Realizing remarkable sodium storage performance of a Sn-based anode material with an oxide-alloy intergrowth structure
文献摘要：
As a promising anode for sodium-ion batteries(SIBs),the performance of SnO2 is still limited by inferior electronic conductivity and large volume change.To address this issue,herein,the intergrowth structured SnO2/CoSn2@C nanocomposite has been fabricated by a two-step process combining hydrothermal synthesis with carbon coating.As an anode for SIBs,the SnO2/CoSn2@C nanocomposite displays a high charge capacity of 573 mAh·g-1 at 0.05 A·g-1 with a capacity retention ratio of 80％over 100 cycles.Even at 5 A·g-1,a reversible charge capacity of 200 mAh·g-1 can be remained.The superior performance can be ascribed to the oxide-alloy intergrowth structure of the SnO2/CoSn2@C nanocomposite,achieving high capacities and remarkable rate performance,and the synergistic effects of Co nanoparticles induced by dealloying process and carbon network to maintain structural integrity and improve electrical contact.This work demonstrates the promising application of the SnO2/CoSn2@C nanocom-posite in the high-performance SIBs.
