US 2025/0167281 A1 · METHOD AND DEVICES FOR MANUFACTURING MONO CELLS AND CELL STACKS FOR BATTERIES FORMED FROM THE MONO CELLS

Abstract

A mono-cell manufacturing method for producing mono cells for a battery, wherein the mono cell has a first electrode segment, a second electrode segment and a separator layer between the first electrode segment and the second electrode segment, and at least one separator layer on a facing-away surface of the first and/or second electrode segment. The method includes: providing a first electrode string having a first separator web and first electrode segments attached and fixed thereto at a distance from one another; positioning and direct lamination of second electrode segments and a second separator web on the first electrode string so that the first and second electrode segments are superposed in alignment with one another; and cutting the mono cells from the composite string. Also a device and a controller for same.

Dependent claims

A method for manufacturing mono cells for a battery, each mono cell having a first electrode segment, a second electrode segment, a separator layer between the first electrode segment and the second electrode segment, and at least one separator layer on a facing-away surface of the first electrode segment, or the second electrode segment, or both, the method comprising the steps of:

A) providing a first electrode string having a first separator web and first electrode segments attached and fixed thereto at a distance from one another;
B) positioning and direct lamination of second electrode segments and a second separator web on the first electrode string so that first and second electrode segments are superposed in alignment with one another as a composite string;
and,
C) cutting mono cells from the composite string obtained in step B).

1 more element

A device for manufacturing mono-cells, the device comprising:

an electrode string providing device for providing a first electrode string comprising a first separator web and first electrode segments attached and fixed thereto at a distance from one another,
a positioning and laminating device which is configured to position second electrode segments on the first electrode string in alignment with the first electrode segments and to directly laminate the second electrode segments and a second separator web directly onto the first electrode string to form a composite string, and
