Antimony nanoparticles anchored on interconnected carbon nanofibers networks as advanced anode material for sodium-ion batteries

Interconnected carbon nanofibers networks (ICNNs) prepared through the carbonization of polypyrrole (PPy) precursor are employed to anchor Sb nanoparticles. The as-obtained Sb/ICNNs composite is applied as anode material for sodium-ion batteries (SIBs), delivering excellent cycle stability and rate performance.358
