電極はＭｇの鋳塊よシ圧延または押出し加工を行って薄
板としていたものである。Conventionally, in batteries using Mg as the negative electrode active material, Mg
The electrode was made from an Mg ingot and rolled or extruded into a thin plate.
然しなからこれらの薄板は何れも局部的に結晶粒の大き

のまま板材に残留し、これが局部電池を形成するため極
板内で自己放電量が多くな９、これが基因して保存中に
早期劣化を生ずるものであった。However, in all of these thin plates, the size of the crystal grains differs locally or the non-uniformity of the components that occurs during casting remains in the plate material, and this causes local batteries to form inside the electrode plate. The amount of self-discharge was large9, which caused early deterioration during storage.
本発明はかかる現状に鑑み鋭意研究を行った結果、保存
性に優れ且つ小型化にして高電圧の電池を得んとするも
のである。The present invention has been made as a result of extensive research in view of the current situation, and is an object of the present invention to provide a high-voltage battery that has excellent storage stability, is compact, and has a high voltage.
本発明は電極を溶湯急冷法により得たマグネシウム又は
マグネシウム合金の箔状体にて形成したことを特徴とす

一であり、しかも急冷によるため結晶組織は超微細化を
呈する。In the present invention, magnesium is made into a uniform liquid phase, and the foil-like body is obtained by rapidly cooling and solidifying the magnesium in the liquid phase, so that the composition is uniform, and the crystal structure becomes ultra-fine due to the rapid cooling.
従ってこの箔状体にて極板を形成した場合局部電池をお
こすことはほとんどなく、極板内の自己放電もおさえる
ことが出来るため、電池としての保存性を著しく向上す
ることが出来る。Therefore, when the electrode plate is formed from this foil-like material, local battery is hardly generated and self-discharge within the electrode plate can be suppressed, so that the storage life of the battery can be significantly improved.

ことができる。Furthermore, since the electrode according to the present invention is made of a foil-like material with a thickness of 100 microns or less and usually about 60 microns, it can be made thinner than conventional magnesium foil produced by rolling, etc., so that a compact cell can be constructed. In the case of the same volume, high voltage batteries can be used by incorporating many single cells.

明らかに結晶粒が微細になっていることが判明した。The thus obtained electrode plates for batteries of the present invention and electrode plates for comparative examples were measured using a microscope in order to detect their crystal structures. It was found that the crystal grains in FIG. 1A were clearly finer than those in FIG. 1B.
