The work is devoted to improving methods for obtaining nanoporous carbon material from natural raw materials with their predetermined physicochemical properties, developed surface area and controlled pore structure. The testing of these materials as the base component for electrodes of electrochemical charge accumulation systems was realised. It is shown, that thermochemical activation of hydrothermal carbonized feedstock by potassium hydroxide provides a nanoporous carbon material with an average size of pores 1,7 – 2,2 nm, total volume of 0,8 cm3/g and high surface area of 1600 m2/g, where mesopores are 15% of the total pores. Optimized method of obtaining mesoporous carbon material shows that the surface area is 1500 m2/g, total pore volume is 1,3 cm3/g and mesopore size is 5 – 50 nm, which make up 75% of the total pores.
