METHOD OF REPAIRING BATTERY SEPARATORS |
摘要 |
<p>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.</p> |
