Title:
POROUS MEMBRANE FOR SECONDARY BATTERY, SLURRY FOR SECONDARY BATTERY POROUS MEMBRANE, AND METHOD OF MANUFACTURING POROUS MEMBRANE FOR SECONDARY BATTERY, AND ELECTRODE FOR SECONDARY BATTERY, SEPARATOR FOR SECONDARY BATTERY, AND SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2014165159
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a porous membrane for secondary battery which can enhance the high temperature short circuit prevention performance sufficiently, and can enhance the cycle characteristics of a secondary battery configured by using the porous membrane for secondary battery by suppressing the dusting of the porous membrane for secondary battery furthermore.SOLUTION: A porous membrane for secondary battery contains non-conductive particles, i.e., resin particles, obtained via a step for making seed particles absorb a polymerizable monomer, by adding the seed particles to an emulsion containing the polymerizable monomer and an aqueous medium, a step for adding a water-soluble polymer having a thiol group at the end to the emulsion, and a step for polymerizing the polymerizable monomer thus absorbed, and a binder for porous membrane.
