It is shown that polyfluorocarbon prepared by hydrogenation of hard coke improves substantially the electrical characteristics of the cathode. Using the optimal conductive additive based on a mixture of expanded graphite and graphitized carbon black increases the specific capacity of the cathode in ten times and reach a record capacity of 800 mA?h/g for polyfluorocarbon. A prototype of powerful Li - (CFx)n element has developed with discharge current in 8-10 times higher than the "standard" current for commercial elements. The methods of modification of activated carbon (AC) have developed and diapason of potential has defined, were electrodes must be charged - discharged. This enabled the development of asymmetrical supercapacitors (ASC) to obtain a stable and high performance and electrodes on the basis of the modified AC (600 F / g), which is three times greater than their unmodified counterparts. A prototype of stable ASC has developed, where conducting polymers (CPs) used as positive electrodes and modified AC used as negative electrodes. The energy density of laboratory prototype of ASC is 11-31 W?h / kg depending on the type of CP and electrolyte. Key words: lithium batteries, electrochemical capacitor, porous carbon material, activated carbon, polyfluorocarbon. Product Description popup.authors Барсуков В.З. Каташинський А.С. Лихницький К.В.
