Embodiment Construction

[0031] figure 1 A cross-sectional view of a separator leaf 1 is shown with a contact region A for an electrode plate (not shown) and an edge region R on a side edge. The main and auxiliary ribs 2a, 2b are arranged in the contact area A in the normal way.

[0032] The edge region R has a width B R , and the edge region R has a central base material thickness D R , which is greater than the basic material thickness of the diaphragm leaf 1 in the contact area A (ignoring the ribs).

[0033] figure 2 show figure 1 An enlarged detail of the region R of the left edge shown in the sketch of . It can be seen that the basic material thickness D in the boundary area between the edge area R and the contact area A R2 (ignoring the main rib 2a) greater than the basic material thickness D of the contact area A . It can also be seen that the edge region R tapers outwards in a wedge shape, the basic material thickness D of the adjacent edge region R of the partition leaf 1 R1 Increa...

Abstract

A lead-acid rechargeable battery having at least one set of electrodes comprising alternately arranged positive and negative plate-shaped electrodes, between which separators are arranged for the purpose of separating the electrodes of opposing plurality, has separators formed in each case from two separator sheets (1) by joining edge regions (R), which lie one on top of the other, of the separator sheets (1) to form a pocket which is open on one side for the purpose of inserting an electrode plate. The basic material thickness (DR) of the separator sheets (1) at the edge regions (R) increases from the outer edge of an edge region (R) in a direct direction with respect to the bearing region (A) of the separator sheet (1) for an electrode plate. The basic material thickness (DR2) in the edge region (R) adjoining the bearing region (A) is greater than the basic material strength (DN) of the bearing region (A).

Description

technical field [0001] The present invention relates to a lead-acid rechargeable battery having at least one electrode group consisting of alternately arranged positive and negative electrodes having a plate-like shape with spacers for separating opposite polarities arranged between them. The separator of the electrode, each separator is constituted by two separator leaves, forming a pocket (pocket) by joining the overlapping edge regions of said separator leaves, said pocket is open on one side, so that Insert the paddle. [0002] The invention also relates to a separator for separating electrode plates of opposite polarity in such a lead-acid rechargeable battery, having two separator leaves on edge regions superimposed on one another interconnected to form a pouch which is open on one side for insertion of electrode plates. Background technique [0003] It is known to use separators in rechargeable batteries to electrically separate electrode plates of opposite polarity...
