FLEXIBLE BATTERY, MANUFACTURING METHOD THEREFOR, AND AUXILIARY BATTERY COMPRISING FLEXIBLE BATTERY

摘要

A flexible battery is provided. A flexible battery according to one embodiment of the present invention comprises: an electrode assembly; and an exterior material for sealing the electrode assembly along with an electrolyte. Both the electrode assembly and the exterior material are formed such that patterns for contraction and relaxation with respect to the longitudinal direction have the same directionality in the event of being bent. As such, the patterns for contraction and relaxation with respect to the longitudinal direction are formed on both the exterior material and the electrode assembly, thereby preventing or minimizing deterioration of the required physical property even if bending occurs.
