FILM OF CARBONACEOUS ACTIVE MATERIAL, ELECTRODE FOR ENERGY STORAGE SYSTEMS, PRODUCTION METHOD THEREOF AND ENERGY STORAGE SYSTEM COMPRISING SAID ELECTRODE

摘要

The invention relates to an electrode for energy storage systems, the production method thereof, and an energy storage system comprising said electrode. More specifically, the invention relates to films of carbonaceous active material based on activated carbon with a determined porosity, purity and particle size distribution and a polymer binder, whereby the electrodes comprise one such coating film on a current collector and the supercapacitors comprise at least one of these electrodes. The invention also relates to the method of preparing the aforementioned films, electrodes and supercapacitors.
