Abstract Core-shell Fe3O4-polypyrrole (Fe3O4-PPy) composites are synthesized by etching and polymerization to address the capacity degradation and low Coulombic efficiency (CE) of the Fe3O4 electrodes for lithium storage. When the weight content of Fe3O4 is 60%, a conformal carbon-coated Fe3O4 composite is formed, which can retain a charge capacity of 451 mAh g−1 after 800 cycles at 2 C with a high initial CE of 74.8%. The diffusive and capacitive contribution to the capacity are evulated, demonstating the advantages of the synergistic lithiation of the Fe3O4-PPy electrodes.
