FIELD: electricity.
SUBSTANCE: electrodes with a double electric layer (DEL) are based on non-metal conducting materials, including porous carbon materials. Conductivity of P-type and high concentration of holes in materials of the electrode may be provided by thermal, ion or electrolytic alloying with acceptor admixtures; by radiation with high-energy quick particles or quanta; or chemical, electrolytic and/or thermal treatment. This invention makes it possible to increase specific energy, capacitance and power parameters, and also to reduce cost of various electrochemical capacitors with DEL. The proposed electrodes with DEL may be used as positive and/or negative electrodes of symmetrical and asymmetrical electrolytic capacitors with aqueous and non-aqueous electrolytes.
EFFECT: high specific energy, capacitance and power parameters of electrolytic capacitors.
