METHOD FOR MANUFACTURING SEPARATOR FOR NON-AQUEOUS ELECTROLYTE ACCUMULATOR AND METHOD FOR MANUFACTURING NON-AQUEOUS ELECTROLYTE ACCUMULATOR |
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 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 subjecting at least one surface of the porous epoxy resin membrane to atmospheric-pressure plasma treatment so as to remove a surface portion of the porous epoxy resin membrane.</p> |
