【発明の詳細な説明】
産業上の利用分野
本発明は自動車のエンジン始動などに用いられる鉛蓄電
池に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lead-acid battery used for starting an automobile engine, etc.
従来の技術
鉛蓄電池の内部は陽極板、陰極板およびそれらを隔離す
るセパレータ等で構成される。The interior of a conventional lead-acid battery is composed of an anode plate, a cathode plate, a separator separating them, and the like.
このなかでセパレータに合成樹脂を主成分としたフィル
ム状微多孔膜を用いるものである。このセパレータは極
板を包みこむように折り曲げて側面をシールして袋状に
して用いられるのが一般的である。Among these, a film-like microporous membrane whose main component is a synthetic resin is used as a separator. This separator is generally used in the form of a bag by bending it so as to wrap around the electrode plate and sealing the sides.
このため陽極板と陰極板とが完全に遮蔽され、長期使用
後に、たとえば陽極活物質が軟化して脱落しても内部短
絡しない。このため従来セパレータと必ず併用し陽極活
物質を保持していたガラスマットは、省略されるのが一
般的である。Therefore, the anode plate and the cathode plate are completely shielded, and even if, for example, the anode active material softens and falls off after long-term use, there will be no internal short circuit. For this reason, the glass mat, which was conventionally always used in combination with the separator to hold the anode active material, is generally omitted.
そしてガラスマットが省略された部分は空隙となるが、
その部分にはフィルム状セパレータの一部にリブをもう
けて極板とセパレータ間の距離を確保するのが一般的で
ある。And the part where the glass mat is omitted becomes a void,
Generally, a rib is provided in a part of the film-like separator to secure the distance between the electrode plate and the separator.
この場合、リブは一般的に陽極板と相対するように設け
られる。これは陽極の充放電反応においては水の生成、
消費反応が関与するため、電池の初期容量、特に急放電
持続時間を確保するのに有利なようにである。In this case, the ribs are generally provided opposite the anode plate. This is due to the generation of water in the charge/discharge reaction of the anode.
Since a consumption reaction is involved, it is advantageous to ensure the initial capacity of the battery, especially the rapid discharge duration.
発明が解決しようとする課題
陽極にアンチモンを含まない電池は、自己放′市および
使用中の減液が少ないという特徴があるが、一般にアン
チモンを用いた電池にくらべて深い充放電における寿命
が短かいとされている。Problems to be Solved by the Invention Batteries that do not contain antimony in their anodes are characterized by less self-release and less liquid loss during use, but they generally have a shorter lifespan during deep charging and discharging than batteries that use antimony. It is said to be important.
本発明は陽極板の格子合金にアンチモンを含まない電池
のこの短所を改善することを目的とする。The present invention aims to improve this disadvantage of batteries that do not contain antimony in the lattice alloy of the anode plate.
課題を解決するための手段
この問題点を解決するための手段として、本発明では先
に述べたように従来陽極板に接するように配置されてい
たセパレータのリブを陰極に接するように、又リブのな
い面を陽極板に接するようにし、袋状セパレータとして
陽極板又は陰極板を包むように構成したものである。Means for Solving the Problem As a means for solving this problem, in the present invention, as mentioned above, the ribs of the separator, which were conventionally arranged so as to be in contact with the anode plate, are changed so that the ribs are in contact with the cathode, and the ribs are The surface without the ridge is in contact with the anode plate, and the bag-shaped separator is configured to wrap around the anode plate or the cathode plate.
作 用
先に述べた陽極板の格子合金にアンチモンを用いない電
池における深い充放電のくりかえしで寿命が短かい理由
は、充放電をくりかえすうち、陽極活物質の粒子間の結
合が弱くなり、充放電反応が格子活物質界面近傍のみで
しかおこらないことによる。The reason why batteries that do not use antimony in the lattice alloy of the anode plate described above have a short life due to repeated deep charging and discharging is that as the batteries are repeatedly charged and discharged, the bonds between the particles of the anode active material become weaker and the charging This is because the discharge reaction occurs only near the interface of the lattice active material.
この現象は特に陽極板近傍の電解液(稀硫酸)濃度が高
い程顕著である。This phenomenon is particularly noticeable as the electrolyte (dilute sulfuric acid) concentration near the anode plate increases.
本発明ではセパレータを陽極板に密着させるようにする
ことにより陽極板への電解液の供給を抑制して陽極近傍
の電解液濃度を低下させてこの現象を緩和するものであ
る。In the present invention, this phenomenon is alleviated by bringing the separator into close contact with the anode plate to suppress the supply of electrolyte to the anode plate and reduce the concentration of the electrolyte near the anode.
実施例 以下実施例により本発明について説明する。Example The present invention will be explained below with reference to Examples.
鉛−カルシウム−錫合金からなるエキスバンド加工した
格子を用いて陽陰極板を常法により作製した。Anode and cathode plates were fabricated by a conventional method using an expanded grid made of a lead-calcium-tin alloy.
このうち陽極板は次の2通りとした。その一つは第1図
aに示すように従来通りリブ2に極板が接するよう袋状
セパレータ3で包みこんだ。なお4はシール部である。Among these, the following two types of anode plates were used. In one of them, as shown in FIG. 1a, the rib 2 was wrapped in a bag-like separator 3 so that the electrode plate was in contact with the rib 2 as in the past. Note that 4 is a seal portion.
もう一方は第1図すに示す本発明の例でありリブ2のな
いセパレータ3表面が極板1と接するように極板を包み
こんだものである。The other is an example of the present invention shown in FIG. 1, in which the electrode plate 1 is wrapped so that the surface of the separator 3 without ribs 2 is in contact with the electrode plate 1.
