Title: Battery jar for storage battery and storage battery
Inventor: NOMURA TETSUO
IPC: H01M2/02
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To suppress the increase in thickness of an electrode plate group to improve the life of a battery by forming a pair of both sidewalls opposed to both end surfaces of an electrode plate group housed in the inner part as inward curved walls, and providing a rib for supporting it from the outside on the outer surface of each curved wall. SOLUTION: When an electrode plate group is increased in the laminating direction by the rise of internal gas pressure, an outward expanding pressing force is applied to the opposed sidewalls thereof. However, since both the sidewalls are formed into inward curved walls a1, a3, they strongly resist against the expanding pressure of the electrode plate group, so that the adhesion of a positive electrode plate, a separator and a negative electrode plate constituting the electrode plate group can be ensured to keep satisfactory battery performance over a long period.  Further, since both sides of arch ribs 2 integrally provided on the outer surfaces of the inward curved walls a1, a3 are continuously connected to the upper and lower edges b1, b2 of the four circumferential edges of the inward curved walls a1, a3 immovable to the internal pressure to support the inward curved walls a1, a3, their outward expansion deformation can be firmly suppressed.
