CARBONIFER ACTIVE MATTER FILM, ELECTRODE FOR ENERGY STORAGE SYSTEMS, ITS MANUFACTURING PROCEDURE AND ENERGY STORAGE SYSTEM THAT INCLUDES SUCH ELECTRODE.

摘要

Carboniferous active matter film for electrode of energy storage systems of the double layer type, such as supercapacitors, characterized in that it is constituted on the basis of at least one active carbon (AC), which has the following characteristics: a) porosity: b) - microporous volume (diameter 2 nm) determined according to the DFT method between 0.5 cm 3 / g and 0.75 cm 3 / g and, preferably, between 0.5 cm 3 / g and 0, 65 cm 3 / g, and which represents at least 75% and, preferably, at least 78% of the total porosity of said coal, - BET specific surface area between 1,200 and 1,800 m 2 / g, of preferably, between 1,200 and 1,600 m 2 / g, purity: - degree of total ash, determined according to ASTM method D2866-83 less than 1.5% by weight, - the mass percentages of the following impurities, determined by mineralization (attack with HNO3 / H2O2) followed by an analysis by spec Emission geometry (ICP) or, for chlorides, by extraction with water followed by an analysis by ion chromatography, are such that: - [chlorides] = 80 ppm - [chromium] = 20 ppm - [copper] = 50 ppm [iron] = 300 ppm - [manganese] = 20 ppm - [nickel] = 10 ppm - [zinc] = 20 ppm c) granulometry, determined by laser diffraction, such that 3 mim = D50 = 15 m and 10 m = D90 = 60 m and d) pH, determined according to the CEFIC method, between 3.5 and 9, preferably between 4.5 and 8, and, at least, based on a polymer material, with a thickness less than or equal to 1 mm and, preferably, between 30 and 500 m.
