Document Type and Number:
WIPO Patent Application WO/2014/092031
Kind Code:
A1
Abstract:
The present invention minimizes increases in temperature within a battery, prevents contact failure, prevents short circuits between electrodes, and provides a battery that is easy to assemble. In the present invention, an electrode block (21) is provided with: an electrode group (23) in which a positive electrode (23a), a negative electrode (23b), and separators (23ca, 23cb) that are arranged between the positive electrode and the negative electrode are layered; a lid member (24) that is provided to both ends of the electrode group in the layering direction thereof; and a first holding member (22a) that is attached to the outer surface of the electrode group and the lid member. The first holding member is electrically connected to a first electrode that is either the positive electrode or the negative electrode, and is not electrically connected to a second electrode that is the other electrode of the positive electrode and the negative electrode. A hole that is provided to the electrode group and the lid member forms a through hole (25), and a second holding member (22b) is attached to the through hole in order to produce the electrode block. The electrode block is accommodated in a layered state in an external body and a collector is inserted in the through hole to produce a layered battery.
