Abstract

Electrode for electrochemical current sources, esp. accumulators, using a mixt. of an active mass and a plastic, together with a collector, i.e. for the current. The surface of the electrode is at least partially covered by a porous layer of an electric insulating material which is chemically inactive and unaffected by the electrolyte, esp. a woven textile fabric, the insulant being sintered together with the mixt. of the active material and the plastic to form one unit. Used in lead accumulators, but may also be used in other cells, e.g. alkaline accumulators. Prevent the active material from floating out of the electrode, producing increased reliability and permitting repeated overloading of the battery during operation; the working life of the battery is increased many times.
