FIELD: electrical engineering.
SUBSTANCE: invention can be used in electrical engineering and power engineering when making electrodes of lithium batteries and super capacitors for energy accumulation systems. Dried gel containing at least one hydrophilic polymer type polyhydroxybenzol/formaldehyde. Dried gel is subjected to pyrolysis. Then, impregnated with strong sulphur-containing acid and heat treated in stream of nitrogen at 300-500 °C. Sulphur content on surface of obtained solid porous carbon material is 0.01-0.5 at%. At least 10 % of pores have diameter of 2-50 nm.
EFFECT: material has high mechanical strength, density 0,5-1,3 g/cm3; pores volume 0,4-1 cm3/g, specific surface area greater than or equal to 500 m2/g.
