In this work, hierarchical manganese-nickel sulfide nanosheet arrays (Mn-Ni-S NAs) were designed through a cost-effective hydrothermal method, followed by an ion-exchange technique. Among the various electrode samples prepared, Mn-Ni-S NAs with Mn/Ni feeding ratio of 1:2 (denoted (1:2)) found to possess outstanding electrochemical properties, including superb areal capacity 0.687 mAh cm-2 (286.3 g-1 specific capacity) and splendid cycling stability. Furthermore, (1:2) can be coupled iron oxide embedded in reduced graphene oxides (Fe2O3@rGO) assemble all-solid-state asymmetric supercapacitor devices. The resultant device demonstrated superior volumetric energy density 76.6 W h kg-1 prominent current synthesis protocol provides meritorious reference for other kinds transition-metal materials storage applications.

The incorporation of renewable and sustainable energy sources in electric grids has been acknowledged as a potential strategy to solve the ever-growing environmental issues that result from use fossil fuels. In order realize full these systems, advanced electrochemical storage devices must be developed. Recently, researchers have turned their attention toward obtaining high-performance electrode nanomaterials develop next-generation systems. Metal–organic frameworks (MOFs), well-known for relatively straightforward fabrication methods, high nanoscale porosities, robust nanostructures, intrinsic crystallinities, emerged class potentially capable meeting stringent demands Specifically, bridged MOFs other MOF derivatives recently established primary MOF-based studies on such batteries capacitors, demonstrated address poor conductivities arise separated nanoparticles early reports MOF-only As such, we focused this review nanomaterials, particular, discuss advantages disadvantages systems with range support materials, including carbon nanotubes, fibers, graphene, metals, metal oxides, conductive polymers. Finally, highlight remaining challenges possible opportunities research field facilitate future studies.
