Title:
STORAGE BATTERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/122181
Kind Code:
A1
Abstract:
Disclosed is a storage battery device in which there is no increase in electrical resistance between electrode terminals and in addition short-circuiting of a positive-pole electrode terminal sheet and a negative-pole electrode terminal sheet does not occur, even during prolonged use. The storage battery device comprises: an outer container which is constituted by mutually overlaid outer films that are joined in a mutually airtight manner by means of joining sections formed along the outer peripheral sections of each of the outer films; an electrode unit which is accommodated in the outer container and is constituted by arranging a positive-pole electrode sheet and negative-pole electrode sheet, which are constituted by electrode layers respectively formed on current collectors, so that the positive-pole electrode sheet and the negative-pole electrode sheet are overlaid with a separator therebetween; a positive-pole electrode terminal and a negative-pole electrode terminal which are provided so as to project from the inside of the outer container to the outside by way of the joining sections; and an electrolytic solution which is filled inside the outer container. The positive-pole electrode terminal has: a terminal base which is made of aluminium; and a nickel-plating coating which is formed on the surface of the outer end portion of the terminal base, with the outer end portion being positioned outside of the outer container. The inner edge of the nickel-plating coating is positioned inside the joining sections.
