摘要:
A composite separator, a method of preparing the composite separator, and a secondary battery including the composite separator are provided. The composite separator includes a heat-resistant nonwoven fabric, and a porous coating film on at least one surface of the heat-resistant nonwoven fabric and including a multi-phase polymer including a stationary phase segment and a reversible phase segment, wherein an amount of the stationary phase segment is larger than an amount of the reversible phase segment.
