Abstract Two dimensional nanomaterials (2D) are considered to be one of the most important electrode materials in energy applications because their unique structure with enhanced physical and chemical properties. To fabricate a high capacitance material is tedious process due low density self-discharge rate. In recent years, various transition metal sulphides composites have been widely used electrochemical devices electrocatalysis. Among them two tin sulphide nanoflakes (SnS 2 Nfs) attracted increasing attention owing large surface area interlayer crystal structure. Here, we investigated 2D SnS Nfs promising for storage which was prepared through simple hydrothermal effect structural, morphological properties were studied. As-synthesized found poses hexagonal phase an average crystallite size 28 nm estimated from X-ray diffraction (XRD). FE-SEM image attributes formation nanoflakes. The XPS spectrum revealed Sn 3d S 2p proposed respective peaks observed Nfs. as synthesized exhibits specific 380 F/g at current 1 A/g excellent cyclic stability. retains 89 % initial after 3,000 cycle 10 A/g.

Supercapacitors have attracted increasing research interest in the search for high-power and high-energy-density energy storage systems, because they combine exceptional power density of double-layer electrodes with high faradaic-type into a single device. Biomass has been used as renewable precursor to prepare carbonaceous supercapacitor application, its diverse compositions morphologies, excellent intrinsic structures, renewability. Moreover, biomass activated carbons combined pseudocapacitive/2D materials become more popular high-performance supercapacitors recent years. Therefore, we provide an overview developments carbon-based composites containing metal oxides, hydroxides, sulfides, MXenes, metal–organic frameworks (MOFs), polymers some physical properties their applications supercapacitors. These offer lot commercial application potential, remarkable electrochemical stability, cyclic electrical conductivity, effective charge transport kinetics at electrode/electrolyte junction. In relation utilization electrodes, completed this Review future trends opportunities development composite carbon conductive template.

As the demand for innovative electronic devices continues to grow, flexible products which offer a solution capable of adapting various shapes and deformations, are increasingly gaining prominence. This study innovatively uses electrospun polyvinylidene fluoride (PVDF) nanofibers as substrates employs reactive inkjet printing (RIP) technology deposit instantaneously reduce graphene oxide (GO), fabricating ultralight all-solid-state supercapacitors. To verify that PVDF can facilitate uniform deposition GO ink during prevent dispersion into internal structure, thereby achieving good capacitive performance with fewest layers printing, this analyzes compares differences among 1rGO/PVDF, 3rGO/PVDF, 5rGO/PVDF samples. The results have been confirmed was effectively in-situ reduced by l-ascorbic acid (AA) rGO RIP system, specific capacitance 1rGO/PVDF electrode founded 83.29 F/g at current density 2 A/g from GCD analysis corresponding energy 7.5 Wh kg−1 power 1.04 kW kg−1. supercapacitor exhibits excellent electrochemical stability, maintaining 93 % efficiency after 4000 charge-discharge cycles A/g.
