は、最近のコードレス式のポータブル機器の普及
により、その需要が益々増加している。Conventional technology and its problems So-called maintenance-free lead-acid batteries, which use a positive electrode grid made of a lead alloy that does not contain antimony, such as a Pb-Ca-Sn alloy, are the latest cordless portable batteries. The demand for such devices is increasing as the devices become more widespread.
ところでこの種の正極格子体は電池を使用する
に従つて延びると云う性質があり、特に耳とは反
対の側の上方には、緊圧力等の伸びを防止する力
が働かず、よつてこれが負極ストラツプの下面に
接触して短絡を起こし、寿命となると云う欠点が
あつた。 By the way, this type of positive electrode lattice has the property of elongating as the battery is used, and there is no force to prevent it from elongating, such as tightening force, especially above the side opposite to the ear, so this It had the disadvantage that it came in contact with the bottom surface of the negative electrode strap, causing a short circuit and shortening its life.
この伸びは高さ及び幅方向において４〜８％程
度であるが、これは正極格子体に充放電に伴い形
成された腐食層の応力に起因するものである。そ
してこの現象自体をなくする工夫は今のところな
い。 This elongation is about 4 to 8% in the height and width directions, and this is due to the stress of the corrosion layer formed on the positive electrode grid during charging and discharging. There is currently no way to eliminate this phenomenon itself.

を吸収するかしているが、これらの方法では、そ
の組立が煩雑となつたり、電池の容積を増大させ
ると云う欠点があり、ひいては電池の電気特性を
低下させていた。 Therefore, conventional structures for suspending the positive electrode plate leave room for the positive electrode plate to stretch at the bottom of the battery case, or the ears of the positive electrode plate are lengthened to absorb the stretching of the back plate. However, these methods have the drawbacks of complicating the assembly and increasing the volume of the battery, which in turn reduces the electrical characteristics of the battery.
