FIELD: chemistry.
SUBSTANCE: invention relates to chemistry. Carbon material which is suitable for making electrodes for electrolytic capacitors is obtained via single-step carbonisation of biopolymers with high content of heteroatoms, where there is neither the need to add an activating agent during carbonisation nor subsequent gas-phase activation. Certain biopolymers, which are available through extraction from seaweed, are suitable precursors, or seaweed containing such biopolymers are carbonised directly.
EFFECT: invention simplifies the process of producing the material.
