Abstract

Li_3.33Cu_1.005Ti_4.665O₁₂/CuO was fabricated via a one-step solid-state reaction. Li_3.33Cu_1.005Ti_4.665O₁₂ with the P4₃32 space group shows enhanced electronic conductivity and Li⁺ ion diffusion coefficient. The Cu particles reduced from CuO during the first lithiation process benefit the electrical conduction between Li_3.33Cu_1.005Ti_4.665O₁₂ particles. Consequently, Li_3.33Cu_1.005Ti_4.665O₁₂/CuO exhibits a small potential hysteresis and high rate performance.
