Boron cross-linked graphene oxide/polyvinyl alcohol nanocomposite gel electrolyte for flexible solid-state electric double layer capacitor with high performance

Ionic liquid-based polymer gel electrolytes for symmetrical solid-state electrical double layer capacitor operated at different operating voltages

“…Electrical double layer capacitors (EDLCs) are energy storage devices that are attracting the interests of researchers due to their high power density and long cycle life [1][2][3]. This device works on the reversible adsorption of ions, hence no faradic reactions are involved.…”

Hybrid Solid Polymer Electrolytes with Two‐Dimensional Inorganic Nanofillers

“…Boron doping of the gel electrolyte composite improved its thermal stability and the authors found that the specific capacitances of gel electrolytes with and withoutG Oa re almost similar (Figure 14 A), the only significant difference in charges torage values evident when the cell was cycled at slow scan rates.T his may be creditedt o the intimate contact betweent he electrodes by the gel electrolyte,b ut using impedance spectroscopy it was found that GO may be exhibiting pseudocapacitance that can contribute to the increased C s .

Water retention of GO was studied in thermally crosslinked GO/PVAe lectrospun composites by Pan et al, [90] in which alaser-scribedsupercapacitor was createdb yd rop-casting GO onto the GO/PVA electrospun mat followed by laser ablation to create laser-reduced GO electrodes (Figure 14 B).…”

Hierarchically porous carbon derived from an aqueous curable composition for supercapacitors

“…Electric double-layer capacitors, often known together with pseudocapacitors as supercapacitors, have recently attracted significant attention in high power electrochemical technology research owning to their higher power density, higher energy density, excellent pulse charge-discharge characteristics and long cycling stability [1][2][3][4][5][6][7][8]. By investigating the behavior of electric double-layer capacitors, large specific surface area, synergistic effect of micropores/mesopores/macropores, and adequate pore size distribution have been confirmed playing extremely crucial roles for the electrode materials to obtain superior electrochemical performance [1][2][3][4][9][10][11][12][13][14][15][16][17][18].…”
