3D core–shell binder-free CoMoO4@NiCo2S4@NF with excellent stability and high capacitance was developed as a positive electrode material for supercapacitors.
Facile interfacial growth of MnO2 nanoparticles on carbon nanofibers (MnO2/CNF) and the application of this material as a high-performance positive electrode material in asymmetric supercapacitors are presented.
