Abstract

Non-toxic, cheap, nanostructured ternary transition metal oxide CuFeO₂ was synthesised using a simple sol–gel method at different temperatures. The effects of the processing temperature on the particle size and electrochemical performance of the nanostructured CuFeO₂ were investigated. The electrochemical results show that the sample synthesised at 650 °C shows the best cycling performance, retaining a specific capacity of 475 mAh g⁻¹ beyond 100 cycles, with a capacity fading of less than 0.33% per cycle. The electrode also exhibits good rate capability in the range of 0.5C–4C. At the high rate of 4C, the reversible capacity of CuFeO₂ is around 170 mAh g⁻¹. It is believed that the ternary transition metal oxide CuFeO₂ is quite acceptable compared with other high performance nanostructured anode materials.
