SnO2 microfibers were synthesized by using centrifugal spinning technology and were evaluated as the anode in sodium-ion batteries. The as-prepared SnO2 microfibers are composed of interconnected nanoparticles with small interparticle openings. The 1-demensional fibrous morphology, fine particle size, and open pore structure result in reduced electrochemical impedance and enhanced electrochemical performance. The highest capacity achieved is 567mAhg(-1) at 20mAg(-1). At a much higher current density of 640mAg(-1), the microfiber electrode still retains a high capacity of 158mAhg(-1) after 50 cycles. The SnO2 microfibers also demonstrate good rate performance in a current range of 20-640mAg(-1). The results demonstrate that SnO2 microfibers are a potential anode material candidate for sodium-ion batteries and that centrifugal spinning offers a feasible solution for the large-scale production of fibrous electrode materials.
