Abstract
A facile electrophoretic deposition technique is developed to prepare composite films of ZnFe2O4 (ZFO) and different carbonaceous materials such as carbon nanotubes and reduced graphene oxide for stable lithium-ion battery anode. The as-deposited films exhibit superior cycling stability with no capacity fade and good rate capability. High reversible capacities of 840 and 870 mAhg−1 were obtained after 100 cycles at 0.5 Ag−1 for ZFO-CNT and ZFO-RGO electrodes, respectively. The contribution of capacitive charge storage in the electrochemical performance is analyzed.
