  • Publication number: 20200168943
    Abstract: A flexible battery is disclosed. The flexible battery can include: an electrode assembly; and an exterior material in which the electrode assembly is encapsulated together with an electrolyte, in which the electrode assembly and the exterior material are formed such that patterns for contraction and extension in a longitudinal direction have the same directionality when the flexible battery is bent. As such, the patterns for contraction and extension in the longitudinal direction are formed on both of the exterior material and the electrode assembly, thereby preventing or minimizing deterioration in the physical properties even though the flexible battery is bent.

  • Patent number: 10204746
    Abstract: Provided is a super capacitor. The super capacitor, according to an exemplary embodiment of the present invention, comprises: an energy storage assembly in which a plurality of unit modules are stacked; a sealing member arranged to surround the side portion of the energy storage assembly; upper and lower plates respectively arranged on the upper and lower portions of the energy storage assembly; and a roll force compensation member, arranged between the upper and lower plates and the energy storage assembly, for preventing the center portion of the energy storage assembly from being convexly bent toward the upper and lower plates. Accordingly, overall performance can be enhanced by reducing the thickness deviation for each position, and uniform power can be generated regardless of position by resolving imbalance in impregnation.
