CURRENT COLLECTOR, ENERGY STORAGE ELEMENT, AND METHOD OF MANUFACTURING CURRENT COLLECTOR
First Claim
1. A current collector comprising:
- a terminal connecting portion;
a first electrode connecting portion including a first surface extending forward and downward from a right frontal portion of the terminal connecting portion;
a second electrode connecting portion including a second surface extending forward and downward from a left frontal portion of the terminal connecting portion and opposing the first surface;
a first twisted portion having an end portion connected to the right frontal portion and the other end portion connected to an upper end portion of the first electrode connecting portion; and
a second twisted portion having an end portion connected to the left frontal portion and the other end portion connected to an upper end portion of the second electrode connecting portion,wherein a clearance between surfaces defined as a distance between the first surface and the second surface in a left-right direction is larger than a distance between the center of the right frontal portion in the left-right direction and the center of the left frontal portion in the left-right direction.

Abstract
A positive electrode current collector includes a terminal connecting portion, a first electrode connecting portion including a first surface extending forward and downward from a right frontal portion, a second electrode connecting portion including a second surface extending forward and downward from a left frontal portion and opposing the first surface, a first twisted portion having an end portion connected to the right frontal portion and the other end portion connected to an upper end portion, and a second twisted portion having an end portion connected to the left frontal portion and the other end portion connected to an upper end portion. A distance between the first surface and the second surface is larger than a distance between the center of the right frontal portion and the center of the left frontal portion.

9. A method of manufacturing a current collector,
the current collector including: -
a terminal connecting portion; a first electrode connecting portion including a first surface extending forward from a right frontal portion of the terminal connecting portion; and a second electrode connecting portion including a second surface extending forward from a left frontal portion of the terminal connecting portion, the method comprising; forming a first twisted portion having an end portion connected to the right frontal portion and the other end portion connected to an upper end portion of the first electrode connecting portion, by rotating and twisting downward the first electrode connecting portion with respect to the terminal connecting portion such that the first surface extends forward and downward from the right frontal portion; and forming a second twisted portion having an end portion connected to the left frontal portion and the other end portion connected to an upper end portion of the second electrode connecting portion, by rotating and twisting downward the second electrode connecting portion with respect to the terminal connecting portion such that the second surface extends forward and downward from the left frontal portion so as to oppose the first surface, wherein the forming of the first twisted portion or the forming of the second twisted portion includes twisting the first electrode connecting portion or twisting the second electrode connecting portion such that a clearance between surfaces a distance between the first surface and the second surface in the left-right direction becomes larger than a distance between the center of the right frontal portion in the left-right direction and the center of the left frontal portion in the left-right direction. - View Dependent Claims (10, 11, 12)
