Abstract
Official abstract text for this publication.
An electricity storage device including at least one electrode having one metal tab lead and plural electrode plates. The electrode plate includes a metal foil, an undercoat layer formed on one surface or both surfaces of the metal foil, and an active material layer formed on a surface of the undercoat layer. The undercoat layer includes a carbon material and the undercoat layer has a coating weight per unit area of one surface of 0.01 to 3 g/m 2 . A sum total thickness of the metal foils in the electrode plates is 0.2 to 2 mm. The electrode plates are welded to each other in a portion where the undercoat layer is formed and no active material layer is formed. Further, at least one of the electrode plates is welded to the metal tab lead in a portion where the undercoat layer is formed and no active material layer is formed.
First claim
