産業上の利用分野
本発明は易曲性を有する極板を使用した密閉形鉛蓄電池
の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in a sealed lead-acid battery using flexible electrode plates.
従来の技術
従来密閉形鉛蓄電池に使用する極仮は、鋳造格子基板あ
るいはエキスバンド格子基板にペーストを充填し、熟或
、化或の各工程を経て製造される。BACKGROUND OF THE INVENTION Conventional batteries used in sealed lead-acid batteries are manufactured by filling a cast lattice substrate or an expanded lattice substrate with paste, and then going through various processes such as ripening and chemical conversion.
？明が解決しようとする課題
従来密閉形鉛蓄電池に使用する基板は、易曲性が殆どな
く、逆にペースト充填性、作業性の面から硬化する傾向
であった。そしてこのような基板にペースト状の活物質
が連続的に充填されて極板としていたため、さらに極板
の易曲性は失なわれる。■このため極板に曲げのような
外力が加わると基板から活物質が剥離して充放電能力が
低下しさらには早期寿命となる。しかしながら、従来の
密閉形鉛蓄電池では、使用する電槽は或形電槽であるの
で、易曲性がないため、電槽に収納された極仮群に加圧
を加えることにより、活物質と極板間のガラス繊維から
なる電解液保持体の密着が保たれるようにしている。? Problems that Ming is trying to solve Conventionally, substrates used in sealed lead-acid batteries have little flexibility and, on the contrary, tend to harden in terms of paste filling properties and workability. Since such a substrate is continuously filled with a paste-like active material to form an electrode plate, the flexibility of the electrode plate is further deteriorated. ■For this reason, if an external force such as bending is applied to the electrode plate, the active material will peel off from the substrate, reducing the charging and discharging ability and shortening the lifespan. However, in conventional sealed lead-acid batteries, the container used is a shaped container, so it does not have flexibility, so by applying pressure to the polar group stored in the container, the active material and The electrolyte holder made of glass fibers is kept in close contact with the electrode plates.
ところが、近年多種多様な電池が要求されてきており、
その中でも易曲性を有する電池の場合には従来の極仮構
造では許容できない。However, in recent years, there has been a demand for a wide variety of batteries.
Among these, in the case of batteries with easy bendability, the conventional polar structure is not acceptable.
課題を解決するための手段
本発明は同極活物質が同一平面で不連続に配置され、こ
れの一部または全部を鉛又は鉛合金よりなるパンチング
メタルもしくは発泡構造としたシート状集電体でおおう
ようにした。さらにこのシート状集重体の一部又は全周
を電解液保持体で占めるようにした。Means for Solving the Problems The present invention is a sheet-like current collector in which homopolar active materials are arranged discontinuously on the same plane, and a part or all of the same is made of a punched metal or foam structure made of lead or a lead alloy. I tried to cover it. Further, a part or the entire circumference of this sheet-like aggregate was occupied by an electrolyte holder.
作用
活物質が接触している部分の集電体は、固定された状態
となる。しかし活物質が接触していない部分の集電体は
、集電体を固定する活物質がないため自由度がある。そ
してこの両者が連続することによって極板として又は電
池として易曲性をそなえる。また極板の活物質部同志の
加圧により活物質と電解液保持体の密着が保たれる。The portion of the current collector that is in contact with the working active material is in a fixed state. However, the portion of the current collector that is not in contact with the active material has a degree of freedom because there is no active material that fixes the current collector. The continuity of both provides flexibility as an electrode plate or as a battery. Further, the close contact between the active material and the electrolyte holder is maintained by pressurizing the active material portions of the electrode plates.
実施例
■は凹凸状の陽極集電体で、凹凸状を形戒する溝部には
、陽極活物質２と電解液保持体３が交互に配置され、ま
た凹凸状の陰極集電体４には、凹凸状を形戒する溝部に
陰極活物′ＪＩｔ５と電解液保持体３が交互に配置され
て、陽極集電体１と陰極集電体４間には中央部電解液保
持体６が介在している。Example (2) is an anode current collector with an uneven shape, in which the anode active material 2 and the electrolyte holder 3 are arranged alternately in the grooves forming the uneven shape, and the cathode current collector 4 with an uneven shape has anode active materials 2 and electrolyte holders 3 arranged alternately. The cathode active material 'JIt5 and the electrolyte holder 3 are arranged alternately in the groove forming the uneven shape, and the central electrolyte holder 6 is interposed between the anode current collector 1 and the cathode current collector 4. are doing.
上記のような構造にすることにより、第３図に示すよう
に極板が弯曲しても、陽極活物質２と陰極活物質５が接
触している集電部は固定されるが、陽極活物質２と陰極
活物？ｆ５が接触していない集電体部は弯曲し、これが
連続することによって、電池は易曲性を有することにな
る。With the above structure, even if the electrode plate is bent as shown in FIG. 3, the current collector where the anode active material 2 and the cathode active material 5 are in contact is fixed, but the anode Substance 2 and cathode active material? The current collector portion that is not in contact with f5 is curved, and this continuity gives the battery flexibility.
雛変
また電解液保持体部は差 形することもないため、適
当な加圧をかければ、陽極集電体１、陰極集電体４と離
れることはなく、電解液の拡散も円滑に行なわれる。Also, since the electrolyte holder does not change shape, if appropriate pressure is applied, it will not separate from the anode current collector 1 and cathode current collector 4, and the electrolyte will diffuse smoothly. It will be done.
本発明では陽極集電体ｌの活物質２と陰極集電体４の活
物質５同志の加圧により、活物質２、活物質５と電解液
保持体３の密着が保たれる。In the present invention, the active material 2 of the anode current collector 1 and the active material 5 of the cathode current collector 4 are pressurized to maintain close contact between the active material 2, the active material 5, and the electrolyte holder 3.
従って、本発明によれば電槽となるフィルムは透湿のし
ないフィルムのみでよい。これにより電槽となるフィル
ムは易曲性を保つばかりか電池の厚み、電池重量電槽原
価が減少することになる。Therefore, according to the present invention, the film serving as the battery case may be only a film that is not moisture permeable. This not only maintains the flexibility of the film that forms the battery case, but also reduces the thickness of the battery, the weight of the battery, and the cost of the battery case.
また中央部電解液保持体は、電解液保持体３に十分電解
液を保持させておけば隔離体機能をもたせるだけでよい
ため電池をさらに薄形化することが可能となる。In addition, the central electrolyte holder only needs to have a separator function as long as the electrolyte holder 3 holds sufficient electrolyte, so that the battery can be made even thinner.
さらにフィルム接触部に電解液保持体３を配置すること
によっては、外的衝撃にも強い電池となる。Furthermore, by arranging the electrolyte holder 3 at the film contact portion, the battery becomes resistant to external shocks.
さらに、平面上の集電体に活物質が不連続に存在するよ
りも、活物質の周囲にできるだけ集電体が存在する方が
さらに曲げのような外力に強くなる。Furthermore, if the current collector exists as much as possible around the active material, it will be more resistant to external forces such as bending than if the active material exists discontinuously on a flat current collector.
次に曲げ回数に対する容量試験を行った。電池は本発明
密閉形鉛蓄電池Ａと従来の密閉形鉛蓄電池Ｂ共６０Ｘ８
０Ｘ５ｍｍサイズで、一方を平面台上に固定し（固定長
さ４０ｍ＋＋＋）他方を空中とした（残り４ ０ ｍｍ
）。そして先端を上下方向に±１０ｍｍ振動させた。Next, a capacity test was performed on the number of bends. Both the sealed lead-acid battery A of the present invention and the conventional sealed lead-acid battery B are 60X8.
With a size of 0x5mm, one side was fixed on a flat table (fixed length 40m+++) and the other was placed in the air (remaining 40mm).
). The tip was then vibrated by ±10 mm in the vertical direction.
そして１０回ごとに（往復を１回）５時間率容量試験を
行った。Then, a 5-hour rate capacity test was conducted every 10 times (one round trip).
なお試験雰囲気は全て２５±１ ’Ｃと行った。The test atmosphere was 25±1'C in all cases.
第６図に試験結果を示した。これより、本発明密閉形鉛
蓄電池Ａは、回数をくり返しても容量低下しないのに対
し、従来の密閉形鉛蓄電池Ｂは急激に容量が低下する。Figure 6 shows the test results. As a result, the capacity of the sealed lead-acid battery A of the present invention does not decrease even after repeated use, whereas the capacity of the conventional sealed lead-acid battery B rapidly decreases.
このことは従来の密閉形鉛蓄電池Ｂは、振動により集電
体と活物質の密着が悪くなったものと思われる。なおＬ
は寿命判定線である。This seems to be because in the conventional sealed lead-acid battery B, the adhesion between the current collector and the active material deteriorated due to vibration. Furthermore, L
is the life judgment line.
