To overcome the problem of poor electrical and lithium-ion conductivity of metal oxide,hybridizing nanostructured metal oxides with multiwalled carbon nanotubes(MWCNTs)conductive network,is fairly favorable for the improvement of electrochemical performance of lithium-ion batteries [1].In this work,the nanocomposites of MWCNTs and ZnFe2O4 hollow spheres were synthesized via in-situ hydrothermal hybridization and subsequent annealing treatment in the argon atmosphere.
