Fabrication of PANI-coated ZnFe2O4 nanofibers with enhanced electrochemical performance for energy storage

We successfully combined electrospinning with in situ polymerization methods to synthesize the PANI-coated ZnFe2O4 nanofibers which possessed the abundant pore structure. The lithium storage properties of PANI-coated ZnFe2O4 nanofibers as anode materials for lithium-ion batteries have been discussed for the first time. Electrochemical property demonstrated that 15% PANI incorporated ZnFe2O4 composite nanofibers (ZP-15) possessed much higher reversible capacity and cycling stability than that of pure ZnFe2O4 nanofibers, 10% PANI incorporated ZnFe2O4 composite nanofibers (ZP-10) and 20% PANI incorporated ZnFe2O4 composite nanofibers (ZP-20). Moreover, the 15% PANI incorporated ZnFe2O4 composite nanofibers (ZP-15) electrode also exhibited high capacity at higher charge/discharge rate.252
