Abstract:
A porous framework plate for an electrode or recombination element in an electric accumulator, comprising:a piece of metallized fiber material made of synthetic fibers which are intrinsically electrically non-conductive and have a metal coating, said material being selected from the group consisting of a nonwoven material and a needle felt, and being cut to a predetermined size for said electrode or recombination element, said predetermined size being defined by edges including an edge area for attachment of a current tapping tab;wherein, to alleviate failures of said electrode or recombination element due to possible metallized fibers projecting from edge areas of the framework plate and possible growth of dendrites, substantially all remaining edge areas of said framework plate outside of said edge area for attachment of a current tapping tab, are characterized by compression of edge areas thereof relative to surfaces of said frame work plates outside said edge areas.
