Chernysh O. The technology of obtaining composite materials based on water-soluble binders for electrochemical capacitors

Dissertation is devoted to the development of the technology of composite materials for electrochemical capacitors based on water-soluble polymeric binders. Aqueous emulsion of polyvinylidene Solef XPH - 884 was used as the main component. Introduction of other water-soluble components and optimization of composite electrode system made it possible to create a capacitor prototype with the specific power of 73 kW / kg and the specific energy of 33 W·h / kg, which is significantly higher to conventional EC for energy density. Based on the results of investigations there were analyzed the influence of polymeric binder, the nature of metal current collector surface, the adhesion, mechanical and electrochemical properties. The technology of electrochemical capacitor electrodes with usage of new environmentally friendly materials was developed. Keywords: electrochemical capacitor, increased energy, a water-soluble binder.
