Abstract

PURPOSE:To provide a low cost and high performance separator by forming a separator to be placed between a positive plate and a negative plate by mixing synthetic fibers having acid resistance and oxidation resistance and inorganic fine powder having oxidation resistance in a specified ratio. CONSTITUTION:1.30-3wt% of synthetic fibers of each of polypropylene fibers, polyester fibers, or acrylic fibers or these mixtures and 2.70-97wt% of silica powder as an inorganic powder are dispersed in water and made in a paper-like sheet with paper making equipment to form a separator to be placed between a positive plate and a negative plate. The synthetic resin 1 gives the separator strength, and supports inorganic fine powder 2, and makes voids wherein electrolyte is not hold. The inorganic fine powder 2 holds electrolyte and prevents short between plates. This separator substantially decrease cost compared with a conventional glass separator.

Description

【発明の詳細な説明】 本発明は密閉形鉛蓄電池に関するものであり。[Detailed description of the invention] The present invention relates to a sealed lead acid battery.

安価で寿命性能が優れ、使用中に電解液の減少が少ない
保守の不要な密閉形鉛蓄電池を提供することを目的とす
るものである。The object of the present invention is to provide a sealed lead-acid battery that is inexpensive, has excellent life performance, reduces electrolyte loss during use, and requires no maintenance.

が上昇するという欠点を有していた。Recently, this type of lead-acid battery has a 4#i fiber diameter of 0.2.
~5μml! A separator using a mat-like separator made of i-degree fine short glass fibers has been put into practical use and has shown excellent performance. However, this type of fine glass fiber is expensive, and batteries using it have the disadvantage of increasing the price of lead-acid batteries.

該酸化珪素が直接作用することがなく。For this reason, various proposals have been made to obtain inexpensive separators. For example, in Japanese Patent Publication No. 42-8402, paper is made by beating glass fibers using a water-containing amorphous silicon oxide powder as a paper-making liquid, and after incomplete drying, it is made into an acid- and oxidation-resistant resin suspension or solution. A diaphragm body that is soaked, dried, and heat-treated has been proposed. However, this l? In the Im body, the silicon oxide is fixed with the abrasion-resistant resin, so the silicon oxide does not directly act on the electrolyte.

よって特に電解液の量を制限したいわゆる密閉形鉛蓄電
池に適用した場合、液枯れが発生するという欠点がある
。Therefore, especially when applied to a so-called sealed lead-acid battery in which the amount of electrolyte is limited, there is a drawback that liquid depletion occurs.

。Furthermore, in Japanese Patent Publication No. 47-40753, fiber diameters of 4 to 10
A microporous layer of fibers is formed on the glass mat by dispersing μ glass fiber strips and thus much finer mineral fiber strips in appropriate proportions of water and letting it flow down onto the glass mat. However, in a separator constructed in this way, the upper microporous layer peels off from the glass mat and separates into two layers, and the pores have a large pore size that increases the retention and absorption of the electrolyte. It has the disadvantage of being insufficient. Furthermore, when this separator is used in a sealed FL# battery, the electrolyte absorption rate between the microporous layer and the glass mat is extremely different, causing uneven distribution of the electrolyte within the battery and shortening the battery life. It has a major drawback of being extremely short.

に対し。The object of the present invention is to provide a sealed lead-acid battery that is inexpensive and has performance comparable to that of conventional batteries using fine glass fibers. A separator composed of 60 to 3% by weight of synthetic fibers having multiple types of acid resistance and oxidation resistance, and 70 to 97% by weight of inorganic fine powder having acid resistance,
It is characterized by being placed between a positive electrode plate and a negative electrode plate. That is, whereas the conventional separator made of fine short glass fibers in the form of a mat is mainly composed of glass fibers and essentially holds the N waste liquid in the spaces between the glass fibers.

Synthetic fibers made of nominally 3 denier acrylic fibers alone or in combination, and silica powder or diatomaceous earth as inorganic fine powder are dispersed in water and formed into paper using a paper machine to form a paper with a thickness of 20#/dA under a load of 20#/dA. A separator with a diameter of 1.5 was obtained. Table 1 shows the blending ratio (weight ratio to the separator) of the materials constituting the prototype separator, as well as its properties and cost. For comparison, the characteristics of a conventional separator made of 100% fine glass fibers with a fiber diameter of 0.5 to 1.0 μm are also listed.The cost of each separator is compared to the conventional separator.

および引張強度は約１１９Ａｄ以上であることが硝まし
いことを我々は経験的に知得している。The characteristics required for a separator for a sealed lead-acid battery are a porosity of approximately 75% or more and a liquid content of approximately 2ccH2804/dr.
y 5apa, (4 or more, maximum pore diameter is about 30μ or less,
We have learned from experience that a tensile strength of about 119 Ad or more is desirable.

If it is less than 0%, the porosity is small, and if it is more than 97%, the tensile strength decreases, which is not suitable for practical use.

じみが悪いことから、ｉａ電解液保持しない空隙が多く
なり易く。As is clear from Table 2, the enemy of 9 synthetic fibers is 50% by weight.
The sealed lead-acid battery E, which was more common, had a shorter lifespan and a higher rate of liquid loss. This is because the synthetic fibers and the electrolyte generally do not fit well, which tends to result in a large number of voids that do not hold the IA electrolyte.

従って試験開始初期に見掛は玉保持されていた電解液が
寿命試験中に消失し電解液比重が上ったため正極格子体
の腐蝕が促進され寿命が短かくなったと考えられる。Therefore, it is thought that the electrolytic solution that was apparently holding beads at the beginning of the test disappeared during the life test, and the specific gravity of the electrolyte increased, which accelerated the corrosion of the positive electrode grid and shortened the life.

率が少なくなるという効果を示したものとｍ察される。On the other hand, if the amount of synthetic fibers is less than 30% by weight, voids are created in the separator that do not hold an appropriate amount of electrolyte, and as a result, the rn violet gas generated at the positive electrode plate is It is thought that this is because it becomes easier for the liquid to pass through and reach the negative electrode plate, thereby reducing the liquid reduction rate.

なお。In addition.

電池Ｆは性能が良いが、第１表に示した如く。Battery F has good performance, as shown in Table 1.

隔離体の引張強度が弱すぎるため、実際の電池生産を考
えた場合、ｍ立ができず実ｍにならない。Since the tensile strength of the separator is too weak, when considering actual battery production, it is impossible to stand up and make an actual battery.

以上のごとく本発明における隔に体では、その構成材料
である合成繊維は隔離体に必要な強度を与え、かつ上記
無機微粉末を支持する役目。As described above, in the separator of the present invention, the synthetic fibers that constitute the separator have the role of providing the necessary strength to the separator and supporting the inorganic fine powder.

さらには電ＩＷ液を保持しない空隙を作る役目を果し、
他方、無機微粉末は所望の電解液を保持するとともに、
正極板と負極板との短絡を防止する役目を果すものであ
る。Furthermore, it plays the role of creating voids that do not hold the electric IW liquid,
On the other hand, inorganic fine powder retains the desired electrolyte and
This serves to prevent short circuits between the positive electrode plate and the negative electrode plate.

それゆえ合成繊維としては、その形状としてフィブリル
化されている方が見掛は密度が高くない点で好ましく、
その繊維径は細い方が多孔度が高くなる点で鍾ましい。Therefore, as a synthetic fiber, it is preferable to have a fibrillated shape because it does not have a high apparent density.
The smaller the fiber diameter, the higher the porosity.

またその長さは約５１１ｍ以上の方が強度が高くなる点
で象ましいが。Moreover, it is impressive that the length is about 511 meters or more because the strength is higher.

機繊維を少量混合してもよい。The type is not particularly limited. Of course, a small amount of inorganic fiber may be mixed for manufacturing reasons without departing from the spirit of the present invention.

また無機微粉末としては、耐酸、耐酸化性を有し、電解
液の濡れ性に優れたものであればよく。Further, the inorganic fine powder may be any powder as long as it has acid resistance, oxidation resistance, and excellent wettability with electrolyte solution.

い。The type is not particularly limited, but those with small particle size can reduce the pore size, but it is difficult to obtain porosity.
On the other hand, if the particle size is large, it is easy to obtain porosity, but the pore size tends to be large. Therefore, it is desirable to use a mixture of particles with a suitable particle size of 0.01 μm to 20 μm. Furthermore, a binder may be used within a range that does not impair battery performance.

また隔離体の製法としては実施例では抄紙法によるもの

お隔離体の生産において。In addition, as the method for manufacturing the separator, although a paper making method is described in the Examples, the method is not limited to this method. Furthermore, in the production of separators.

When the amount of a-fibers is small, it is often preferable to heat the uncollected particles without applying pressure in order to fix the inorganic particles and improve the handleability of the separator.

のである。As mentioned above, the present invention uses an inexpensive and conventional fine glass fiber as a separator by using a separator in which the synthetic fibers are blended to 30 weight ff11 or less with respect to the separator, and the remainder is inorganic fine powder. It is possible to obtain battery performance similar to that of conventional batteries, and its industrial value is great.
