Abstract: A method of manufacturing an electrode group unit for lithium ion capacitor that allows reliable welding between a current collecting member and an electrode and that provides a welded portion with a low resistance is provided. A lithium ion capacitor is also provided. An unapplied portion 25 of a positive electrode 9 and an unapplied portion 33 of a negative electrode 11 are disposed to project outside of separators 13, 15 in directions opposite to each other. The resulting assembly is wound into a swirling shape in cross section about an axial core 7 to form an electrode group 5. A lithium metal support member 17 is disposed on the negative electrode 11 such that a layer in which the lithium metal support member 17 is wound is located in a radially middle region of the electrode group 5.

Abstract: A present invention provide a lithium ion storage device capable of reliably doping a negative active material of a negative plate with lithium ions generated through dissolution of a lithium metal plate disposed in an electrode group. A conductive shielding member includes a current collecting metal foil and a negative active material layer formed on at least one surface of the current collecting metal foil. The conductive shielding member is provided between a lithium metal plate and a positive plate such that the lithium metal plate is sandwiched between the negative plate and the negative active material layer formed on the current collecting metal foil of the conductive shielding member.

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.

Abstract: A mass-producible lithium ion capacitor that allows lithium ions to be easily occluded by a negative electrode in advance is provided. A layered member includes: two copper foils each having a portion in which tabs are formed on one side along the longitudinal direction of the copper foils, and a portion in which a large number of through holes are formed and which is disposed adjacent to the portion with the tabs, and lithium metal having a thin plate shape and sandwiched between the copper foils to contact the portions with the through holes of the copper foils. The tabs are joined to a negative current collector ring, and electrically connected to a negative current collecting member. By leaving the layered member to stand for a predetermined period, it is possible to cause lithium ions to be occluded by a negative active material of the lithium ion capacitor.
