VALVE-REGULATED LEAD-ACID CELLS AND BATTERIES AND SEPARATORS USED IN SUCH CELLS AND BATTERIES

Lead-acid cells and batteries, particularly valve-regulated lead-acid cells and batteries (50), are disclosed, which utilize absorptive glass mat separators (58) modified by treatment with appropriate polymers. Suitable polymers include hydrophobic polymers, such as polyolefins, polytetrafluoroethyl...

description	Lead-acid cells and batteries, particularly valve-regulated lead-acid cells and batteries (50), are disclosed, which utilize absorptive glass mat separators (58) modified by treatment with appropriate polymers. Suitable polymers include hydrophobic polymers, such as polyolefins, polytetrafluoroethylene, polyvinylchlorides, polyacrylonitriles, and polyesters; amphiphilic block and graft copolymers having both hydrophobic and hydrophilic properties; and hydrophilic nitrogen-containing polymers such as polyvinylpyrrolidones. A valve (68) is used to regulate internal gas pressure. On décrit des piles et des accumulateurs au plomb-acide et plus particulièrement des accumulateurs (50) et des piles au plomb-acide régulés par valve dans lesquels ont utilise des séparateurs (58) à mat de verre absorbant modifiés par un traitement avec des polymères appropriés. Les polymères appropriés peuvent être des polymères hydrophobes, tels que des polyolefines, du polytétrafluoroethylène, des chlorures de polyvinyl, des polyacryonitriles et des polyesther; des copolymères blocs et greffés amphiphiles présentants des propriétés à la fois hydrophobes et hydrophiles; et des polymères contenant de l'azothe hydrophile tels des polyvinyles pyloridones. Une valve (68) permet de réguler la pression interne du gas.
