Problems solved by technology

However, this method has the problem that it is difficult to control the pore size of the porous membrane
In addition, when the porous membrane produced by this method is used as a separator, there is also a problem that uneven ion transmission tends to occur inside the electricity storage device.

Embodiment

[0129] Hereinafter, the present invention will be described in more detail by citing examples, but the present invention is not limited to these examples.

[0130] 100 parts by weight of bisphenol A type epoxy resin (manufactured by Mitsubishi Chemical Corporation, jER828, epoxy equivalent 184~194g / equivalent) was dissolved in 147 parts by weight of polypropylene glycol (SANNIX PP-400 manufactured by Sanyo Chemical Industry), thereby preparing epoxy resin / polypropylene glycol solution 11. Then, this solution 11 was put into a cylindrical container 31 having an inner diameter of 120 mm×150 mm. Then, 15 parts by weight of 1,6-diaminohexane (special grade, produced by Tokyo Chemical Industry Co., Ltd.) was charged into the container 31 .

[0131] Use a vacuum device to evacuate at a pressure of 0.75 kPa through the first through hole 47b, and at the same time use a planetary agitator (manufactured by THINKY Co., Ltd., trade name "も㏏とリ弟太郎 (registered trademark)") at a revolutio...

Abstract

Provided is a container used in an agitation device, the container comprising the following: a closed bottom tubular-shaped inner cylinder (41) that is formed so that the inner circumferential surface has a cylindrical shape and that can contain therein a material (11) that includes an epoxy resin, a curing agent, and a porogen, and that is for producing an epoxy resin compound; and a tubular or columnar-shaped shaft (42) that stands upright in the center of the inner-side bottom of the inner cylinder (41). Further, provided are an agitation device that uses this container, and a manufacturing method for a separator for a non-aqueous electrolyte electricity storage device.

Description

technical field [0001] The present invention relates to a container used in a stirring device, a stirring device, and a method for manufacturing a separator for a non-aqueous electrolyte storage device. Background technique [0002] Against the background of many problems such as global environmental protection and depletion of fossil fuels, the demand for non-aqueous electrolyte power storage devices represented by lithium-ion secondary batteries and lithium-ion capacitors is increasing year by year. Conventionally, polyolefin porous films have been used as separators for non-aqueous electrolyte power storage devices. The polyolefin porous membrane can be produced by the method described below. [0003] First, a solvent and a polyolefin resin are mixed and heated to prepare a polyolefin solution. Using a mold such as a T-shaped die, the polyolefin solution is formed into a sheet, and discharging and cooling are carried out simultaneously to obtain a sheet-shaped molded bo...
