Title:
SEPARATOR FOR NON-AQUEOUS ELECTROLYTE ACCUMULATORS, NON-AQUEOUS ELECTROLYTE ACCUMULATOR AND MANUFACTURING METHODS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/172787
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a separator for non-aqueous electrolyte accumulators, such that the obtained separator is relatively strong, and said method renders possible the control of the porosity, the pore size, and other parameters, with relative ease whilst avoiding the use of solvents that have a significant impact on the environment. The present invention relates to a method for manufacturing a separator for non-aqueous electrolyte accumulators which has a thickness in the range of 5-50μm. The method according to the present invention includes: a step for preparing an epoxy resin composition including a glycidyl amine type epoxy resin, a hardener, and a porogen; a step for forming a hardened body of the epoxy resin composition into a sheet or hardening a sheet compact of the epoxy resin composition, in order to obtain an epoxy resin sheet; and a step for removing the porogen from the epoxy resin sheet using a halogen-free solvent.
