れて脱落し易くなる問題がある。When the conventional ribbed separator is incorporated into an electrode plate group to constitute a lead storage battery, expansion of the anode plate due to charge and discharge during use thereof,
Deformation due to shrinkage, etc., due to the curvature of the flat thin base portion of the separator without any ribs, the base portion of the thin sheet of the separator comes into contact with the anode surface, and lead oxide is the active material of the electrode plate. There is a disadvantage that it is oxidized to cause oxidative deterioration, and finally holes are formed, resulting in a short circuit between the electrode plates and a shortened battery life. In order to prevent this, it is conceivable to make the height of the rib extremely high, but this has a disadvantage that the distance between the rib and the electrode plate surface becomes large and the electric resistance increases. In addition to the ribbed separator, in order to prevent oxidative deterioration of the separator, a glass matted separator obtained by polymerizing a glass mat on a flat thin separator surface has been proposed. This leads to an increase in manufacturing cost. Also, since the binder is mixed in the glass fiber,
When incorporated in the electrode plate group, there are disadvantages that the electrical resistance increases and the discharge characteristics of the battery deteriorate. Then, in view of such a conventional technique, the present applicant has previously
In the utility model registration application No. 78680, at least a mini-rib having a height lower than that of the main ribs is provided at least between adjacent main ribs of a ribbed separator provided with a large number of main ribs at intervals on the thin sheet base surface. By providing one strip, even if the anode plate or the separator is deformed during use of the battery, it is possible to prevent the base portion of the separator from directly contacting the anode plate surface by contacting the anode plate surface with the mini-rib. A ribbed separator was proposed. However, in this separator, the cross-sectional shape of the mini-rib is trapezoidal, the upper surface is completely flat, and the surface from the upper surface to the side wall surface is formed into an angular surface. Therefore, deformation due to expansion and contraction of the anode plate due to charge and discharge,
When the anode plate surface comes into contact with the mini-ribs due to the curvature of the flat thin base portion having no ribs, the active material on the surface of the anode plate is easily scraped off by the angular surface of the mini-ribs, which makes it easy to fall off. .

ができる。Thus, when the above-mentioned mini-ribbed separator is incorporated into the electrode plate group to form a lead storage battery, the electrode plate is deformed due to expansion and contraction due to charging and discharging during use, and the separator has a thin base portion. Even if bending occurs, the mini-rib provided near the center between the main ribs of the separator prevents the base portion of the thin sheet from coming into contact with the electrode plate surface, and oxidation deterioration of the sheet is prevented in advance. As a result, an internal short circuit is prevented and the battery life is extended. In particular, since the radius is provided along the long side of the upper surface of the mini-rib, when the electrode plate contacts the mini-rib, it is possible to prevent the active material of the electrode plate from falling off by the edge of the upper surface of the mini-rib, The battery life can be extended.
