| Abstract | Metal selenides with high conductivity are emerging as potential candidates for electrode materials in the realm of supercapacitors. In this context, we introduce the FeCoSe2@NiCoLDH hollow sphere, termed FCS@NCLDHHS, crafted using a straightforward solvothermal method. This sphere is structured by layering two-dimensional NiCoLDH nanosheets onto FeCoSe2 hollow spheres. Merging NiCoLDH with FeCoSe2 results in heterostructures that significantly enhance supercapacitive behavior. Moreover, the external NiCoLDH nanosheets play a pivotal role in preventing the corrosion and degradation of the FeCoSe2 hollow structure during extended stability evaluations. Owing to these advantages, the FCS@NCLDHHS electrode showcases impressive metrics: a specific capacity of 1305C g−1, rate performance of 80.25 % at 25 A g−1, and cyclic longevity retaining 94.45 % capacity. Furthermore, a device ((−)activated carbon (AC)//(+)FCS@NCLDHHS), constructed using FCS@NCLDHHS (cathode) and AC (anode) delivers an energy density (ED) of 55.45 W h k−1 at a power density (PD) of 803.65 W kg−1 and maintains 88.25 % of its original capacity. This research potentially paves the way for merging two efficient materials to create a multifaceted hollow structure with enhanced electrochemical attributes. |
