摘要：
A separator in which at least one side of a porous substrate has thereon a coating layer containing a partially reduced graphene oxide with a sheet shape and a lithium ion conductivity polymer, which can solve the problem caused by the lithium polysulfide which occurs in the conventional lithium secondary battery, and a lithium secondary battery.
