PURPOSE: A pouch for a secondary battery is provided to improve adhesive force of pouch by including a magentic layer, to prevent moisture penetration and leak of electrolyte, and to improve safety of a secondary battery. CONSTITUTION: A pouch for a secondary battery is a laminate in which a heat fusion layer(110), metal layer(120), outer layer(130) are lamintated, and further comprises magnetic layers(140a,140b,140c,140d). The magnetic layer is made of at least one selected from the group consisting of ferrite-based, Ni, Co, W, Fe and their alloy. The magnetic layer is installed between a hot-melting layer and a metal layer, or metal layer and external layer. |
