Data about the development of eco-friendly Pullulan/ Polyvinyl Alcohol composites based all-solid-state supercapacitors

Here the raw data related to the development of a solid state-based supercapacitor using Pullulan (Pu)/Polyvinyl Alcohol (PVA) composite as an eco-friendly binder are reported. PVA/KOH/Glycerol (GCy) blends are used as conductive electrolytes towards safe and light weight devices manufacturing. The electrodes are fabricated through simple and low-cost hand-painting (paint brush) on Nickel foam substrates.
