含まない関係上、本質的にはセパレータの必要はない
が、電池特性の向上を図るため、完全な固体の電解質で
はなく、ゲル状の電解質を用いている。In the polymer electrolyte battery, since the electrodes and the polymer electrolyte layer essentially do not contain a free liquid, there is essentially no need for a separator, but the battery characteristics are improved. Therefore, a gel electrolyte is used instead of a completely solid electrolyte.

ぜい５０〜８０％であって、それ以上に空孔率の大きな
ものは得られないため、ポリマー電解質層の厚さが厚く
なり、負荷特性を低下させる原因になっていた。Since the gel electrolyte is softer and has a lower physical strength than the solid electrolyte, if an attempt is made to separate the electrodes only by the gel electrolyte, the electrolyte layer is broken when pressed or bent. There was a risk of short circuit. For this reason, it is common practice to use a nonwoven fabric as a support for the polymer electrolyte layer. However, it is difficult to produce a uniform and thin organic fiber nonwoven fabric due to its manufacturing method. Is difficult to obtain industrially. Further, the porosity is at most 50 to 80%, and a porosity larger than that cannot be obtained, so that the thickness of the polymer electrolyte layer is increased, which causes a decrease in load characteristics. .

An object is to provide an electrolyte battery.

ことにより、上記課題を解決したものである。According to the present invention, a support for a polymer electrolyte layer has a fiber diameter of 1 μm or less and a porosity of 8%.
The above problem has been solved by using a 0 to 95% glass fiber nonwoven fabric and forming a polymer electrolyte in the pores to form a polymer electrolyte layer.

たポリマー電解質電池が得られるようになる。That is, since the glass fiber nonwoven fabric has high strength of the fiber itself, the porosity can be increased, and high strength can be ensured even if the thickness is reduced, and the thin glass fiber nonwoven fabric having a large porosity. By using as a support, the electric resistance of the polymer electrolyte layer can be reduced without causing a short circuit, whereby a polymer electrolyte battery having excellent load characteristics can be obtained.

The glass fiber is obtained by using an acrylic binder or an acrylic-melamine binder to make paper from an aqueous liquid and drying.

で、ガラス繊維としては１μｍ以下であって０．１μｍ
程度までのものを使用することが好ましい。The fiber diameter must be 1 μm or less in order to obtain a nonwoven fabric having a large porosity and a small thickness.
The thinner is more convenient for the above purpose, but if it is too thin, it is theoretically possible to produce it, but it becomes industrially expensive and cannot be used substantially as a nonwoven fabric material. 0.1 μm below
It is preferred to use up to a degree.

このガラス繊維不織布の空孔率としては８５〜９５％が
より好ましい。なお、この空孔率は特に明示がない限り
体積％である。The porosity of the glass fiber nonwoven fabric is 80 to 95%
However, when the porosity is lower than 80%, the fiber portion is increased, the conduction path of ions is obstructed, the resistance is increased, and when the porosity is higher than 95%, It becomes difficult to maintain the strength as a nonwoven fabric,
This is because a short circuit is likely to occur. And
The porosity of this glass fiber nonwoven fabric is more preferably 85 to 95%. The porosity is% by volume unless otherwise specified.

00 µm, particularly preferably 50 to 70 µm. By setting the thickness of the glass fiber non-woven fabric to 40 μm or more, the polymer electrolyte layer can have a suitable strength to prevent the occurrence of a short circuit, and the thickness of the glass fiber non-woven fabric to 100 μm or less. Thereby, the load characteristics and the energy density can be kept in good ranges.

に少なく、実質的に悪影響はない。It is said that when glass fibers are used in a lithium-based battery, the glass dissolves due to the reaction between the lithium metal and the glass. However, when the electrolyte is made into a gel polymer electrolyte, the generation of dendrite by the electrode reaction occurs. Is suppressed, so that the use of a glass fiber nonwoven fabric does not have a substantial adverse effect. Further, since the gel-like polymer electrolyte layer is formed on the surface of the glass fiber, even if the dendrite is generated, there is very little direct contact with the glass fiber, and there is substantially no adverse effect.
