摘要： A graphite composition is provided. A graphite composition according to one embodiment of the present invention comprises: a graphite composite in which nanoparticles having a catecholamine layer on the surface thereof are fixed on graphite; and graphite of at least one of graphite flakes, spherical graphite, and expanded graphite. According to this, since the graphite composition has a high dispersibility in a substrate of a different material, a composite material thus realized exhibits a uniform heat dissipation performance and can prevent mechanical strength from deteriorating at a specific position. In addition, since the compatibility with the substrate of a different material is excellent and thus the interface property with the substrate is excellent, the realized composite material can exhibit a further improved heat dissipation performance and mechanical strength. Furthermore, it is very easy to form shapes during injection/extrusion molding in combination with a substrate, and molding into complicated shapes is also possible.

摘要： A manufacturing method for a flexible battery including injecting an electrolyte into an opening of an exterior material accommodating an electrode assembly contained therein and impregnating the electrode assembly with the electrolyte through a pressure difference inside the exterior material; and a sealing step of sealing the opening. Because the electrode assembly provided in the battery can be completely impregnated with an electrolyte, no spot occurs on the surface of a negative electrode filled with the electrolyte. In addition, the flexible battery can prevent or minimize deterioration of physical characteristics that the battery is required to exhibit, even if repeated bending occurs.
