Separator
A separator for an electrode plate of a plate-shaped electrode of a battery, particularly a lead-acid battery, comprising a separator pocket providing a receiving space for said electrode plate and including two separator sheets bearing on each other, which are welded to each other along their respective longitudinal sides and upper front sides, the welding seam interconnecting said upper front sides presenting an interruption, which forms a recess for a current-collecting lug disposed on the upper outer edge of the electrode plate to pass through, said welding seam, for forming a degasification opening, being interrupted in a rim portion adjacent to a longitudinal side, a second welding seam spaced from said welding seam being provided which is positioned directly vis-à-vis the degasification opening of the first welding seam. |

Middle or large-sized battery module
A middle- or large-sized battery module includes two or more unit modules each having one or more plate-shaped battery cells, as unit cells, surrounded by a high-strength sheathing member made of synthetic resin or metal, and separable upper and lower frame members coupled with each other in an assembly-type coupling structure such that the unit modules are vertically mounted in the upper and lower frame members. A sensing unit capable of minimizing the weight and size of battery cells is easily mounted while effectively reinforcing the low mechanical strength of the battery cells and sensing the operation state of the battery cells to a middle- or large-sized battery module. The battery module is manufactured by a simple assembly process without using a plurality of members for mechanical coupling and electrical connection. |
