ALKALI-AKKUMULATOR MIT BIPOLARER ELEKTRODE UND VERFAHREN ZU DESSEN HERSTELLUNG

摘要

Setting the alkaline accumulator elements, particularly of the nickel-cadmium type or of the nickel-hydrides type, in series, is achieved by means of a bipolar collector, a metal strip of nickel or nickelled steel. The negative (10), positive (20) electrodes are obtained respectively by plating on each face of the strip (30) a bidimensional structure of foam or felt of nickel, and by filling them with active materials. The tridimensional structure provides both for the collection of charges and the retention of active materials.
