【 摘 要 】

tsFe1−xS/MoS2 heterostructure with abundant “ion reservoir” interfaces is designed to reduce sodium ion diffusion barrier and facilitate charge-transfer kinetics, thus endowing the electrode with excellent cycling stability and rate capability.The in-depth analysis on the dynamic relationship between heterointerface and sodium storage performance carves a new path for interface engineering toward the next-generation high-performance energy storage devices.
