“…Electrochemical performance of the rGO/NPC-10 electrode self-assembled supercapacitor tested in a two-electrode system in aqueous 1 M H 2 SO 4 , (a) CV curves at various scan rates; (b) GCD curves of different current densities; (c) cycling stability of the rGO/NPC-10-based supercapacitor measured at 5 A/g; (d) power density and energy density of the rGO/NPC-10-based supercapacitor compared with the previously reported electrode materials. − …”

A molybdenum sulfo-oxide/cobalt oxysulfide Z-scheme heterojunction catalyst for efficient photocatalytic hydrogen production and pollutant reduction

“…When the scan rate is 50 mV s À1 , the specic capacitances of Mo(S,O), Co(O,S), MoCoOS-1, MoCoOS-2, MoCoOS-3 and MoCoOS-4 are 0.366, 0.204, 12.0, 13.3, 10.3 and 9.18 F g À1 , respectively. 86 It can be seen from the gure that with the increase of scan rate, the capacitance slightly increases due to the fact that the number of ions contained in the electrolyte transmitted to the electrode increases. As shown in Fig.…”

Recent advances in solid‐state supercapacitors: From emerging materials to advanced applications

“…428 By employing compact and lightweight onedimensional (1D) yarn or fiber electrodes, fiber-based SSCs possess significant advantages over the common planar SSCs as follows: (i) high design versatility that allows them to be formed into various shapes, (ii) high mechanical flexibility enabling conformable structures such as smart textiles, and (iii) easy compatibility and integration with energy harvesting devices to form integrated multifunctional systems. 428,429 Generally speaking, fiber-based electrodes compose of yarn-like carbon-based materials (eg, carbon fiber, 353,[430][431][432][433][434] graphene fiber, [435][436][437][438] AC fiber 353 ), metal wires, polymer nanofibers (eg, polyester fiber, 439 urethane fiber 363 ) and cellulose fibers 440,441 are fabricated by coating active materials via dip coating, 350,353,363 electrodeposition, 442,443 chemical deposition 444 or hydrothermal reaction methods. 445 The common fabrication strategy of fiber-based SSCs is to employ conducting fiber electrodes as current collectors (eg, carbon fiber, graphene fiber, etc.)…”
