Abstract
The invention relates to a supercapacitor with a double electrochemical layer that comprises at least two complexes (2, 3) and at least one spacer (4) between the two complexes (2, 3), the complexes (2, 3) and the spacer (4) being spirally wound together in order to form a coiled member (10), characterized in that it 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) in order to form at least one subsequent coiled member (20), the consecutive coiled members (10, 20) being separated by an electronic insulation space.
Claims36
A supercapacitor with a double electrochemical layer, comprising at least two complexes and at least one separator between the at least two complexes, each complex including a current collector and at least one electrode, wherein the supercapacitor further comprises at least one other complex and at least one other separator, the complexes and the separators being wound together in turns along a longitudinal axis z of the supercapacitor:
- the at least one other complex being successive to one of the at least two complexes in order to form two successive complexes spaced across a distance q circumferential to the longitudinal axis z of the supercapacitor, and
- the at least one other separator being positioned on a face of the complex facing the successive complexes so that said complex extends between the separator and the at least one other separator,
- so as to form at least two successive wound elements, these successive wound elements being separated by an electrically insulating space.
