電池の変形防止に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to prevention of deformation of a sealed lead-acid battery having a container having at least one surface made of a flexible sheet material such as plastic.
従来の技術とその問題点
密閉式鉛蓄電池の電池内の圧力は放置中に酸素ガスと負
極板の反応により低下する。Prior art and its problems The pressure inside a sealed lead-acid battery decreases during storage due to the reaction between oxygen gas and the negative electrode plate.
また、蓄電池内部には正極板と負極板を隔離し、電解液
を保持するために、一般にガラス繊維不繊布等より成る
セパレータを備えているが、このセパレータは容易に圧
縮力による変形を生じる。Furthermore, in order to isolate the positive electrode plate and the negative electrode plate and to hold the electrolyte, a separator generally made of glass fiber nonwoven fabric or the like is provided inside the storage battery, but this separator is easily deformed by compressive force.

易く、長期間の放置では電解液がセパレータより遊離し
、その電解液が排気孔（図示せず）を通して外部へ漏出
する可能性があった。For this reason, as shown in Fig. 4, in a sealed lead-acid battery in which at least one surface of the battery case is made of a flexible sheet 3, as the pressure inside the battery decreases, the surface dents and retains the electrolyte. Compressive deformation of the separator 6 is likely to occur, and if left for a long period of time, the electrolyte may be released from the separator and leak to the outside through an exhaust hole (not shown).

変形を防ぐことは困難である。In addition, all the electrolyte in the battery is separated from the separator 6 and the electrode plate 4.
In a cage-type sealed lead-acid battery impregnated with 5, the contact between the positive and negative electrode plates and the electrolyte, which is essential for the battery reaction, is actually achieved through close contact between the electrode plates and the separator, which increases rigidity. If a separator with a glass fiber I! Alternatively, separators made of synthetic resin fibers are used, and it is difficult to prevent the above deformation.

電池の漏液を防止するものである。Means for Solving the Problems The present invention provides a sealed lead-acid battery in which at least one side of the battery case is made of a flexible sheet material, in which a protrusion is provided on the inner circumferential wall of the battery case in order to prevent deformation due to a decrease in pressure inside the battery. The battery case (sheet portion) can be deformed by placing an electrode plate on the end face of the protrusion and arranging the other side of the electrode plate in contact with the sheet material that constitutes the outer wall of the battery case. It also suppresses deformation of the separator as much as possible to prevent leakage of sealed lead-acid batteries.
