WIPO Patent Application WO/2020/080918
Kind Code:
A1
Abstract:
The present invention is to improve the moisture barrier performance and flexibility of flexible secondary batteries, and provides a packaging for a flexible secondary battery and a flexible secondary battery comprising same. The packaging for a flexible secondary battery has a tubular form surrounding the outer surface of an electrode assembly, and comprises: a mechanical support layer; a reduced graphene oxide (rGO) layer disposed on the upper surface of the mechanical support layer and comprising a plurality of reduced graphene oxide sheets; a heat-shrink layer disposed on the upper surface of the reduced graphene oxide layer; and a sealant layer disposed on the upper surface of the heat-shrink layer, wherein the plurality of reduced graphene oxide sheets in the reduced graphene oxide layer have electrostatic interactions formed between the reduced graphene oxide sheets adjacent to each other.
