Metallized fiber structure framework having treated edge surfaces and faces for use as an electrode or recombination element in accumulators

摘要

The invention provides a treatment for edge surfaces and faces of metallized fiber structure framework plates for use in electric accumulators. The edge surfaces and faces, except for the starting portion of the current tapping tab, are mechanically, thermally or chemically freed of projecting metallized fiber ends and fiber bundles in order to avoid short circuits or soft shorts caused by dendrites penetrating the cell separator or by metallized fiber ends. The mechanical, thermal or chemical treatments can take place individually or in combination with one another.
