Construction of heterogeneous interface structures of a cobalt/iron sulfide derived from a binary metal–organic framework for ultra-stable sodium-ion storage
Jiatong Han, Zihan Wang, Chengmei Li, Ping Bai, Qi Liu, Hengrui Qiu, Yongqiang Zhang, Wenxiu HeThis work presents a novel CoS/FeS heterostructure encapsulated in a carbon matrix that enhances the electrochemical kinetics and stability of sodium-ion battery anodes. The study shows a general MOF-mediated heterostructure design strategy for developing high-performance energy storage materials.
