本発明は永化した多孔質亜鉛板を陰極に用いる薄型電池
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thin battery using a permanent porous zinc plate as a cathode.
近年、電池を電源とする時計、カメラ、補聴器等の携帯
機器の発展は目ざましいものがある。In recent years, there has been a remarkable development in portable devices such as watches, cameras, and hearing aids that are powered by batteries.
これら機器の発展と共に消費電力の低減化が進み、電池
に対しても小型、薄型化が強く要求されるようになって
きた。As these devices have developed, power consumption has been reduced, and there has been a strong demand for batteries to be smaller and thinner.
従来、これら機器の電池として陰極にＡｇＯ。Conventionally, AgO was used as the cathode for batteries in these devices.
Ａｇ２Ｏ，ＨｇＯ等を陰極に汞化亜鉛を電解液にアルカ
リ溶液を用いたいわゆるアルカリ電池が多用されている
。A so-called alkaline battery is often used, which uses Ag2O, HgO, etc. as a cathode, zinc oxide, and an alkaline solution as an electrolyte.
これらアルカリ電池は安定性、容量共に優れた電池であ
るが、小型化するに伴ないその製造は困難となり、また
、電池容量等も低下する。These alkaline batteries are excellent in both stability and capacity, but as they become smaller, they become difficult to manufacture and their capacity also decreases.
本発明はこれらの欠点を除去し、生産性に優れた薄型電
池を提供することを目的とするものであり、以下、実施
例に基づいて説明する。The present invention aims to eliminate these drawbacks and provide a thin battery with excellent productivity, and will be described below based on Examples.

セパレータ、５はＡｇｅ。FIG. 1 is a cross-sectional view of the battery of the present invention, where 1 is a cathode can, 2 is a cathode made of a porous zinc plate according to the present invention, 3 is an electrolyte holding material made of cotton or the like, and 4 is made of cellophane or the like. Separator 5 is Age.
Ａ ｇ ２０ 、Ｈｇ Ｏ等を主体とする陽極合剤、６

ングである。Anode mixture mainly composed of A g 20 , Hg 2 O, etc., 6
7 is an anode can, and 7 is a plastic backing that serves as insulation and sealing.
従来、陰極２は亜鉛粉末にＣＭＣ等の糊料を添加し電解
液と共に混合したゲル状の陰極合剤、あるいは、亜鉛粉
末を圧粉成型しペレット状にしたものを用いていた。Conventionally, the cathode 2 has been made of a gel-like cathode mixture prepared by adding a glue such as CMC to zinc powder and mixed with an electrolyte solution, or a pellet formed by compacting zinc powder.
しかし、電池が薄型化されるに従い、精度良し秤量し陰
極缶に装入することが困難となってくる。However, as batteries become thinner, it becomes difficult to accurately weigh and charge them into cathode cans.
本発明の陰極は亜鉛粉末と容易に熱分解する合成樹脂粉
末を混合し、プレスあるいはロールにより圧粉し、さら
に一様の寸法となるようプレスあるいは圧延をおこなう
。The cathode of the present invention is prepared by mixing zinc powder and easily thermally decomposable synthetic resin powder, compacting the mixture using a press or roll, and further pressing or rolling to obtain a uniform size.
しかる後、添加した合成樹脂が熱分解を生じる温度以上
に加熱し焼結を行なう。Thereafter, the added synthetic resin is heated to a temperature higher than that at which thermal decomposition occurs to perform sintering.
この焼結により多孔質亜鉛板が得られるのでプレスによ
り所定の寸法に打抜き永化し、陰極として用いる。A porous zinc plate is obtained by this sintering, which is then punched out into a predetermined size using a press and used as a cathode.
従って精度の良い陰極を極めて容易に得ることが出来る
。Therefore, a highly accurate cathode can be obtained extremely easily.
次に、本発明陰極を用いた電池と従来のゲル状陰極を用
いた電池、及び、ペレット状の陰極を用いた電池をそれ
ぞれ製造しその容量を調査した。Next, a battery using the cathode of the present invention, a battery using a conventional gel cathode, and a battery using a pellet cathode were manufactured, and their capacities were investigated.
電池寸法はφ１１，６ Ｘ ３． Ｏｍｍで陽極にはＡ
ｇ２Ｏを主として用いた。Battery dimensions are φ11.6 x 3. Omm and A for the anode
g2O was mainly used.

た従来電池である。Figure 2 shows the results of discharging these batteries at a constant resistance of 7.5Ω, where a is the battery of the present invention, b is a conventional battery using pelleted zinc as the cathode, and C is a battery using gelled zinc. This is a conventional battery used for the cathode.
これらの結果から明らかなように本発明は極めて容易に
薄型電池の製造を可能とし、また、容量の大きな電池を
係ることが出来、工学的価値犬である。As is clear from these results, the present invention makes it possible to manufacture a thin battery extremely easily, and also enables a battery with a large capacity to be manufactured, and is therefore of great engineering value.
