摘要: Abstract A biodegradable low-cost energy storage material has been obtained by using a self-assembly nanocomposite gelatin and graphene flakes. The blends with various ratio of have prepared characterized Raman spectroscopy, cyclevoltammetry measurements, chronopotentiometry measurements impedance spectroscopy. ability the biopolymer to bind water–glycerol molecules flakes leads an improvement dielectric properties value surface capacitance about 3 orders higher (10 mF cm −2 ) than that measured for device based on activated carbon. An electrical oxidation at anode contact observed applying bias voltage. modified active exhibits enhancement cycle stability further increase (100 mF cm respective specific up 380 F g −1 .
