Abstract:Sb and Sb2O3 are attractive anode materials for sodium ions batteries due to their relatively low cost and high theoretical capacity. However, the poor cycling stability caused by the serious...
“…The Sb 2 O 3 /N-GNR nanocomposite showed a homogeneous distribution of Sb 2 O 3 nanoparticles on N-GNR, leading to a good rate capability at a current density between 0.1 and 5 A g À1 along with excellent cycling performance under continuous charge/discharge. It delivered a reversible specic capacity of 642 mA h g À1 aer 100 cycles at 0.1 A g À1 , which is signicantly higher than that reported by Li et al 28 Without N-doping, the value obtained for the control sample was 535 mA h g À1 under similar conditions. Moreover, Sb 2 O 3 /N-GNR exhibited a stable cycle performance of 405 mA h g À1 aer 500 cycles at 5 A g À1 , demonstrating that upon N-doping of GNR the enhancement of Na storage kinetics is achieved.…”

“…26 Great progress has been made to further improve the anode materials for SIBs by combining the merits of doped-carbon nanostructures with conversion-alloying type oxides and chalcogenides (Sn, Sb and Ge). [27][28][29][30] Especially, Sb 2 O 3 has demonstrated appropriate electrochemical performance in SIBs due to its high reactivity with Na ions, i.e., Sb 2 O 3 reacts with 10 sodium ions per mole, delivering a theoretical specic capacity 1103 mA h g À1 . 27 Recently, Li et al 28 reported a Sb/Sb 2 O 3 nanoparticles anchored on 1D N-doped carbon nanober membranes synthesized by electrospinning method and carbon thermal reduction.…”

A hybrid nanocomposite of Sb2O3 nanoparticles anchored on N-doped graphene nanoribbons is used as anode in SIBs. These hybrid electrodes demonstrate a high charge transfer and improved microstructure, facilitating the Na+ diffusion in the electrode.
