Hollow nanostructures of metal oxides as emerging electrode materials for high performance supercapacitors

Abstract

Comparative study of TMO based hollow and solid nanostructures for supercapacitor applications.

Hierarchical NaFePO4 nanostructures in combination with an optimized carbon-based electrode to achieve advanced aqueous Na-ion supercapacitors

“…Hollow NaFePO 4 was synthesized by a one-pot hydrothermal facile route. 15 Detailed synthesis procedures for obtaining materials used in this study are discussed in the ESI. † 16,17 Electrode preparation and characterization Slurries were prepared using active material, polyvinylidene uoride-co-hexauoropropylene (PVDF) binder in acetone (for carbon structures), and N-methyl-2-pyrrolidone (for NaFePO 4 ) as a mixing media.…”

Zeolitic imidazolate framework (ZIF)-derived porous carbon materials for supercapacitors: an overview

“…In assessing the deliverable efficiency of a supercapacitor for real-life applications, determining its energy and power densities is crucial. Cyclic voltammetry (CV) and charge-discharge (CD) techniques can determine both energy and power densities, which can be determined from the equations shown below : 8,[23][24][25][26][27] The specic capacitance (C, F g À1 ) of the device can be calculated using cyclic voltammetry:…”

Superior supercapacitive performance of Cu2MnSnS4 asymmetric devices

“…Metal sulfides have many redox reactions to form good quality SCs with battery type electrode materials and they are considered as positive electrode materials. As a result of the device they exhibit extended potential window and high energy density than conventional supercapacitors [6][7][8][9][10].…”
