Investigation of the effects of the cobalt-doped tin diselenide nanostructures for highperformanceelectrochemical supercapacitors

Supercapacitors and batteries face technical challenges that need to be addressed to meet the growingdemand for clean energy technologies. Also, two-dimensional nanolayered transition metal dichalcogenides (۲DTMDs) have attracted great attention to enhancing capacitive behaviors due to their ultrathin structure, largesurface area, and concurrently "Faradaic" and "double layer" energy storage mechanisms. The maximumcapacity of ۳۱۶.۴ Fg-۱ was obtained at the current density of ۴.۵ A g-۱ for the prepared Co-SnSe۲@NF electrode.Also, this electrode showed very good cyclic stability, so after ۱۳۰۰۰ cycles, it exhibited about ۱۲۴% of its initialcapacitance, which indicates the effect of the cobalt doping to increase the mechanical strength of the tindiselenide nanostructure
