Claims9
A pouch exterior material of a pouch-type battery capable of reducing battery swelling, the pouch exterior material comprising:
- a resin layer located inside the pouch-type battery;
- a metal layer stacked on the resin layer;
- an insulating layer stacked on the metal layer;
- and
- a pattern layer of an elastic material formed on the insulating layer,
- wherein the elastic material is at least one of natural rubber (NR), styrene-butadiene rubber (SBR), polybutadiene rubber (BR), nitrile-butadiene rubber (NBR), solution styrene butadiene rubber (SSBR), neoprene (CR), ethylene propylene rubber (EPR), ethylene propylene diene monomer (EPDM), silicone, and silicone elastomer.
A method of manufacturing a pouch exterior material, the method comprising:
- forming a resin layer, a metal layer, and an insulating layer and sequentially stacking them;
- and
- forming a pattern layer of elastic material on the insulating layer,
- wherein the elastic material is at least one of natural rubber (NR), styrene-butadiene rubber (SBR), polybutadiene rubber (BR), nitrile-butadiene rubber (NBR), solution styrene butadiene rubber (SSBR), neoprene (CR), ethylene propylene rubber (EPR), ethylene propylene diene monomer (EPDM), silicone, and silicone elastomer.
A method of manufacturing a pouch exterior material, the method comprising:
