| 英文摘要 | SnO2 has been considered as an attractive anode material for lithium-ion batteries. However, its poor cycling life due to dramatic volume change during cycling processes hinders its commercial application. Herein, a facile approach has been proposed to coat conductive polypyrrole layers on every shell of hierarchical SnO2 spheres with a hollow multishelled structure (SnO2@Ppy HoMS). The Ppy layers as a framework on every SnO2 shell can both improve the conductivity and maintain the structural integrity during charging-discharging processes. The composite with multishelled SnO2 as active material can enhance the energy density of the battery, and the voids between shells accommodate the volume expansion. Thanks to these merits, the SnO2@Ppy HoMS anode delivers excellent electrochemical performance, achieving impressive cycling stability of 782 mAh g(-1) after 650 cycles at a current density of 0.25?degrees C and an ultra-rapid and stable charge-discharge performance of 580 mAh g(-1) at 4C for 5000th cycles. |
