Abstract
The invention relates to a supercapacitor that comprises at least two juxtaposed complexes (1, 2) spaced by a distance d, and at least one common complex (3) located opposite the two juxtaposed complexes (1, 2) and spaced therefrom by at least one spacer (4), the spacer (4) and the complexes (1, 2, 3) being spirally wound together in order to form a coiled element.
Claims23
A supercapacitor with a double electrochemical layer, comprising two juxtaposed complexes (1, 2) spaced apart by a distance d along a direction parallel to a longitudinal axis, and a common complex (3) facing each of the juxtaposed complexes (1, 2) and separated from the latter by at least one separator (4), each of said juxtaposed and common complexes including a current collector and at least one electrode, the separator (4) and said juxtaposed and common complexes (1, 2, 3) being wound together in turns along the longitudinal axis in order to form a wound element, wherein the separator (4) includes at least two portions spaced apart by a distance w of less than the distance d, each of the portions entirely separating said juxtaposed and common complexes (1, 2, 3) facing each other.
A module comprising:
- a casing;
- and
- at least one supercapacitor disposed in said casing, said supercapacitor with a double electrochemical layer, comprising two juxtaposed complexes (1, 2) spaced apart by a distance d along a direction parallel to a longitudinal axis, and a common complex (3) facing each of the juxtaposed complexes (1, 2) and separated from the latter by at least one separator (4), each of said juxtaposed and common complexes including a current collector and at least one electrode, the separator (4) and said juxtaposed and common complexes (1, 2, 3) being wound together in turns along the longitudinal axis in order to form a wound element, wherein the separator (4) includes at least two portions spaced apart by a distance w of less than the distance d, each of the portions entirely separating said juxtaposed and common complexes (1, 2, 3) facing each other.
