Abstract
Disclosed is a super capacitor and method of manufacture thereof. This invention relates to a solid state super capacitor comprising a solid state polymer electrolyte and a modified carbonaceous electrode. Said modified carbonaceous electrode comprises a conductive carbonaceous material covered with active ingredients. Said modified carbonaceous electrode and said solid state polymer electrolyte are layered on top of each other to form a sandwich-like structure. Said super capacitor performs much better than known super capacitor comprising liquid or gel-form electrolytes. Said super capacitor has higher conductivity, therefore can be manufactured without a current collector. Since said super capacitor contains solid state polymer electrolyte, the method of manufacturing said super capacitor is more environmentally friendly and has a higher safety level.
