摘要: The invention relates to microporous battery separators based on an essentially homogeneous mixture of a thermoplastic polymer, an inert filler and optionally a plasticizer. The separators contain, as filler, pyrogenic silica in a quantity of more than 20 vol. % and optionally one or more further fillers, so that the filler content overall is more than 60 up to a maximum of 82 vol.-%. The separators are suitable in particular for the manufacture of sealed accumulators.

摘要: Process for repairing manufacturing defects in porous separator webs for accumulators in which a repair material is deposited in targeted manner onto the defect in-line repair as production of the separator web proceeds and the defect is thus sealed, or in which the defect is heated in-line at certain points and thereby welded. Suitable as repair materials are in particular polymers and/or resins dispersible in a dispersion agent, polymerizable materials and hot-melts. Welding preferably takes place using ultrasonics.
