Abstract:The poor conductivity and large volume swelling of transition-metal sulfides are still big challenges to overcome for highperformance energy storage. Herein, the flexibility of MOF precursors offers remarkable versatility in tailoring the chemical composition of NiCo sulfides with a highly desirable porous structure, and then dualcarbon-confined (Ni 0.28 Co 0.72 ) 1−x S nanoparticles are designed, in which an inner sulfur-doped porous carbon (SC) matrix (derived from the organic ligands of metal−organic framew… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
