Disclosed is a packaging for a flexible secondary battery comprising a first polymer resin layer, a barrier layer formed on the first polymer resin layer to block water and gas, and a second polymer resin layer formed on the barrier layer. The thickness of the barrier layer is 30 to 999 nm. The barrier layer is multi-layered, and comprises graphene, a dispersing agent, and pyrene as a flexible linking agent, in which there is π-π conjugation (interaction) between the graphene and the pyrene. Also disclosed is a flexible secondary battery comprising the packaging.

A method for manufacturing an anode for a cable-type secondary battery, includes forming a lithium-containing electrode layer on the outer surface of a wire-type current collector; and surrounding the outer surface of the lithium-containing electrode layer with a substrate for forming a polymer layer spirally, and pressing the outside of the substrate for forming a polymer layer to form a polymer layer on the lithium-containing electrode layer, wherein the polymer layer includes a hydrophobic polymer, an ion conductive polymer, and a binder for binding the hydrophobic polymer and the ion conductive polymer with each other. An anode obtained from the method and a cable-type secondary battery including the anode are also provided.
