The present invention provides a separator for non-aqueous electrolyte batteries which neither breaks nor slips off at the time of fabrication of battery, gives excellent battery fabricability, causes no internal short- circuit caused by contact between electrodes even if the electrodes are externally short-circuited, can inhibit ignition of battery and produces high energy density and excellent cycle life, and further provides a non-aqueous electrolyte battery using the separator and a method for manufacturing the separator. That is, the present invention relates to a separator for non-aqueous electro- lyte batteries which comprises a porous base containing at least one member selected from a porous film, a woven fabric or nonwoven fabric containing an organic fiber and a paper and an organometallic compound applied to the porous base; a method for the manufacture of the separator for non-aqueous electrolyte batteries which comprises allowing said porous base to contact with a solution of organo- metallic compound by impregnation, coating or spraying, followed by drying or curing with heating to apply the organometallic compound to the porous base; and a non- aqueous electrolyte battery using the separator.
L'invention porte sur un séparateur pour batteries à électrolyte non aqueux ne subissant ni dommages ni déplacements lors du montage de la batterie et facilitant ce même montage, protégeant contre les courts-circuits internes dus au contact entre électrodes même si les électrodes sont court-circuitées à l'extérieur, empêchant les batteries de s'enflammer, et assurant une haute densité d'énergie et une longue durée de vie. La fabrication dudit séparateur s'opère par collage d'un composé organométallique sur un substrat poreux contenant un ou plusieurs matériaux choisis parmi un film poreux, des tissus de fibres organiques, des non tissés et du papier. Le procédé de fabrication consiste à mettre en contact une solution du composé organométallique avec le substrat poreux, par immersion, enduction ou pulvérisation, puis à y faire adhérer le composé organométallique par séchage ou durcissement thermique.
