る。Conventional technology The conventional liquid fixation method for sealed lead-acid batteries is as follows:
The micro glass mat separator made of fine glass fibers with an average fiber diameter of about 1μ holds a liquid electrolyte, and the gel method uses a gel electrolyte. There is a combination method that uses a separator and a gel electrolyte. In addition, as the combination method, there are those that use a fine glass mat as the separator, and those that use separators such as sintered PVC or paper separators used in so-called flowing electrolyte type lead-acid batteries.

持性に欠け短寿命であるという欠点が有つた。Problems to be Solved by the Invention However, among these combination systems, those using fine glass mats have the disadvantage that the fine glass mats are expensive and the field of use thereof is limited. In addition, among the combined methods, in those using separators used in so-called flowing electrolyte type lead-acid batteries, the separator has a high density and a low porosity of about 60%, so the amount of electrolyte retained is small, resulting in a decrease in battery capacity. There is a problem that it is inferior,
Furthermore, since the separator has poor elasticity, it has a short lifespan due to poor retention of the active material.

In other words, the positive electrode plate 2 has a sulfuric acid group in advance before assembly.
The ceramic fibers and the three negative electrodes are made of ceramic fibers with a composition of 52% silica (SiO 2 ) and 47% alumina (Al 2 O 3 ), and an average fiber diameter of 2.5μ. A pole group was obtained by stacking them with a separator using pine interposed therebetween. The size of this positive electrode plate and negative electrode plate is the height of each

The electrolyte was allowed to gel. Thereafter, a top cover with a valve was attached to the battery case and the battery was charged, completing a sealed lead-acid battery according to the present invention.

ても安定であり、ゲル化が均一になり安いものと
思われる。 The possible reasons for this are as follows. In other words, the ceramic fibers used as separators in sealed lead-acid batteries a have an average fiber diameter of about 2 to 4 μm, which is thicker than the 1 μm or less diameter of fine glass mats, but when combined with a gel-like electrolyte, This is thought to be because it has the same function as the other. In addition, cheap ceramic fibers contain shot (non-fibrous particles), but these particles have a larger particle size than the silicon dioxide used to gel dilute sulfuric acid, so silicon dioxide does not gel. This prevents the resulting silica skeleton structure from becoming too dense, giving favorable results to battery performance. This is because if this skeletal structure becomes too dense, it will be difficult to secure a passage for gas movement, and it will also be difficult for electrolyte to move, which will adversely affect the capacity and life performance of the battery. Furthermore, ceramic fiber contains CaO, MgO, B 2 O 3 , Na 2 contained in glass fiber.
It does not contain metal oxides such as O, is stable against acids, and is thought to be uniformly gelled and inexpensive.
なお上記実施例１ではペースト式の密閉形鉛蓄

いほうが望ましい。 Furthermore, when processing ceramic fiber into a plate shape to make a separator, it is conceivable to use an organic or inorganic binder, but in order to have excellent elasticity and high porosity, it is preferable not to use these.
