特性等にも優秀な電極である。しかし、最近はこの電池
に対しても高エネルギー密度化の要望が強く。Conventional technology The system that currently represents sealed alkaline storage batteries is a cylindrical sealed nickel-cadmium storage battery that uses nickel oxide as the positive electrode active material and cadmium as the negative electrode active material, and is commonly known as a two-cadmium battery. . Usually, - the positive electrode used in this battery is a sintered positive electrode, which is made by impregnating and filling the inside of a sintered nickel base with nickel salt and converting it into an active material, which has excellent mechanical strength. It is also an excellent electrode in terms of charge and discharge characteristics. However, recently there has been a strong demand for higher energy density for these batteries.

持体との接触力が低下し、前記と同様に充放電特性の劣
化をきたす点である。Regarding the positive electrode, a non-sintered electrode that uses a perforated plate, screen, or sponge-like porous nickel material with a small amount of metal in place of the above-mentioned substrate, and is coated or filled with nickel oxide powder at a high density. It is being considered. Here, an electrode with a perforated plate or screen as a support and active material powder coated on both sides is a coated electrode, and an electrode with a sponge-like porous nickel material as a support and active material powder filled in it. will be referred to as a foamed metal electrode. Among these, some foamed metal electrodes have begun to be put into practical use, but these non-sintered electrodes still have the following common problems compared to sintered electrodes. In other words, the mechanical strength of the electrode is poor due to the small amount of metal used in the support.
When processing spiral electrodes, many cracks occur, which deteriorates the charge and discharge characteristics, and as a result of the electrode expanding due to repeated charging and discharging, the bond between the active material powder and the support that also serves as a current collector deteriorates. This is the point where the contact force decreases and the charge/discharge characteristics deteriorate as described above.
発泡メタル式電極においては、支持体が三次元骨格を有
していて焼結基板に近く、塗着式電極と比べて前記課題
を大きく改善したがまだ充分とはいえない。In foamed metal electrodes, the support has a three-dimensional skeleton and is similar to a sintered substrate, and although this problem has been greatly improved compared to painted electrodes, it is still not sufficient.
そこで、従来からこれらの課題解決のために以下の提案
がなされてきた。Therefore, the following proposals have been made to solve these problems.
（１）塗着式の場合、導電性粉末とともに結着性に優れ
る樹脂粉末や樹脂製繊維を活物質中に混在させて活物質
粉末どおしの電子伝導度を高め、同時に結合力を向上さ
せる。(1) In the case of the coating type, resin powder or resin fibers with excellent binding properties are mixed with the conductive powder in the active material to increase the electronic conductivity between the active material powders and improve the bonding strength at the same time. let
（２） （１）をさらに進めて、樹脂繊維の代りに導
電性の金属やカーボンより成る繊維を用いる。(2) Taking (1) further, fibers made of conductive metal or carbon are used instead of resin fibers.
（３）塗着式の場合、電極表面を導電性粉末あるいは金
属をメッキして電極を導電剤で被覆する。(3) In the case of the paint type, the electrode surface is plated with conductive powder or metal, and the electrode is coated with a conductive agent.
（４）発泡メタル式の場合、支持体であるスポンジ状ニ
ッケル多孔体中に、あらかじめ金属製のワイヤーまたは
リボンを厚さ方向と直角方向に入れ、渦巻き状の加工時
に生ずる亀裂を抑制する。(4) In the case of the foam metal type, a metal wire or ribbon is placed in advance in a direction perpendicular to the thickness direction into the sponge-like nickel porous material that is the support to suppress cracks that occur during spiral processing.
発明が解決しようとする問題点
上記（１） 、 （２）の方法は、塗着式電極としては
機械的強度および電子伝導度を改善するが、結着剤の結
着力はまだ充分といえず、とくに充放電の繰返しで生じ

触劣化が大きくなり支持体から隔る部分、つまり電極表
面付近の活物質が作用しにくくなる。ここで、結着剤の
量を増加させると結着剤により充放電反応に支障をきた
す。Problems to be Solved by the Invention Although the methods (1) and (2) above improve the mechanical strength and electronic conductivity of a coated electrode, the binding force of the binder is still insufficient. In particular, when the electrode expands due to repeated charging and discharging, contact with the support (in this case, a plate) deteriorates significantly, and the active material near the electrode surface, which is separated from the support, becomes less effective. . Here, if the amount of the binder is increased, the binder will interfere with the charge/discharge reaction.
（３）の方法は、製法が複雑化するとともに電極にに大
きな亀裂が発生した時には亀裂部の両側は電気的に絶縁
され、充放電特性を充分改善させるに至らない。In method (3), the manufacturing method becomes complicated, and when a large crack occurs in the electrode, both sides of the crack are electrically insulated, and the charge/discharge characteristics cannot be sufficiently improved.
（４）の方法は、改善方法としては優れているが、通常
の薄い支持体内部に長いワイヤーやリボンを挿入する操
作が複雑である。Method (4) is an excellent improvement method, but the operation of inserting a long wire or ribbon into the inside of a normal thin support is complicated.
本発明は、上記した従来の問題点を解消し、非焼結式正
極を用いた円筒密閉形アルカリ蓄電池における充放電特
性を改良し、製法も容易な蓄電池を提供することを目的
とする。It is an object of the present invention to solve the above-mentioned conventional problems, improve the charging and discharging characteristics of a cylindrical sealed alkaline storage battery using a non-sintered positive electrode, and provide a storage battery that is easy to manufacture.

のである。Means for Solving the Problem In order to solve this problem, the present invention provides an electrode group in which a non-sintered positive electrode and a negative electrode are processed into a spiral shape with a separator interposed therebetween, in which a conductive material is added to the non-sintered positive electrode side of the separator. It has been given a gender.

なる。Function: According to this structure, even if a crack occurs in the electrode when the electrode is processed into a spiral shape, both sides of the crack can be electrically connected, and even if the electrode expands due to repeated charging and discharging, the electrode surface remains active. If the contact between the substance and the support is not degraded even in part, the charge/discharge characteristics will be improved as a result of promoting electrical contact between the active material and the support over the entire electrode surface.
