Abstract

A separator (1) for electrode plates (2) in gel storage batteries having two substantially rectangular layers (3, 3′) of a flat separator material, which layers come to lie in mutually superposed relationship. In order to provide less expensive separators for the separation of plate electrodes in gel storage batteries, which have a low electrical resistance and which afford additional protection for the edges and side surfaces and at the same time permit homogenous gel filling of the storage battery, the invention proposes that the two layers of separator material are connected together at least portion-wise in the region of their edges, forming a casing or pocket for the introduction of an electrode plate and a method and battery employing the separator.
