Separator, lithium battery including the separator, and method of preparing the separator
Abstract:
A separator for a battery having a porous base material layer and a polymer coating layer formed on at least a surface of the base material layer. The polymer coating layer includes a first fluorinated copolymer and a non-fluorinated polymer. A weight ratio of the first fluorinated copolymer to the non-fluorinated polymer is in a range of 3:1 to 1:3.
Abstract(Chinese):
