COMPOSITE SUBSTRATE, SECONDARY BATTERY ELECTRODE INCLUDING SAME, AND ELECTRODE FABRICATION METHOD USING SAME

Abstract

A composite substrate includes a polymer layer extending in a first direction, and a first metal layer and a second metal layer on opposite sides of the polymer layer, respectively, the opposite sides of the polymer layer being spaced apart from each other in a second direction that is a thickness direction of the polymer layer, wherein each of the first metal layer and the second metal layer protrudes farther than an end of the polymer layer, and wherein a first protrusion protruding from the first metal layer and a second protrusion protruding from the second metal layer are joined to each other.
