Zusammenfassung:The invention relates to a supercapacitor with electrolyte as gel, meant to be used for storing electric energy. The supercapacitor comprises a positive electrode with conductive polymer deposited thereon, a negative electrode, without conductive polymer, a separating membrane and an electrolyte as gel prepared by using 2 g of polyvinyl alcohol dissolved in 50 mL of ionized water, at a temperature of 70°C, while stirring for 8 h, to which phosphoric acid is added until a concentration of 10...50% is obtained, then potassium iodide 0.1 M and quinone 0.1% are added, the thus obtained solution being left at the ambient temperature for 72 h, for stabilization purposes. Invenţia se referă la un supercapacitor cu electrolit gel, destinat stocării energiei electrice. Supercapacitorul este alcătuit dintr-un electrod pozitiv, cu polimer conductiv depus, dintr-un electrod negativ, fără polimer conductiv, o membrană separatoare şi un electrolit gel obţinut utilizând 2 g de alcool polivinilic, dizolvat în 50 mL de apă ionizată, la temperatura de 70°C, cu agitare timp de 8 h, la care se adaugă acid fosforic, până se obţine o concentraţie de 10...50%, iodură de potasiu 0,1 M şi chinonă 0,1%, soluţia astfel obţinută fiind lăsată la temperatura ambiantă timp de 72 h, pentru stabilizare.
