MOF-derived N,S Co-doped carbon matrix-encapsulated Cu2S nanoparticles as high-performance lithium-ion battery anodes: a joint theoretical and experimental study

A MOF-derived Cu 2 S@NSC hybrid in which ultrathin Cu 2 S nanoparticles are encapsulated in a N,S co-doped carbon matrix was developed, which possesses excellent electrochemical properties serving as a lithium-ion battery anode.
