PURPOSE:To give electrolyte stirring effect and increase life by embedding a porous glass sheet having a specified net-cross section area on the surface of a positive plate, and facing the positive plate with a negative plate with a separator having ribs on both sides interposed. CONSTITUTION:A vibration resistant paste type lead-acid battery is formed in such a way that a porous glass sheet 6 having a net cross section area of 0.0016-4.0mm.<2> is embeded on the surface of a positive plate 1, and the positive plate 1 is faced with a negative plate 4 with a separator 3a having ribs or grooves on both sides interposed, and they are accommodating into a container 5 by applying pressure. By specifying net cross section area of the porous glass sheet 6, gas evolved in charging is smoothly exhausted and guided upward by ribs of the separator 3a to stir electrolyte. Since peeling off of active material is prevented, cycle life is increased. |
