The materials of the first structural material 32 and the second structural material 34 can be metal materials (such as steel), ceramic materials, fibers, glass, high Molecular materials (such as polymer elastomers) or other suitable materials, for example, the first structure material 32 and the second structure material 34 can be similar to a hinge structure; the buffer material 33 is sandwiched between the first structure material 32 and the peripheral edge of the second structural material 34, because the structure and setting position of the buffer material 33 can resist the binding force F from the flexible body 20, so the first structural material 32 and the second structural material 34 can be supported, so that the first structural material 32 and the second structural material 34 can be supported in the first structure. A storage space 12 is formed between the material 32, the second structural material 34 and the buffer material 33 to accommodate the flexible battery cell 10, wherein the storage space 12 can accommodate a flexible battery cell 10, or a plurality of flexible battery cells 10, and multiple flexible battery cells 10 can be connected in parallel or in series. In more detail, the buffer material 33 has a top and a bottom, which are respectively connected to the first structural material 32 and the second structural material 34.

Please refer to FIG. 1 and FIG. 2 at the same time. FIG. 2 is a schematic diagram of the flexure of the flexible outer package of the present invention. The first structural material 32, the second structural material 34 and the buffer material 33 resist the binding force F of the flexible body 20 and form a placement Space 12, of course, the cushioning material 33 sandwiched between the first structural material 32 and the second structural material 34 must be configured so that the first structural material 32 and the second structural material 34 can have a curved state, so as to avoid the first structural material 32 or the deflection of the second structural material 34 is completely restricted; when a flexural force F' is applied to the flexible body 20, the flexible body 20 changes from the initial state to the bent state, while the first structural material 32, the second structural material 34. The buffer material 33 and the flexible battery core 10 are flexed and deformed with the flexible body 20. The deformation of the buffer material 33 may include stretching deformation or bending deformation, and provide a maximum amount of deformation during the flexing process. Therefore, the first structure The material 32, the second structure material 34 and the cushioning material 33 not only form the placement space 12, but also provide protection for the flexible battery cell 10 against puncture and excessive deflection. More specifically, when the flexible body 20 changes from the initial state to bending state or from the bending state to the initial process, the stress caused by the deflection can be divided into a positive component force perpendicular to the surface of the flexible battery core 10 and a lateral component force parallel to the surface of the flexible battery core. The lateral force and lateral force may be generated from the friction between the surfaces of the flexible battery core 10 and increase the probability of damage to the flexible battery core 10. Furthermore, the frictional force on the surface of the flexible battery core 10 may cause deflection resistance and surface damage. Therefore, the deformation of the first structural material 32, the second structural material 34 and the buffer material 33 can be used to carry and share the force acting on the flexible battery core 10 and the internal layers of the flexible battery core 10 or the flexible battery core.
