The present invention provides a packaging material for batteries, which has excellent moldability, even after heat-melting sealant layers to seal battery elements, and then long-term durability tests under high temperature and high humidity. There is no decrease in bonding strength between layers, and no appearance defects such as bumps between layers.nThe present invention relates to a two-component adhesive, a battery packaging material, a battery container, and a battery using the adhesive. The two-component adhesive includes a polyol composition (A) and a polyisocyanate composition ( B), and the polyisocyanate composition (B) includes: an isocyanate compound (B1) containing an aromatic polyisocyanate, and selected from the group consisting of diphenylmethane diisocyanate and carbodiimide modified diphenylmethane diisocyanate At least one isocyanate compound (B2). |
