Abstract
Antimony tin alloy (SnSb) has been regarded as a promising anode material for sodium-ion batteries due to its high capacity. However, the rapid capacity decay of SnSb anodes caused by volume changes during repeated cycles must be solved before they can be used in practical batteries. Here, we introduce centrifugally-spun SnSb@rGO@CMF composite anode for sodium-ion batteries, which not only has high sodium storage capability but also maintains its structural integrity after repetitive cycles. SnSb@rGO@CMF composite was prepared by high-speed and cost-effective centrifugal spinning and subsequent heat treatment processes. Electrochemical performance results demonstrated that SnSb@rGO@CMF composite anode had excellent initial reversible capacity (350.3â¯mAhâ¯gâ1), outstanding initial Coulombic efficiency (68.2%), and superior capacity retention (91.1%) over 200 cycles at 50â¯mAâ¯gâ1. Therefore, centrifugally-spun SnSb@rGO@CMF composite has great application prospect as an anode material for sodium-ion batteries.
