Synthesis and Electrochemical Performance of Nano-sized CuO/TiO2 for Lithium-ion Batteries

Abstract

Abstract CuO/TiO2 nanopowder was successfully synthesised by precipitation method. XRD, SEM and galvanostatic testing were applied to study the crystal structure and electrochemical performance of CuO/TiO2. The results showed that the prepared sample was highly-crystalline and exhibited high capacities and well cycle stabilities. The initial discharge capacity of CuO/TiO2 reached 566.5 mAh/g, and retained at 375.9 mAh/g after 20 cycles at 0.1C-rate. It is implied that CuO/TiO2 nanopowder prepared by precipitation method coulde be used as an anode material for lithium-ion batteries.
