Heterostructure engineering of electrode materials, which is expected to accelerate the ion/electron transport rates driven by a built-in internal electric field at the heterointerface, offers unprecedented promise in improving their cycling stability and rate performance. Herein, carbon nanotubes with Co 9 S 8 /ZnS heterostructures embedded in a N-doped carbon framework (Co 9 S 8 /ZnS@NC) have been rationally designed via an in-situ vapor chemical transformation strategy with the aid of thiophene, which not only acted as carbon source for the growth of carbon nanotubes but also as sulfur source for the sulfurization of metal Zn and Co. Density functional theory (DFT) calculation shows an about 3.24 eV electrostatic potential difference between ZnS and Co 9 S 8 , which results in a strong electrostatic field across the interface that makes electrons transfer from Co 9 S 8 to the ZnS side. As expected, a stable cycling performance with reversible capacity of 411.2 mAh g À 1 at 1000 mA g À 1 after 300 cycles, excellent rate capability (324 mAh g À 1 at 2000 A g À 1 ) and a high percentage of pseudocapacitance contribution (87.5% at 2.2 mv/s) for lithium-ion batteries (LIBs) are achieved. This work provides a possible strategy for designing multicomponent heterostructural materials for application in energy storage and conversion fields.[a] Prof.

“…Hints from the previous reports indicate that rational interface designing could be of great importance for the improvement of conversion reaction kinetics in rechargeable SIBs. Some emerging heterostructures such as Ni 3 S 2 /MoS 2 , Sb 2 S 3 /SnS 2 and Sb 2 S 3 /MoS 2 have demonstrated outstanding electrochemical performance, which is difficult to realize in a signal material system [31][32][33][34][35][36]. However, the detailed synergistic effects and heterointerface properties are rarely revealed.…”

Improving the cycling stability of metal sulfide-based anode materials at high rate is of great significance for advanced sodium ion batteries. However, the sluggish reaction kinetics is a big obstacle for the development of high-performance sodium storage electrodes. Herein, we have rationally engineered the heterointerface by designing the Fe1−xS/MoS2 heterostructure with abundant “ion reservoir” to endow the electrode with excellent cycling stability and rate capability, which is proved by a series of in and ex situ electrochemical investigations. Density functional theory calculations further reveal that the heterointerface greatly decreases sodium ion diffusion barrier and facilitates charge-transfer kinetics. Our present findings not only provide a deep analysis on the correlation between the structure and performance, but also draw inspiration for rational heterointerface engineering toward the next-generation high-performance energy storage devices.

“…Interface engineering has been regarded as a powerful method to construct robust composites for multiple functions and applications [14,15] . The scientists have synthesized some composites with stable structure and abundant anchor sites, such as TiO 2 -graphene [16] , MnO-graphene [17] , and some other composite electrodes [18,19] , through constructing robust coupling interface between different components. However, constructing a robust coupling interface between MoS 2 and graphene is still a great challenge, due to the difficulty in forming stable Mo-C or S-C bonds.…”
