本発明はフィルム状の超薄形電池に用いる電１Ｍ／［解
質複合体の製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for producing a 1M electrolyte composite for use in film-like ultra-thin batteries.
従来技術とその問題点
リチウムまたは、リチウム合金を負極とするフィルム状
の超薄形電池の提案が多くなされている。Prior Art and Its Problems Many proposals have been made for film-shaped ultra-thin batteries using lithium or lithium alloy as a negative electrode.
しかし、リチウムンートは均一な厚みを容易に得ること
が困難であった。However, it has been difficult to easily obtain a uniform thickness for lithium cement.
従来、ノズルから押出してシートとする方法が採用され
ていたが、この方法ではシートの厚さは０．０７〜０．
１ｕが限界であった。これ以下では厚さが不均一となる
。Conventionally, a method of extruding sheets from a nozzle has been adopted, but with this method, the thickness of the sheet is 0.07 to 0.
The limit was 1u. Below this, the thickness becomes non-uniform.
又、ロー〃圧延により薄膜化する方法もあるが、リチウ
ムがローμに付着し、生産性が悪いという欠点があった
。There is also a method of thinning the film by low rolling, but this has the disadvantage that lithium adheres to the low μ and productivity is poor.

に重要である。In addition, as the ion conductive material used in thin batteries, solid electrolytes, especially solid polymer electrolytes, are advantageous because they are easy to manufacture, do not leak, and can be manufactured into 7μ shapes of any shape. It is seen as promising. However, when using a solid electrolyte, it is necessary to take measures to maintain good contact between the electrode and the electrolyte. Furthermore, among thin batteries, the issue of contact is extremely important in batteries that are particularly flexible, since it is not possible to apply pressure from the outside or inside of the electrodes, unlike rolled-up cylindrical batteries.
