galvanostatic charge/discharge, cycle stability, cyclic voltammetry (CV) and AC impedance. As expected, the binder-free quaternary composite CuO/Cu/TiO2NT/Ti electrode displayed much higher discharge capacity, cycle stability, Li+ diffusion coefficient than bare TiO2NT/Ti electrode. High Li-storage activity of CuO, high conductivity of Cu and the synergy effect among various components should be responsible for improved electrochemical performances. Additionally, binder free combination of the various components may also contribute into the modifications due to the exclusion of negative effect of polymer binder.
