| Abstract Scope |
The increasing need for renewable energy storage has spurred the development of energy-efficient supercapacitors. But their use can be constrained by insufficient energy storage capacity. To overcome this limitation, we present a novel design of CuTe-CoTe/NiCoSe2 core-shell nanomaterials as new pseudocapacitive electrodes. Here, the metallic core of CuTe-CoTe ensures efficient electron transfer, and the in situ formed NiCoSe2 shell offers a large number of electroactive sites for charge storage. This unique structure exhibits an open, interconnected mesoporous structure, enabling fast diffusion and transport of electrolyte ions. The combined effect of fast charge transfer and ion kinetics leads to a high specific capacitance of 870 Fg-1 in the three-electrode configuration. Moreover, the symmetric device delivers 586 Fg-1, 40 Whkg⁻¹ energy density and 352 Wkg-1 power density, showing great promise for high-performance energy storage. |
