Curable composition, stretchable coating layer using the same, stretchable secondary battery, fuel cell, and stretchable transistor using stretchable coating layer, wearable device including the same, and method for manufacturing curable composition

Abstract

According to the present invention, a method for manufacturing a curable composition may include: preparing a base solution by dissolving a fluorine-based polymer in a solvent; and preparing the curable composition by providing and dissolving lithium salt, an ionic liquid, succinonitrile, an azide-based curing agent, and an additive in the base solution. A substrate (e.g., a stretchable polymer film, a carbon support, lithium foil, copper foil, a positive electrode in which a positive electrode layer is formed on a positive electrode current collector, or a negative electrode in which a negative electrode layer is formed on a negative electrode current collector) may be coated with the curable composition manufactured by the above method, and the curable composition may be cured with ultraviolet light, so that a stretchable coating layer having improved electrical and mechanical properties may be manufactured. Therefore, the stretchable coating layer may be used as a solid electrolyte layer of a stretchable secondary battery, a channel layer of a stretchable transistor, and an electrolyte layer of a fuel cell, and the stretchable secondary battery, the stretchable transistor, and the fuel cell to which the stretchable coating layer is introduced may be applied to a wearable device.
