A flexible battery is provided. According to an embodiment of the present invention, the flexible battery comprises: an electrode assembly; and a cladding encapsulating the electrode assembly with an electrolyte, and having an insulating layer, provided in one surface exposed to the outside, for blocking a heat movement between the inside and the outside of the battery. The electrode assembly and the cladding individually have a pattern for contraction and relaxation in a lengthwise direction when bending, which is formed to have the same directivity. Accordingly, the flexible battery has excellent heat movement blocking between the inside and the outside of the flexible battery, and excellent durability while having excellent flexibility, thereby being applied to various electronic devices requiring a flexible battery such as a wearable device of a smart watch, a watch strap, etc., as well as a rollable display or the like. |
