Abstract
A packaging for a flexible secondary battery improves the vapor barrier performance and flexibility of the flexible secondary battery. The packaging is in a shape of a tube that is wrapped around an outer surface of an electrode assembly, and includes a mechanical support layer; a reduced graphene oxide layer disposed on the mechanical support layer and including a plurality of reduced graphene oxide sheets; a heat shrink layer disposed on the reduced graphene oxide layer; and a sealant layer disposed on the heat shrink layer, wherein the plurality of reduced graphene oxide sheets in the reduced graphene oxide layer forms electrostatic interaction between adjacent sheets of the plurality of reduced graphene oxide sheets. A flexible secondary battery including the packaging is also provided.
