VS4/Multi-Walled Carbon Nanotubes Shell-Core Nanoarchitectures with Interfacial V-C bonds for High-Rate Sodium-ion Battery Anode
2021
Abstract VS4/MWCNTs (multi-walled carbon nanotubes) shell-core nanoarchitectures with interfacial V-C bonds are successfully constructed using a facile hydrothermal method. The synergistic effect of shell-core structure and interfacial V-C bond significantly enhances its rate capacity with the specific capacities of 734, 531 and 448 mAh g-1 at 0.1, 0.2 and 1.0 A g-1 after 15, 15 and 100 cycles, respectively, as sodium-ion battery anode. The work opens up new insights for the design and construction of the metal sulfides/carbon composite structure, and their application in energy storage and conversion field.
