Abstract
The present invention relates to the field of the synthesis of porous carbon materials and their use in the manufacture of electrodes with a double electric layer (DEL) for electrochemical capacitors having an aqueous and organic electrolyte having high specific energy parameters. The synthesis technology makes it possible to manufacture porous carbon powders made of carbohydrate substances with a low content of ash and metals in the powders with high specific capacitances and low specific electrical resistances.
