Title:
分離膜及びこれを含むリチウム二次電池
Document Type and Number:
Japanese Patent JP6937901
Kind Code:
B2
Abstract:
The present invention relates to a separator in which at least one side of the porous substrate is coated with 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.
