One-step construction of Ni2S-coated graphene nanosheets with flower-like architecture as binder-free electrode for efficient supercapacitor applications
“…Ni 2 S coated rGO on Ni foam exhibits a surface capacitance of 3.95 F cm −2 and the capacitance remains 55.5% after 5000 cycles. 35 NiS nanoflakes embedded in carbon fibers show a specific capacitance of 1691.1 F g −1 at 1 A g −1 . 19 The NiS 2 /GO composite shows a specific capacitance of 1020 F g −1 at 1 A g −1 .…”
Doping of metal atoms into the metal sulfide lattice is a promising strategy to enhance the intrinsic ion/electron transport capability and thus the electrochemical properties. The iron dopped nickel sulfides...

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.
