In a secondary battery case which includes an external resin layer, an internal resin layer, and an Al layer interposed between the resin layers, the present invention provides a secondary battery case where the internal internal resin layer includes a mixture of a first phase change material and a first carrier material. Moreover, the secondary battery case and an electrode assembly include an electrode lead drawn from the assembly and an insulating film coated on the electrode lead. The insulating film includes a mixture of a second phase change material and a second carrier material. Provided is a secondary battery case which can improve the cycle thereof by maintaining the internal temperature thereof at high temperature. |
