Abstract

This invention is provided with a battery which includes: cells 1 provided with a positive electrode member, a negative electrode member, and an electrolyte; a pair of pressure application members (2a, 2b) sandwiching the cells and holding the cells while applying pressure thereto from both sides at a predetermined pressing force; and a lock mechanism 3 for restricting operation of the pressure application members in the event of a force greater than the predetermined pressing force applied to the cells by the pair of pressure application members acting in the direction opposite that from thepressing members towards the cells, so that the cells are held between the pair of pressure application members while being subjected to the predetermined pressing force. The present invention is alsoconfigured so that the lock mechanism does not obstruct the operation of the pressure application members in the direction in which the cells are pressed.

Description

technical field [0001] The present invention relates to a battery, and more specifically, to a battery having a structure in which a battery cell including a positive electrode member, a negative electrode member, and an electrolyte is held between a pair of pressurizing members. Background technique [0002] In recent years, batteries have been widely used as power sources for automobiles. One of the batteries used for the above-mentioned application is the battery (battery pack) disclosed in Patent Document 1. [0003] That is, the battery (battery pack) includes: a battery stack formed by stacking a plurality of flat batteries; a set of pressure plates sandwiching the battery stack; and a set of pressure plates sandwiching a set of pressure plates. A pressing force applying member; and a connecting member that connects a group of pressing force applying members and is capable of acting in a direction in which each pressing force applying member approaches each other, whe...
