#$%^&*AU2012203598A120120712.pdf#####ABSTRACT The present invention relates to the production of electrochemical capacitors with a DEL. The proposed electrodes with DEL are based on non-metal conducting materials, 5 including porous carbon materials, and are capable of providing for high specific energy, capacity and power parameters of electrochemical capacitors. P- type conductivity and high concentration of holes in electrode materials may be provided by thermal, ionic or electrochemical doping by acceptor impurities; irradiating by high-energy fast particles or quantums; or chemical, electrochemical and/or thermal treatment. The present invention 10 allows for an increase in specific energy, capacity and power parameters, as well as a reduction in the cost of various electrochemical capacitors with DEL. The proposed electrodes with DEL can be used as positive and/or negative electrodes of symmetric and asymmetric electrochemical capacitors with aqueous and non-aqueous electrolytes.
