Reinforced pouch type secondary battery

A pouch type secondary battery comprising:

• an electrode assembly comprising positive and negative electrodes with a separator interposed therebetween, and positive and negative terminal portions extending from the positive and negative electrodes, respectively;
• a first reinforcement member comprising a first surface and a second surface opposite the first surface, the first surface adhered to at least one of an upper face and a bottom face of the electrode assembly;
• and
• a pouch casing in which the electrode assembly is housed, wherein the positive and negative terminal portions extend outward from the pouch casing, the positive and negative terminal portions being insulated from each other at a sealed portion of the pouch casing,
• wherein the pouch casing comprises a first resin material layer, a second resin material layer, and a metallic material disposed between the first resin material layer and the second resin material layer,
• wherein an entire first surface of the first reinforcement member contacts the electrode assembly, and
• wherein the first reinforcement member is not adhered to a side of the electrode assembly facing the sealed portion of the pouch casing.
