This paper reports surface modification of graphite anodes using carbon coated Fe3O4 nanospindles (C-Fe3O4 NSs) with the goal of improving graphite electrode capacity and decreasing graphite degradation and irreversible capacity. A unique novel coating method based on magnetic fields was developed for coating prefabricated graphite electrodes containing conductive additives and binder. A thin layer of synthesized C-Fe3O4 NSs was coated on the surface of graphite anodes to prevent direct contact of graphite's surface and electrolyte. The results indicate that C-Fe3O4 coating decreases growth of solid electrolyte interface (SEI) film on the surface of graphite. The C-Fe3O4 coating increases the initial discharge capacity of graphite anodes from 325 to 414 mAh g(-1) and the initial Coulombic efficiency from 72 to 79%. Moreover, C-Fe3O4 coated electrodes deliver an improved reversible capacity of 240 mAh g(-1) and Columbic efficiency of 99% after 40 cycles, whereas these values were 148 mAh g(-1) and 97% for bare graphite. However, the impedance analysis indicates more resistance in case of C-Fe3O4 coated graphite, which is due to the low ionic conductivity of Fe3O4 compared to graphite. Graphic abstract
