摘要

ZnFe2O4, a type of mixed transition metal oxide, is considered as one of the most attractive potential anode materials for LIBs due to its high reversible capacity and satisfactory structural stability. However, the low conductivity and the serious volume exchange during the electrochemical process are still two main issues for ZnFe2O4. In this study, we first designed conductive PANI layer coated hollow ZnFe2O4 nanospheres by micro emulsion polymerization. Two strategies of hollow structure and PANI coating were attempted to relieve expansion and increase conductivity. The results show that the as-designed hollow ZnFe2O4@PANI composites exhibited a large initial specific capacity of 1489.38 mA h g(-1) with the first discharge that is maintained at over 607.3 mA h g(-1) even after 50 charge-discharge cycles.
