【発明の詳細な説明】 〔産業上の利用分野〕 本発明はリチウムなどのアルカリ金属を負極活物質と
し、二酸化マンガンを正極活物質とする有機電解液電池
の製造方法に関する。TECHNICAL FIELD The present invention relates to a method for producing an organic electrolyte battery using an alkali metal such as lithium as a negative electrode active material and manganese dioxide as a positive electrode active material.
リチウムなどのアルカリ金属を負極活物質とする有機電

どの有機溶媒が用いられている。このうち、特にプロピ
レンカーボネートは、誘電率が高く、電解質を高濃度に
溶解させることができ、かつ使用温度範囲が広いことか
ら、この種の電池では主溶媒として用いられることが多
い。In an organic electrolytic solution battery using an alkali metal such as lithium as a negative electrode active material, an organic solvent such as propylene carbonate, 1,2-dimethoxyethane, or 1,3-dioxolane is used as the electrolytic solution solvent. Of these, propylene carbonate is often used as a main solvent in this type of battery because it has a high dielectric constant, can dissolve an electrolyte in a high concentration, and has a wide operating temperature range.
ところで、上記電池の正極活物質として二酸化マンガン
を用いた場合、二酸化マンガンが表面に付着水、結合
水、表面官能基を有しているため表面の活性能が高く、
これが電池形成した場合に理論電位より高電位を生じる
原因となり、また電解液溶媒として前記プロピレンカー
ボネートのように環状でエステル結合を有する有機溶媒
が使用されていると、貯蔵中に二酸化マンガンとプロピ
レンカーボネートとが反応して、プロピレンカーボネー
トが酸化されて分解するため、電池内部に炭酸ガス（CO
2）が発生し、電池総高の増加や、内部インピーダンス
の増加などの電池性能の低下を引き起こすことになる。By the way, when manganese dioxide is used as the positive electrode active material of the above-mentioned battery, since manganese dioxide has attached water, bound water, and a surface functional group on the surface, the surface activity is high,
This causes a potential higher than the theoretical potential when forming a battery, and when an organic solvent having a cyclic ester bond such as the propylene carbonate is used as the electrolyte solvent, manganese dioxide and propylene carbonate are stored during storage. Reacts with each other to oxidize and decompose propylene carbonate, which causes carbon dioxide gas (CO
2 ) occurs, causing a decrease in battery performance such as an increase in total battery height and an increase in internal impedance.
そのため、これまでにも特開昭55-80276号公報に示され
るように、電池製造直後に予備放電して、プロピレンカ
ーボネートの分解を防止する方法が提案されているが、
この方法による場合、電池を１個ずつ所定電圧まで放電
させなけれならず、工業的には大変な手間を要すること
になる。Therefore, as shown in JP-A-55-80276, there has been proposed a method of preventing the decomposition of propylene carbonate by pre-discharging immediately after the production of the battery.
According to this method, it is necessary to discharge the batteries one by one to a predetermined voltage, which requires a great deal of industrial effort.
本発明は、上述したように二酸化マンガンを正極活物質
として用いた従来の有機電解液電池が貯蔵性に欠けてい
たという問題点を解決し、貯蔵性の優れた有機電解液電

する。The present invention solves the problem that the conventional organic electrolyte battery using manganese dioxide as the positive electrode active material lacks storability as described above, and the organic electrolyte battery having excellent storability is produced with good productivity.

る。The present invention, by treating manganese dioxide with a polyacid, stabilizes manganese dioxide, reduces the reactivity of manganese dioxide with propylene carbonate, and suppresses the reaction between manganese dioxide and propylene carbonate during storage, It is an object of the present invention to provide an organic electrolyte battery with little increase in total battery height and decrease in battery performance.

確ではないが、上記の処理により二酸化マンガン表面の

や結合水、表面官能基などに基づく二酸化マンガン表面
の活性が低下することによるものと考えられる。The reason why the reactivity of manganese dioxide with propylene carbonate is decreased by treating the manganese dioxide with the polyacid as described above is not always clear at present, but the treatment makes it possible to compare the active sites on the surface of the manganese dioxide. It is considered that this is because a chemically stable complex oxide is formed and the activity of the surface of manganese dioxide based on attached water, bound water, surface functional groups and the like is reduced.
