SYSTEMS AND METHODS FOR MANUFACTURING BATTERY CELLS

Abstract:

Methods of laminating a multilayer substrate may utilize particular lamination systems to perform the methods. The methods may include providing the multilayer substrate, which may include a base, in a feed direction through a laminating system. The base may support segments of a material, each segment characterized by a height past the base in a direction normal to the feed direction. Each segment may define a leading edge at an intersection of a second surface and a third surface, and the segments may be separated from one another along the base by a spacing length. The methods may include contacting a first segment with a set of pinch rollers. The contacting may limit interaction with the third surface at the leading edge of the first segment. The methods may include compressing the first segment against the base in a direction normal to the feed direction.
