Perovskite-type samarium cobalt oxide adorned hexagonal tungsten sulfide nanocomposites as a high-performance electrode material for symmetric supercapacitors

Innovative solvent-free compound-direct synthesis of defect-rich ultra-thin NiS nanosheets for high-performance supercapacitors

“…6c. The maximum energy density of 71.0 W h kg −1 was achieved when the power density was 229.3 W kg −1 and the maximum power density of 2525.2 W kg −1 at the energy density of 12.2 W h kg −1 , which is obviously higher than those of NiCo 2 O 4 /N-rGO//AC, 29 C/NiCo 2 S 4 //AC, 30 NiMnO 3 /CNT/PANI//AC, 31 Ni 3 S 2 /PNG-10//PNG, 32 CeCoHCF//CeCoHCF, 33 SmCoO 3 /WS 2 /NF//SeCoO 3 /WS 2 /NF 34 and RuO x -MCNF//RuO x -MCNF. 35…”

Novel Design of Perovskite-Structured Neodymium Cobalt Oxide Nanoparticle-Embedded Graphene Oxide Nanocomposites as Efficient Active Materials of Energy Storage Devices

“…Currently, perovskite-type materials have been widely studied in energy storage devices, including solid oxide fuel cells, solar cells, supercapacitors, and batteries, due to their unique thermoelectric, magnetic, and catalytic properties coupled with good thermal and chemical stability and exclusive electronic structure as well as redox properties. − Perovskite structures have the generic formula ABO 3 , which is described as follows: A = rare earth element (lanthanide) and B = transition metal. Furthermore, A is a large cation that is coordinated to 12 oxygen ions and B is a cationic unit smaller that is coordinated to six oxygen ions, respectively .…”
