Metal selenides (MSes) are increasingly recognized for their robust redox activities and notable conductivity, positioning them as promising materials advanced energy-storage applications. Nonetheless, practical utilization is often hampered by challenges, such poor cycle life limited rate capabilities. In this study, we address these issues integrating MSes with reduced graphene oxide (RGO) to construct a nanostructured electrode enhanced performance characteristics. Specifically, developed binder-free comprising trimetallic Co–Mn–Fe selenide nanoflowers encapsulated within an RGO matrix on nickel foam (CMFS-RGO/NF), which tailored use in hybrid supercapacitors. This innovative architecture offers several advantages: the CMFS facilitate swift ion diffusion provide abundant electroactive sites, while wrapping enhances electrical prevents aggregation of nanoflowers, maintains structural integrity during extended cycling. The resultant CMFS-RGO/NF demonstrates superior electrochemical efficiency, achieving capacity 1112.5 C/g at 1 A/g, excellent 79.4% retention 25 fantastic lastingness 94.6%. Further, when configured into apparatus activated carbon (AC) (CMFS-RGO/NF//AC), exhibits exceptional behavior, showcasing energy density (Eden) 65 Wh kg–1 power (Pden) 802.5 W remarkable 91%. These results underscore potential our fabrication strategy, leveraging RGO-encapsulated boost efficiency supercapacitors, thereby providing scalable effective approach developing next-generation systems.
