Metal-organic frameworks as highly efficient electrodes for long cycling stability supercapacitors

In situ synthesis of nanostructured Fe3O4@TiO2 composite grown on activated carbon cloth as a binder-free electrode for high performance supercapacitors

“…The specific capacitance is calculated from GCD according to the following equation: 28 where C s (mF cm −2 ) is the areal capacitance, I (A) represent the discharge current, s (cm −2 ), Δ V (V) and Δ t (s) represent the area of the electrode, the potential drop during discharge and the total discharge time, respectively.…”

Advances in pseudocapacitive and battery-like electrode materials for high performance supercapacitors

“…In the last few years, MOF-derived transition metal oxides have grown considerable attention among material scientists all over the world. 67,[297][298][299][300][301][302][303][304][305][306][307][308] For SC applications, MOFs have been regarded as potential candidates because of their porous network-like structure facilitating electron and ion transport, controlled pore size-distribution, high thermal conductivity, and well-ordered crystalline orientation. However, only a few MOFs have been directly applied as SC electrodes.…”

Electrostatic flocking MnO 2 nanofiber electrode for long cycling stability supercapacitors

“…The cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were obtained by a electrochemical workstation (CHI 660E, Shanhai, china).The galvanostatic charge-discharge curves (GCD) was tested on charge-discharge equipment (CT2001A,Wuhan, China). The specific capacitance of electrode was obtained from the GCD curves according to the following Equation (1). The energy density (E cell , Wh kg À1 ) and power density (P cell , mW kg À1 ) were calculated by the Equations ( 2) and (3).…”

“…Supercapacitor has been attracting lots of attentions due to be long cycling life and high power density. 1 Generally, the performance of supercapacitor is mainly determined by the properties and structure of their electrodes. 2 As well-known, the electrode is mainly composed of active materials and metal current collector.…”
