静电纺丝制备三明治结构的C@MoS2/C@C用于高性能钠离子电池
Sandwich-Structured C@MoS2/C@C Prepared by Electrospinning for High-Performance Sodium-Ion Batteries
摘要
Abstract
In recent years,sodium-ion batteries have become a hot research topic due to the abundance and cost-effectiveness of sodi-um resources.Nevertheless,the large radius of Na+may lead to the structural instability of the material,which affects the performance of sodium-ion batteries(SIBs).MoS2,as an anode material with high theoretical specific capacity,can provide more charge storage space.However,the intercalation/deintercalation processes of Na+in MoS2 may cause large volume changes,which may damage the structure and thus shorten the cycle life.In this study,C@MoS2/C@C complexes with a sandwich structure were successfully prepared by alternating electrospinning technique as an anode material for SIBs.The electrode maintains a discharge specific capacity of 270.1 mAh/g after 100 cycles at 0.1 A/g,showing excellent capacity retention and good cycling stability.In addition,kinetic analyses reveal that C@MoS2/C@C electrode has remarkable capacitive charge storage properties.This work provides new perspectives and methods to improve the stability of MoS2 for SIBs.关键词
