Title
(EN) A SPACING ELEMENT FOR LEAD GEL BATTERIES OR FOR LEAD-ACID BATTERIES
(FR) ÉLÉMENTS D'ESPACEMENT POUR BATTERIES PLOMB-GEL OU POUR BATTERIES ACIDE-PLOMB
Abstract
(EN)
Spacing element for lead batteries with gel electrolyte or for lead-acid batteries, comprising at least one layer of non-woven fabric made from fibers of one or more organic polymers suitable to absorb said electrolyte. Said layer will be associated to a separating element placed between the two electrodes of inverse polarity. The present invention relates to a lead gel battery as well as a spacing element for lead-acid batteries, both equipped with spacing elements according to the invention.
(FR)
L'invention concerne un élément d'espacement destiné à des batteries au plomb avec un électrolyte gel ou pour des batteries acide-plomb, comprenant au moins une couche de tissu non tissé fabriqué à partir de fibres d'un ou de plusieurs polymères organiques qui conviennent pour absorber cet électrolyte. Cette couche sera associée à un élément de séparation placé entre les deux électrodes de polarité inverse. L'invention concerne une batterie plomb-gel ainsi qu'un élément d'espacement pour des batteries acide-plomb, toutes les deux équipées d'éléments d'espacement de l'invention.
