Abstract:

Corrugated SnO2 was prepared by an effective template using cotton fibers which were sacrificed during preparation. The as-prepared SnO2 samples were characterized by XRD, SEM, TEM, CV, galvanostatical method and EIS. The results show that the corrugated SnO2 is composed of nanopaticles with size of 16-21 nm. The as-obtained corrugated SnO2 electrodes can deliver a discharge capacity of 614 mAh/g at current density of 70 mA/g after 50 cycles. Even at the current density of 3 A/g the products can still deliver a high reversible discharge capacity of 405 mAh/g. As lithium storage materials, the corrugated SnO2 shows stable cyclability and good rate capability.
