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 resistance-switchable material containing: an insulating support; and a complementary resistance switchable filler dispersed in the insulating support, wherein the complementary resistance switchable filler has a spherical core-shell structure containing: a spherical conductive core containing a conductive material; and an insulating shell formed on the surface of the core and containing an insulating material. The resistance-switchable material is capable of exhibiting complementary resistive switching characteristics with improved reliability and stability as symmetrical uniform filament current paths are formed in respective resistive layers adjacent to two electrodes with the conductive core of the complementary resistance-switchable filler at the center due to the electric field control effect by the spherical complementary resistance-switchable filler
