METHOD FOR FABRICATING SEPARATOR FOR NON-AQUEOUS ELECTROLYTE ELECTRICITY STORAGE DEVICE AND METHOD FOR FABRICATING NON-AQUEOUS ELECTROLYTE ELECTRICITY STORAGE DEVICE |
摘要 |
<p>The present invention provides a method for producing a separator for nonaqueous electrolyte electricity storage devices. The method allows: avoidance of use of a solvent that places a large load on the environment; and relatively easy control of parameters such as the porosity and the pore diameter. The production method of the present invention includes the steps of: preparing an epoxy resin composition containing an epoxy resin, a curing agent, and a porogen; forming a cured product of the epoxy resin composition into a sheet shape or curing a sheet-shaped formed body of the epoxy resin composition, so as to obtain an epoxy resin sheet; removing the porogen from the epoxy resin sheet by means of a halogen-free solvent so as to form a porous epoxy resin membrane; and drying the porous epoxy resin membrane by heat-roll drying.</p> |
