The stable and efficient supercapacitor investigation synthesized tungsten-based oxides using many approaches. The impact of the tungsten precursor on the product was significant in this research, and the most important consequences are highlighted. Supercapacitors and other energy storage devices have been using tungstate metal oxide because of its high electrical conductivity as well as low manufacturing costs. This article is mostly about how tungsten oxide-based electrodes for supercapacitors (SCs) and batteries have changed in recent years. Electrodes for energy storage devices made of nanostructured materials can benefit from a variety of features, including high surface-to-volume ratios, excellent charge transport capabilities, as well as excellent physical-chemical properties. Nanostructures and nanocomposites for supercapacitors and storage applications will be summarized in this paper.
