の溶媒を加えなければならない。BACKGROUND ART Conventionally, polypropylene nonwoven fabrics have been used for separators of batteries that use non-aqueous electrolytes.
The solvent for the nonaqueous electrolyte is a mixture of ester organic solvents such as propylene carbonate (PC), ethylene carbonate, and r-butyrolactone, and ether organic solvents such as dimethoxyethane (DME), dioxolane, and tetrahydrofuran. was used. The reason why a mixture of an ester solvent and an ether solvent is used is that if an ether solvent alone is used, the electrolyte tends to evaporate easily, resulting in poor reliability during battery storage. Therefore, to solve this problem, it is necessary to add an ester solvent.

On the other hand, the negative electrode container 3 is filled with the negative electrode 4. A container containing a positive electrode and a negative electrode is coupled together through a separator 5 impregnated with an electrolytic solution, and the caulked portion is made of a gasket 6 made of polypropylene. 7 is a positive electrode current collector.

Microwaves of 13.56 KHz were applied for 3 minutes.

た。 For the nonaqueous electrolyte, 1 mol/lithium perchlorate is used as the solute, and ester propylene carbonate (PC) is used as the solvent to dissolve it.
A mixed solvent of dimethoxyethane (DME) and ether type dimethoxyethane (DME) was used. The blending ratio of propylene carbonate was varied from 100% to 30%.

約70％以上から顕著になることがわかる。 FIG. 2 shows the relationship between the internal resistance of the battery obtained as described above and the blending ratio of PC and DME in the electrolyte mixed solvent. Battery internal resistance is 10mA at 1Hz
This is the value in terms of current. Curve A is for an untreated separator and curve B is for a separator treated with plasma irradiation. The untreated separator A has a high internal resistance at any blending ratio, and the higher the blending ratio of propylene carbonate, the higher the battery internal resistance. On the other hand, separator B was subjected to plasma irradiation treatment.
It can be seen that even when the proportion of propylene carbonate increases, the internal resistance of the battery does not increase, and the result is low at all proportions. In particular, it can be seen that the effect of the plasma irradiated separator becomes remarkable when the proportion of propylene carbonate to the total amount of solvent is about 70% or more.

がることを見い出した。 Conventionally, it has been known that plasma irradiation treatment is applied to separators in batteries using alkaline aqueous solution as electrolyte . This is because it can be done. However, the fact that plasma irradiation treatment increases the lyophilicity toward ester-based organic solvents was not known.
The present invention has found that plasma irradiation treatment is effective in increasing the lyophilicity of organic solvents, especially ester-based organic solvents.
