摘要： A high efficiency lead acid battery with liquid electrolyte for the Stop &Start cycle (10),especially suitable for equipping hybrid-electric class vehicles, comprises a container body or monobloc (12) in plastic material sub-divided internally into a plurality of cells (14) in which one or more negative plates or electrodes (28) and one or more positive plates or electrodes (22) are positioned, immersed in an electrolyte and delimited by porous separators; the electrodes (22-28) are electrically connected, between the various cells (14) constituting the monobloc by means of electrode/electrode and cell/cell connection elements (40). Said battery further comprises a cover (16) which closes so as to hermetically seal the container body (12), is fitted with plugs (20) which close the accesses to the cells (14) and incorporates the truncated cone terminals (18).The separator, positioned between the different electrodes, alternatively positive and negative (22-28), is formed of two overlaid layers (24), (26), the first of which outermost in relation to the positive electrode (22) and made of polyethylene, while the second and innermost layer (26) in relation to said positive electrode is made of non woven polyester having a thickness of 0.1 to 1.0 mm at 5 kPa.
The containment layer of each negative plate or electrode (28) is composed of stratified, polyester-based non woven, present in a quantity of not less than 60%.
