The sol-gel technique tends to form homogeneously dispersed RuO2 nanoparticles with the average size of similar to 2.3 nm on the positive surface curvatures of multilayer fullerene (CNOs), which helps the high diffusivity of ions in both the aqueous and solid state gel electrolytes. The flexible substrate worked excellently as an electrical conductor as well as a stable mechanical support. This solid state flexible energy storage device showed a maximum energy density of 10.62 Whkg(-1) and a maximum power density of 4.456 kWkg(-1) for the hydrous RuO2/CNOs nanocomposite with 94.47% cycling stability even after 4000 cycles.</p>10aCarbon nano-onions10aElectrochemical capacitor10aFlexible conducting substrate10aFlexible energy storage device10aHydrous ruthenium oxide nanoparticles1 aMuniraj, Vedi, Kuyil Azha1 aKamaja, Chaitanya, Krishna1 aShelke, Manjusha, V.  uhttps://library.ncl.res.in/content/ruo2-center-dot-nh2o-nanoparticles-anchored-carbon-nano-onions-efficient-electrode-solid
