“…Exhilaratingly, the independent Fe 3 O 4 nanoparticles are surrounded by carbon and can be quite well separated, which can effectively prevent their aggregation as an active material and can help to adapt their volume expansion during the cycle. 21 As displayed in Fig. 1j, the particle size of Fe 3 O 4 nanoparticles is about 20 nm surrounded by white lines, and the width of the lattice stripe is about 0.290 nm, corresponding to the (220) crystal plane of Fe 3 O 4 , which is surrounded by amorphous carbon.…”

“…Specific capacity has an upward trend that may be caused by the gradual infiltration of electrolytes over time (Fig. 3e), 6,21 which is responsible for the increase in the capacity of the material. Both The specific capacity decreases over a long cycle at high current density(Fig.…”

“…The C 1s deconvoluted spectrum of GO@Fe 3 O 4 @PDA displayed three peaks at 284.6 and 285.8 and 287.5 eV, which were corresponded to C-C, C-N and C = O and suggested polydopamine was selfpolymerized on the surface of magnetic GO(Fig. 2B) [54]. The N 1s deconvoluted spectrum of GO@Fe 3 O 4 @PDA-N 3 showed three peaks around 398 eV, 399.7 eV, 401.8 eV corresponding to C-N, -N-H, -N=, revealing the azido group was successfully introduced(Fig.…”

“…The N-doped graphene structure of pyrolyzed polydopamine has obvious advantage in electrical conductivity because it can be polymerized under mild conditions, and the pyrolyzed polydopamine exhibits high conductivity similar to that of nitrogen-doped graphene oxides. 16 According to previous studies, coating pyrolyzed polydopamine on the CNF surface can favor improving electrical conductivity. It was reported that by overlaying pyrolyzed polydopamine, the conductivity increased to 630%.…”
