Title:
FLAT-WOUND ELECTRICITY STORAGE DEVICE CELL AND FLAT-WOUND ELECTRICITY STORAGE DEVICE MODULE
Document Type and Number:
WIPO Patent Application WO/2011/027683
Kind Code:
A1
Abstract:
Disclosed is a flat-wound electricity storage device cell and a flat-wound electricity storage device module wherein the width of the module and cell is compact with respect to the direction of the winding axis. In a cathode collector foil, a blank space where a cathode collector foil is not formed is left at a location that does not overlap with an anode collector foil, and in an anode collector foil, a blank space where the anode collector foil is not formed is left at a location that does not overlap with the cathode collector foil. The cathode terminal includes a cathode collector foil connector that connects to the blank space of the cathode collector foil; a cathode terminal external lead; and an in-cell cathode terminal radiator that is located between the cathode collector foil connector and the cathode terminal external lead and that covers approximately half of one of the wide sides of a flat-wound electrode. The anode terminal includes an anode collector foil connector that connects to the blank space of the anode collector foil; an anode terminal external lead; and an in-cell anode terminal radiator that is located between the anode collector foil connector and the anode terminal external lead and that approximately covers the remaining portion of one of the wide sides of the flat-wound electrode.
