Title
(EN) SEPARATOR FOR CLOSED TYPE LEAD-ACID BATTERY
(FR) SEPARATEUR POUR BATTERIE AU PLOMB DU TYPE FERME
Abstract
(EN)
A separator for a closed type lead-acid battery comprises a porous mat manufactured by a method wherein polyolefine synthetic pulp as its main component is mixed with a binder of a melting point lower than that of the synthetic pulp, the mixture is made into paper, and the paper is heat-treated at a temperature lower than the melting point of the synthetic pulp and higher than the melting point of the binder. The separator is cheap as no glass fiber is used, excellent in water retention and acid resistance, and has a low density. Closed type lead-acid batteries using this separator are excellent in capacity of discharging at a high rate at a low temperature.
(FR)
Un séparateur pour une batterie au plomb du type fermé comprend un matelas poreux que l'on produit en mélangeant, en tant que composant principal, une pâte synthétique de polyoléfine avec un liant dont le point de fusion est inférieur à celui de ladite pâte synthétique, en transformant le mélange obtenu en papier, puis en traitant thermiquement le papier à une température inférieure à celle du point de fusion de la pâte synthétique et supérieure au point de fusion du liant. Le séparateur est bon marché étant donné que l'on n'utilise pas de fibre de verre, il présente des propriétés excellentes de rétention d'eau et une grande résistance à l'acide, et sa masse volumique est faible. Les batteries au plomb du type fermé comprenant un tel séparateur ont une grande capacité de décharge à haute intensité, à basse température.
