High-performance supercapacitor based on multi-structural CuS@polypyrrole composites prepared by in situ oxidative polymerization

Heterogeneous NiCo2O4@polypyrrole core/sheath nanowire arrays on Ni foam for high performance supercapacitors

“…Additionally, a broad peak is observed from 2q ¼ 15e30 resulting from the polymer phase, which matches well with the pure PPy (Supporting information Fig. S1) [33,34]. The results of XRD suggest successful polymerization of pyrrole and the formation of NiCo 2 O 4 @PPy nanocomposites.…”

Synthesis of reduced graphene oxide wrapped-copper sulfide hollow spheres as electrode material for supercapacitor

“…However, some defects such as expensive nature of RuO 2 and poor electrical conductivity (10 À5 to 10 À6 S cm À1 ) of MnO 2 have limited their widely application in energy-related fields [8]. Compared with these materials, metal sulfides are abundant and cheap due to the existence of minerals in nature, and most of them are good metallic conductors [9]. Recently, some metal sulfides, such as MoS 2 and CoS, have been investigated as electrode materials for supercapacitors in view of their special structural properties and high theoretical capacities [10,11].…”
