摘要
An aqueous cadmium oxide paste of high flowability for the vibration filling of foam-structure and fiber-structure electrode plaques is characterized by a cadmium oxide content of about 25 to 35% by volume, a pH of about 10 to 12.5, a content of about 0.5 to 2.5% by weight, based on cadmium oxide, of one or more dispersants from the group comprising the water-soluble salts of polyphosphoric acids, di- and polyphosphonic acids and their derivatives, gluconic acid or of antimonyl tartrate. The paste has a plastic viscosity of about 0.1 to 1 Pa.s and also a yield value of between about 10 and 120 Pa. This cadmium oxide paste makes it possible to fill foam-structure and fiber-structure electrode plaques completely in one operation.
