FIELD: electricity.
SUBSTANCE: present invention relates to a supercapacitor with a double electrochemical layer having at least two complexes (2, 3) and at least one spacer (4) in between, the complexes (2, 3) and the spacer (4) being spirally wound together to form a coiled member (10). According to the invention, the supercapacitor further comprises at least another complex (1) and at least another spacer (4), the other complex (1) and the other spacer (4) being spirally wound together around the coiled member (10) to form at least one subsequent coiled member (20), the consecutive coiled members (10, 20) being separated by an electrically insulating space.
EFFECT: low resistance between two series-connected links of the supercapacitor, high volume and mass density of energy.
