Abstract
Disclosed is a current collector prepared by coating a primer on a metallic base and a magnesium secondary battery including the same. The primer includes a conductive material and a polymer material and enhances adhesive strength between a cathode current collector and an active material, thereby maintaining stability in an operating voltage range of the battery without increasing internal resistance.
