Document Type and Number:
Japanese Patent JP7166773
Kind Code:
B2
Abstract:
To provide a power storage device separator excellent in adhesiveness with an electrode and heat resistance and also excellent in ion permeability.SOLUTION: A power storage device separator includes: a base material; an inorganic filler porous layer formed on at least one face of the base material; and a thermoplastic polymer-containing layer formed on at least a part of a surface of the inorganic filler porous layer. The inorganic filler porous layer includes inorganic fillers and has a plurality of pores. The thermoplastic polymer-containing layer contains a thermoplastic polymer. The thermoplastic polymer includes a particulate polymer, the average particle size of the particulate polymer being larger than the average pore size of the inorganic filler porous layer.SELECTED DRAWING: None
