本考案は鉛蓄電池の改良に関し、陰陽極板の底
部における短絡を防止して電池の長寿命化を達成
することを目的とする。[Detailed Description of the Invention] The present invention relates to the improvement of lead-acid batteries, and aims to extend the life of the battery by preventing short circuits at the bottoms of the cathode and anode plates.
鉛蓄電池の寿命を決定する因子に底部短絡があ
り、寿命後の電池を調べてみると、そのほとんど
が陰陽極板の底部において脱落した活物質による
短絡を起こしている。従来、前記短絡を防止する
技術としては、
(1) 電槽底部に鞍を設け該鞍に極板群を載置し
て、脱落した陽極活物質を鞍より下に落すも
の。 A short circuit at the bottom is a factor that determines the lifespan of lead-acid batteries, and when examining batteries after their lifespan, most of them are found to have short circuits due to active material falling off at the bottoms of the anode and cathode plates. Conventional techniques for preventing short circuits include: (1) A saddle is provided at the bottom of the battery case, a group of electrode plates is placed on the saddle, and the anode active material that falls off falls below the saddle.
(2) 陰陽いずれかの極板を袋状セパレータで被覆
し脱落した陽極活物質と陰極板の接触を防止す
るか、陽極活物質の脱落自体を防止するもの。(2) Either the positive or negative electrode plate is covered with a bag-like separator to prevent contact between the anode active material that has fallen off and the cathode plate, or to prevent the anode active material from falling off at all.
がある。There is.
上記１の鉛蓄電池の場合、寿命中期の状態は第
１図、第２図の如くである。 In the case of the above-mentioned lead-acid battery 1, the state in the middle of its life is as shown in FIGS. 1 and 2.
脱落した陽極活物質１は、鞍２の下に堆積して
いるが、第２図に示すように一部は鞍２の上にも
堆積し、鞍２に沿つてガラスマツト３およびセパ
レータ４の下部を通過し陰極５と接触しており完
全には底部短絡を防止できない。６は陽極板、７
は電槽、８，８′はストラツプである。また、上
記２の場合、極板底部における短絡は完全に防止
できるが、電極の組立工程が複雑で生産性は従来
の1/100程度に落ち、セパレータのコストも高い
ので総合的なコストは従来の３倍程度になる問題
点がある。 The fallen anode active material 1 is deposited under the saddle 2, but some of it is also deposited on the saddle 2, as shown in FIG. It passes through and comes into contact with the cathode 5, so it is not possible to completely prevent a bottom short circuit. 6 is the anode plate, 7
is a battery case, and 8 and 8' are straps. In addition, in case 2 above, short circuits at the bottom of the electrode plate can be completely prevented, but the electrode assembly process is complicated and the productivity is about 1/100 of the conventional one, and the cost of the separator is high, so the overall cost is lower than the conventional one. There is a problem that it is about three times as large.
本考案は上記の問題点を解決するため、極板群
を懸垂加圧状態で電槽に収納したものであり、そ
の手段は第３図に示す通りである。 In order to solve the above-mentioned problems, the present invention stores a group of electrode plates in a battery case in a suspended and pressurized state, and the means for doing so is as shown in FIG.
すなわち、陰陽極板、ガラスマツト、セパレー
タを組合せた極板群９の両面に耐酸性の平板１
０，１０′を配置し、該平板１０，１０′の上縁に
極板群９のストラツプ８，８′を載置している。 That is, an acid-resistant flat plate 1 is placed on both sides of an electrode plate group 9 that combines cathode and anode plates, glass mats, and separators.
0 and 10' are arranged, and the straps 8 and 8' of the electrode plate group 9 are placed on the upper edges of the flat plates 10 and 10'.
極板群９はこの懸垂状態で電槽に収納され電槽
底部との間に空間を有すると共に平板１０，１
０′の外側になる面に設けたリブ１１が電槽内壁
を押圧することによつて、群加圧が大きくかけら
れる。 The electrode plate group 9 is stored in the battery case in this suspended state, with a space between it and the bottom of the battery case, and flat plates 10 and 1.
A large group pressure is applied by the ribs 11 provided on the outer surface of 0' pressing against the inner wall of the battery case.
極板群９を平板１０，１０′に懸垂するために
は、ストラツプ８，８′の寸法は極板群９の総厚
みより大きいことが必要であり、同一である方が
よい。 In order to suspend the plate group 9 from the flat plates 10, 10', the dimensions of the straps 8, 8' must be larger than the total thickness of the plate group 9, and preferably the same.
本考案の蓄電池の寿命中期の状態は第４図に示
す通りであり、脱落した陽極活物質１は大部分が
電槽７の底部に落下し、一部はガラスマツト中に
残存しているが、陰極板と底部短絡は生じていな
い。また、第５図に本考案電池と従来電池（鞍上
に極板群を載置した電池）のJIS寿命試験５時間
率容量の変化を示した。第５図から明らかなよう
に、充放電150サイクル前から本考案の効果が現
われ、寿命は従来の２倍程度に延びた。 The condition of the storage battery of the present invention in the middle of its life is as shown in FIG. 4. Most of the fallen anode active material 1 falls to the bottom of the battery case 7, and some remains in the glass mat. No short circuit occurred between the cathode plate and the bottom. In addition, FIG. 5 shows the change in the 5-hour rate capacity of the JIS life test of the battery of the present invention and the conventional battery (a battery with a group of electrode plates placed on the saddle). As is clear from FIG. 5, the effects of the present invention became apparent before 150 charge/discharge cycles, and the life span was approximately twice that of the conventional one.
上述のように、本考案は極板の底部における短
絡を防止し且つ群加圧を十分にかけたので電池寿
命が大きく延び、使用する電槽の形状は従来のも
のと何ら変わるところがなく、鞍を必要としない
分だけ原材料も少なくできる上に極板群加圧力の
調整も容易で電池組立てが容易である点極めて実
用的である。 As mentioned above, the present invention prevents short circuits at the bottom of the electrode plates and applies sufficient group pressure, greatly extending battery life.The shape of the battery case used is no different from the conventional one, and the saddle It is extremely practical in that the amount of raw materials that are not needed can be reduced by the amount that is not needed, and the pressure force applied to the electrode plate group can be easily adjusted, making it easy to assemble the battery.
