Title:
POROUS MEMBRANE
Document Type and Number:
Japanese Patent JP2017004960
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a porous membrane for a nonaqueous electrolyte secondary battery, which is less likely to curl and has improved workability.SOLUTION: The porous membrane for a nonaqueous electrolyte secondary battery contains a compound having a hydrophobic group and a nonionic hydrophilic group, an inorganic powder, and a binder resin. The compound having a hydrophobic group and a nonionic hydrophilic group is a nonionic surfactant. The inorganic powder is a metal oxide or a metal carbonate. The ratio of the inorganic powder to the total amount of the inorganic powder and the binder resin is 70 mass% or more.SELECTED DRAWING: None
