ABSTRACT:
The invention concerns a sheet material and separator envelopes manufactured therefrom for enclosing electrode plates of batteries. The cited object is to improve the manufacturability of the heat-sealed or bonded seams of the electrode envelopes and to prevent puncturing or rupturing of the separator envelopes due to growth of the positive grid. This object is achieved by means of a base-sheet thickness for the sheet material used to manufacture the separator envelopes which is greater in the region of the marginal areas than in the region of the inner surface of the sheet material or separator envelopes.
