文摘

A nanostructured binary transition metal oxide, copper ferrite (CuFe₂O₄) is synthesized via polymer-pyrolysis method. The effects of the processing temperature on the particle size and electrochemical performance of the nanostructured CuFe₂O₄ are investigated. The electrochemical results show that the sample synthesized at 700 ¡ãC shows the best cycling performance, retaining a specific capacity of 551.9 mAh g^?#xA0;1 beyond 100 cycles for lithium ion batteries. The electrode has a good rate capacity within the range of 0.2 C-4 C. At the highest rate of 4 C, the reversible capacity of CuFe₂O₄ is about 200 mAh g^?#xA0;1. It is believed that the ternary transition metal oxide CuFe₂O₄ is quite acceptable compared with other high performance nanostructured anode materials.
