ABSTRACT:
The invention relates to elecrical engineering and can be used for producing electrochemical double-layer capacitors having high specific energy and power characteristics and which can store and give off energy at high speed. The essence of said invention lies in the fact that the active mass of a negative polarised electrode (2) is an organic electroconducting polymer or composite which is based on a carbon or polymer material. A separator (3) is provide with pores which enables additional oxygen molecules to penetrate. The negative polarized electrode (2) is made of a polyaniline composite and an activated carbon material or of an activated carbon material composite and polypyrrole. Aqueous solutions of non-organic acids or mixture or salts thereof or thixotropic mixtures of acids and salts or solid proton conductive compositions are used as electrolytes.
