Title:
TAPE ADHESION METHOD OF ELECTRODE ASSEMBLY
Document Type and Number:
Japanese Patent JP2019046624
Kind Code:
A
Abstract:
To provide a tape adhesion method of an electrode assembly, capable of adhering an end part of a tape to the same position to a plurality of the electrode assemblies.SOLUTION: A tape 40 is adhered to an electrode assembly 20 in which a negative electrode 21 and a positive electrode 23 are laminated from first and second end surfaces 31 and 32 of a lamination direction to a tab side end surface 33a connecting both end surfaces. The tab side end surface 33a is constructed so that an edge part of squeeze-out part 21a squeezing to the side outer than the edge part of the positive electrode 23 in the negative electrode 21 is laminated. The electrode assembly 20 includes: a first area A1 to which an opposite part in which the negative electrode 21 and the positive electrode 23 are opposite to the first and second end surfaces 31 and 32 is projected; and a tab edge part A1a in the edge part near the tab side end surface 33a from the edge part of the first area A1. First and second positions 41 and 42 of the tape 40 are constantly positioned at first and second positions P1 and P2 separated from the tab side edge part A1a by predetermined distances X and Y in the first and second end surfaces 31 and 32, and press them.SELECTED DRAWING: Figure 5
