Coupling of ReS2 nanosheet arrays with hollow NiCoS4 nanocubes enables ultrafast Na+ diffusion kinetics and super Na+ storage of a NiCoS4@ReS2 heterostructure

In this paper, NiCoS 4 @ReS 2 heterostructure has been successfully constructed by anchoring ReS 2 nanosheet arrays on hollow NiCoS 4 nanocubes, which demonstrated outstanding rate capability and ultra-stable cycling performance for SIBs.
