Hierarchical nanocomposite of carbon-fiber-supported NiCo-based layered double-hydroxide nanosheets decorated with (NiCo)Se2 nanoparticles for high performance energy storage

Hong Jia et al.

Summary: In this study, a fibrous hierarchical nanocomposite composed of carbon microfibers covered with a layer of metal-organic framework derived from nickel-cobalt layered double-hydroxide nanosheets decorated with (NiCo)Se-2 nanoparticles was fabricated using an in-situ self-templated method. The nanocomposite exhibited improved electrical conductivity, high capacity, and structural stability, leading to an impressive capacity of 1394.2 F g(-1) at 1 A g(-1) and high energy and power densities in a hybrid supercapacitor. These results suggest the potential of the hierarchical nanocomposite as a powerful electrode for advanced next-generation supercapacitors.
