EDDY-SHAPED ELECTRODE AND METHOD OF MANUFACTURING EDDY-SHAPED ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide an eddy-shaped electrode and a manufacturing method for the same that can shorten a separator sheet while maintaining the performance of an electrode.SOLUTION: In an eddy-shaped electrode 10, a first region 71 is a region where the short side 43 of a first separator sheet 40 and the short side 53 of a second separator sheet 50 are aligned with each other, a second region 72 is a region where a negative electrode sheet 30, a first separator sheet 40, a positive electrode sheet 20, and a second separator sheet 50 are aligned with one another in the radial direction of the eddy, and also which is formed so as to extend, in the peripheral direction of the eddy, from a position where the short side 34 of the negative electrode sheet 30 and the short side 24 of the positive electrode sheet 20 are aligned with each in the same phase, to the short side 25 of the positive electrode sheet 20. The third region 73 is a region in which the negative electrode sheet 30, the first separator sheet 40, and the second separator sheet 50 are arranged in the radial direction of the vortex, and in the circumferential direction of the vortex, from the short side 25 of the positive electrode sheet 20 to the short side 35 of the negative electrode sheet 30.SELECTED DRAWING: Figure 2
