Abstract Defective ZnFe2O4/graphene (D-ZFO/G) composites are synthesized by a novel laser irradiation route. D-ZFO/G composites with unique architecture satisfy all the kinetic requirements for a desirable electrode material. Particularly, oxygen vacancies lied in D-ZFO/G provide abundant active sites for electrochemical reactions and enhance the intrinsic conductivity of ZFO for fast electron transport in D-ZFO/G electrode. D-ZFO/G composites then achieve a large specific charge of 474 C g−1 at 1 A g−1, high rate capability (95.8% at 10 A g−1), and excellent cycle life (98.9% capacity retention after 20,000 cycles).
