Abstract
Proposed is a current collector for a positive electrode that substitutes for metal foil and includes a polymer film made of a nonmetal, nonconductor material, and an aluminum conductive material configured to define an outermost surface of the current collector for a positive electrode by being formed or applied, with a thickness of 0.25 to 0.6 μm, onto at least one of upper and lower surfaces of the polymer film, in which the conductive material serves as an electrochemical fuse or performs a function of blocking or reducing short-circuit current in the event of an internal short circuit or an external short circuit.
