“…They assembled asymmetric supercapacitor electrode device with a MoS 2 -NiO//MoS 2 -Fe 2 O 3 configuration, and the device shows a maximum energy density and good cycling performance. K. Chanda and coworkers [45] prepared 3D hierarchical nanoform based on TiO 2 sphere and MoS 2 flake by low-temperature hydrothermal synthesis protocols. Surface area increased due to the wrapping of MoS 2 flakes over TiO 2 sphere.…”

Supercapacitors evolved as a breakthrough to the existing shortages in energy resources because of its enhanced capacitive performance, long-term stability, and high power density. Transition metal oxides (TMOs), a redox active material in energy storage applications, showing high specific capacitance (100–2000 F/g) than the electrical double-layer capacitor (EDLC) material has been reviewed a lot. Among various TMOs, nickel oxide (NiO), tin oxide (SnO2), manganese dioxide (MnO2), tungsten oxide (WO3), vanadium pentoxide (V2O5) are widely used by researchers due to their high theoretical capacitance, low cost, and long cycle life. The limitations of TMO-based electrode material includes low electrical conductivity, ion mobility, and low energy density. It is thus important to develop proper combination of TMO with other transition metals, TMOs, transition metal dichalcogenides (TMDs), conducting polymers (CPs) and carbon-based materials (graphene oxide (GO), activated carbon (AC) and reduced GO (rGO)). This chapter focuses on ongoing development in six TMO-based electrode material (NiO, ZnO, MnO2, SnO2, WO3, V2O5) fabrication for the enhancement of electrochemical performance, their synthesis method and then review about the recent progress in studying the supercapacitor performance of the material. The limitations of each TMOs listed separately, providing new insights for future energy storage applications.

“…They found that incorporating Mn 3 O 4 improved the capacitance of layer-structured MoS 2 from 47.2 F g À1 to 119.3 F g À1 . Chanda et al 16 showed that a specific capacitance of 152.22 F g À1 at a current density of 0.1 A g À1 is achieved when TiO 2 spheres are added into MoS 2 nanoflakes. Ahmad et al 14 fabricated Co 3 O 4 -decorated MoS 2 nanoflowers by a simple hydrothermal route.…”

“…Preparing composites for active electrode material is the most effective approach to enhance the overall performance of supercapacitors. [22][23][24][25][26] Cellulose is the most prevalent and sustainable biopolymer on the earth and is widely used as a component of supercapacitors. Moreover, the excellent flexibility, low cost, superior hydrophilicity, and, most importantly, sustainable characteristics of cellulose make it the superior choice for ESDs.…”

Microwave‐Induced Rapid Synthesis of MoS₂@Cellulose Composites as an Efficient Electrode Material for Quasi‐Solid‐State Supercapacitor Application

Transition‐metal dichalcogenides (TMDs) are highly desired for energy‐storage devices due to their intrinsic layered structure, huge surface area, and the large number of active sites. However, the TMDs fail to reach their potential due to restacking of 2D layered structures that remains a major technological hurdle. Herein, MoS2 nanosheets and cellulose fiber binary composite (MoS2@Cellulose) prepared by the microwave‐assisted technique are demonstrated as an electrode material for supercapacitor application. The prepared material are tested in symmetric and asymmetric all solid‐state device assemblies. It is found that the quasi‐solid‐state symmetric and quasi‐solid‐state asymmetric supercapacitors exhibited remarkably higher specific capacitance of ≈294 and ≈177 F g−1 at a current density of 1 A g−1, respectively, than their counterpart. Furthermore, the symmetric and asymmetric devices deliver excellent energy densities of ≈40.84 and ≈42.67 Wh kg−1 while maintaining the power density of 400 and 791.81 W kg−1, respectively, and outstanding cyclic stability. The cellulose entanglement causes a reduction in the aggregation and restacking of MoS2, which may improve the electrochemical performance of the supercapacitor. Herein this research, a pathway is provided to create an efficient energy‐storage system using 2D materials with sustainable cellulose.
