The growth of nickel-manganese and cobalt-manganese layered double hydroxides on reduced graphene oxide for supercapacitor

Anchored Fe3O4 Nanoparticles on rGO Nanosheets as High‐Power Negative Electrodes for Aqueous Batteries

“…Accordingly, it can be seen that the I D /I G ratio increased in the case of rGO (1.06) in comparison with that of GO (0.98), This can be attributed to the increased number of smaller poly-aromatic domains and a highly defective carbon lattice. [28] Similar peaks can be also seen in the nanocomposite sample, demonstrating the presence of iron oxide particles hybridized with the graphitic matrix which is in agreement with previously observed XRD results. This can be due to reduced sp 2 domains in the course of dehydration reactions and anchoring metal oxide nanoparticles on the basal plane of reduced graphene oxide.…”

Three-dimensional nickel vanadium layered double hydroxide nanostructures grown on carbon cloth for high-performance flexible supercapacitor applications

“…The capacitance decay may be due to a phase change, structural collapse or reduction of the active surface area during chargingdischarging. 46 To further explore the potential of NVL@CC in exible and lightweight wearable electronics, hybrid supercapacitor (HSC) devices were fabricated using PVA/LiCl as a gel polymer electrolyte.

Recent Progress in Two‐Dimensional Layered Double Hydroxides and Their Derivatives for Supercapacitors

“…In the growth process, metal ions polymerize with the templatea nd bond togethert of ormawell-defined nanocomposite. These materials can normally be obtained by coprecipitation, electrodeposition, and hydrothermal methods, such as NiAl LDH/graphene nanosheets (GNSs), [103,106] CoAl LDH/G, [107] NiÀMn LDH/rGO, [108] CoMn LDHs/rGO, [109] NiCo LDH/rGO, [59] CoFe LDH/multilayer G, [110] NiFe LDH/rGO, [111] NiCo 2 O 4 /G, [112] NiCo 2 S 4 /H-3DRG, [113] and NiCo 2.1 Se 3.3 /3DG. [114] The exfoliation-stacking strategy is favorable due to the productiono fu ltrathin nanosheets.…”
