Title (EN) SEPARATOR FOR STARVED ELECTROLYTE LEAD/ACID BATTERY
(FR) SEPARATEURS POUR ACCUMULATEURS PLOMB/ACIDE A ELECTROLYTE RESTREINT
Abstract: front page image
(EN)Compositions and papers made therefrom useful as separator materials in starved electrolyte lead/acid batteries. The compositions comprise a mixture of 30 percent to 80 percent by weight of perlite and 20 percent to 70 percent by weight of glass fibers. The glass fibers have diameters in the range of from 0.3 to 1.0 micrometers while the perlite has particle sizes in the range of from about 3 to about 100 micrometers. Higher tensile strength papers are formed from an embodiment in which the compositions comprise a mixture of 15 percent to 75 percent by weight of perlite, 20 percent to 70 percent by weight of glass fibers and 5 percent to 20 percent by weight of acid-insoluble thermoplastic fibers, the latter preferably in the form of staple fibers.
(FR)Compositions et des papiers prepares a partir de celles-ci utiles en tant que separateurs dans des accumulateurs plomb/acide a electrolyte restreint. Les compositions comprennent un melange de 30% a 80% en poids de perlite et de 20% a 80% en poids de fibres de verre. Les fibres de verre ont des diametres compris entre 0,3 et 1,0 micrometres, tandis que la perlite possede des dimensions de particules d"environ 3 a environ 100 micrometres. Des papiers a plus forte resistance a la traction sont formes a partir d"une forme d"execution dans laquelle la composition comprend un melange de 15%, a 75%, en poids de perlite, 20 a 70%, en poids de fibres de verre et 5% a 20% en poids de fibres thermoplastiques insolubles dans l"acide, ces dernieres etant de preference sous forme de fibres discontinues.
