摘要： There is disclosed a novel cell separator made of a grafted membrane comprising a polyethylene film which is graft-copolymerized with a monomer having an ion exchange group, characterized in that said membrane has an area which is not grafted at all or an area of low degree grafting. By making use of this membrane, a small size and thin cell having excellent performance as well as satisfactory mechanical strength can be produced at low cost with great advantages.

摘要： A novel process for the production of a separator for use in a cell to prevent the short-circuiting of positive active material and negative active material comprises irradiating a polyolefin film 150 .mu.m or less thick with ionizing radiation at a dose rate of 5.times.10.sup.4 -10.sup.7 rads/sec. to give a total dose of 1 Mrad or more, contacting the irradiated film with an aqueous solution of a terminally unsaturated monomer such as acrylic acid, methacrylic acid and the like at a temperature of 10.degree. C.-60.degree. C. to thereby cause grafting of the monomer onto the polyolefin film before the grafted polymer film is treated with an aqueous alkaline solution to finally obtain the separator for use in a cell, which is substantially improved in that it shows low electrical resistance and is excellent both in its acid resistance and mechanical strength.

摘要： A battery separator composed of a composite sheet of film to which a monomer having a hydrophilic or electrolytic group is grafted is disclosed. Said film consists of a first polymeric layer containing a substance capable of catching a metal ion dissolved from a positive or negative active material and a second polymeric layer integrally bonded to either one or both sides of the first polymeric layer and which contains no such substance or contains it in a smaller amount that that contained in said first polymeric layer. Also disclosed is a method of producing a battery separator by irradiating such composite sheet of film with ionizing radiation and immersing the irradiated film in a solution of a monomer containing a hydrophilic or electrolytic group or bringing it into contact with the monomer solution to thereby graft the monomer to the film.

摘要： A sodium-sulfur storage battery having a sealed housing which contains a solid electrolyte incorporating an anodic reactant such as sodium, a cathodic current collector (which may be the housing) extending in a direction generally parallel to the solid electrolyte and cathodic electro-conductive material disposed between and in contact with the solid electrolyte and the cathodic current collector. The cathodic electro-conductive material is impregnated with a cathodic reactant and includes a fiber content, the individual fibers of which have a direction normal to the direction of the cathodic current collector. One suitable material for the cathodic electro-conductive material is a graphite felt and which is impregnated with sodium polysulfide or sulfur.
