Title:
A manufacturing method of an accumulation-of-electricity device and an accumulation-of-electricity device
Document Type and Number:
Japanese Patent JP5958340
Kind Code:
B2
Abstract:
An electrochemical capacitor that is resistant to vibration is provided. A positive current collecting member 39 is welded to an unapplied portion 25 of a positive electrode 9 included in a wound electrode group 5. An outer peripheral portion 40 of the positive current collecting member 39 is shaped and sized to extend to a position beyond a top portion 3c of an annular projected portion 3a. An insulating ring member 63 is disposed in a compressed state between the positive current collecting member 39 and the annular projected portion 3a and also between the positive current collecting member 39 and the annular projected portion 3a and an annular wall portion 3d of a peripheral wall portion that is continuous with the annular projected portion. This configuration makes it possible to reliably fix an electrode group unit in a container 3 while preventing a short circuit.
