    摘要： A battery case for enclosing and hermetically sealing a battery body which generates current. The case includes a first polyethylene terephthalate layer, which is an innermost layer with respect to a battery body, which is adhered to another part of the same layer when sealing the battery body, a polymer layer on the first polyethylene terephthalate layer, a second polyethylene terephthalate layer on the polymer layer, and a polypropylene layer, which is an outermost layer with respect to the battery body, on the second polyethylene terephthalate layer. Therefore, short circuits generated during adhesion between edges of upper and lower portions of the case can be prevented, improving the case sealing process. Also, the deterioration of battery performance, due to a micro short circuit occurring during the sealing of the case, can be avoided. Further, the case sealing process can be safely performed, irrespective of conditions of thermal fusion such as temperature, pressure, and time.
