Abstract

Cover sheath for the active material of an electrical accumulator consists of a combination of (I) a porous layer of nonwoven textile contacting the active material, and (II) an external support for (I) consisting of monofilaments or highly twisted continuous fibres. Both (I) and (II) pref. consist of synthetic fibres. Sheath combines mechanical strength with satisfactory porosity.
