Реферат: 879,871. Batteries. SOC. DES ACCUMULATEURS FIXES & DE TRACTION. Jan. 28, 1958 [Feb. 20, 1957], No. 2871/58. Drawings to Specification. Class 53. An alkaline accumulator having electrodes of agglomerated metal particles impregnated with active material is provided with separators each comprising three layers, the outer layers being of high permeability, and the middle layer of low permeability. The layers may consist of gels having different permeabilities, or the middle layer may be of regenerated cellulose, the outer layers consisting of non-woven fabrics, e.g. fibres united by a binder. The layer in contact with the positive electrode may be made of a cellulosic non- woven fabric, the layer in contact with the negative electrode being of a non-woven synthetic resin fabric, for example a fabric made from vinylic material fibres. The three layers may be united by sewing, and they may be folded in concertina fashion. The electrodes may comprise perforated metal sheets coated on both sides with sintered nickel particles impregnated with nickel hydroxide with or without cobalt hydroxide, and cadmium hydroxide. The stack of electrodes and separators is forced tightly into a casing and impregnated under vacuum with a solution of potassium hydroxide. The cellulosic parts of the separators swell and put the stack under pressure. No gas is evolved during charging, but when fully charged the battery liberates gas and the voltage rises sharply. Specifications 715,903 and 855,812 are referred to.
