SnO2 PINNING: AN APPROACH TO ENHANCE THE ELECTROCHEMICAL PROPERTIES OF NANOCRYSTALLINE CuFe2O4 FOR LITHIUM-ION BATTERIES

A first attempt to synthesise and explore SnO2 pinned CuFe2O4 material as an anode for lithium-ion batteries was made. The study highlights the approach of exploiting SnO2 pinning to enhance the electrochemical properties of nanocrystalline CuFe2O4 anodes. Virgin CuFe2O4 and SnO2 pinned CuFe2O4 powders were synthesised with 10-30 nm via under a one pot solution combustion method with specific calcination conditions. SnO2 pinning reduces saturation magnetisation and bulk resistance, thereby enhancing the charge-discharge characteristics of native CuFe2O4 anodes significantly in rechargeable lithium cells. 39 refs.
