▎ 摘　　要

NOVELTY - The pouch film has a graphene sheet film, an adhesive layer, and a polyethylene fiber layer plated with a metal, where the metal is made of tungsten. The thickness of the graphene sheet is 40-80 micrometers. USE - Pouch film for secondary battery applied to flexible and thin-film battery using graphene material. ADVANTAGE - The film secures rigidity against external impact, secures stability against internal heat generation through excellent heat resistance, and is flexible through excellent bendability and stability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the pouch film. (Drawing includes non-English language text)
