Abstract

Light fostered supercapacitor performance introduces a new realm in the field of smart energy storage applications. Transition metal dichalcogenides (TMDC) with direct band gap are intriguing candidates for developing light...

A Review: Ion Transport of Two-Dimensional Materials in Novel Technologies from Macro to Nanoscopic Perspectives

“…These additional charges increase the accumulation of electrolyte ions at the working electrode, leading to an increase in capacitance (Figure 14a). The process is reversible, with a 1.5-fold capacitance enhancement from 17.9 F cm −3 to 29.8 F cm −3 [125]. However, macroscale is a factor of this supercapacitor.…”

“…In addition, because of the microsupercapacitor's sensitivity to UV light, it can be employed as a photodetector for visible/blind UV detection, including the detection of fire and missile plume [120]. Alternatively, under light illumination, the generation of electron-hole pairs in semiconducting materials could be used as a mechanism for capacitance modulation [125]. A semiconductor is widely employed as a light-absorbing material in photodetectors, where its long cut-off wavelength is determined by the energy gap between conduction and valence bands [126].…”

“…This can be attributed to the direct bandgap, the high quantum efficiency, strong light absorption by the multilayer ReS 2 and the high carrier mobility of graphene [128]. A modulation of capacitance based on that mechanism, namely the generation of electron-hole pairs under light illumination, has been demonstrated by Arya et al [125]. Multiple layers of ReS 2 were grown on stainless steel using the chemical vapor deposition (CVD) method to serve as a working electrode.…”

Reticulated TiO2-Modified Carbon Fiber Enabling as a Supercapacitor Electrode Material for Photoelectric Synergistic Charge Storage

“…DOS was often expressed as the number of electrons per unit energy range. 77 Under the stimulation of light, a mass of electrons in the valence band could jump into the conduction band to facilitate charge transfer, 78 which was beneficial to the EDLC behavior and could enhance the capacitance performance of TiO 2 /CF.…”

Electrochemical performance of transition metal based CoB2O4 (B = Co and Fe) oxides as an electrode material for energy storage devices

“…The hybrid capacitors are the more efficient of the three ECCs because they use both electrostatic and capacitive-faradaic mechanisms to collect higher charge than the other two. [8][9][10] In supercapacitor devices, all energy storage takes place between the electrode-electrolyte interfaces, including electron and ion transport. 11 The structure and morphology of the electrode material play a key role in electrochemical energy storage systems.…”
