Abstract: The present disclosure relates to a stretchable electrode, a method for preparing the same and a stretchable battery including the stretchable electrode. The stretchable electrode of the present disclosure, which is prepared by crosslinking a hydroxyl-functionalized fluorine-based polymer binder physically using a ketone-based solvent or chemically with a crosslinking agent, has superior stretchability, has improved interfacial adhesivity to an active material through Fenton's oxidation, exhibits improved stability under various mechanical deformations of the electrode such as stretching, etc. and can uniformly maintain the electrical conductivity, battery capacity and charge-discharge performance of the electrode.
In addition, the stretchable battery of the present disclosure, which includes the stretchable electrode, a stretchable current collector, a stretchable separator and a stretchable encapsulant, has improved stretchability and superior battery stability under various deformations due to high degree of freedom of structures and materials. In addition, the stretchable battery of the present disclosure can be prepared as a fiber battery by printing an electrode and a current collector sequentially on both sides of a stretchable fabric, which can be worn, e.g., around sleeves due to superior stretchability and high structural degree of freedom and retains high battery performance and mechanical stability even under mechanical deformation. Therefore, it can be applied to a mobile display for a health monitoring system or a smartwatch.-

Abstract: A conductive polymer composite for adhesion to a flexible substrate contains a polymer adhesive containing a curable polymer and a curing agent; and a conductive filler containing a metal and a carbonaceous material dispersed in the polymer adhesive. The conductive polymer composite is suitable for application to not only the human body but also other objects having irregular surface. In addition, due to enhanced adhesive strength of the conductive polymer composite to the flexible substrate, the reduction in conductivity or conductivity breakdown caused by external stress can be prevented and flexibility and stretchability can be improved.
