Disclosed are an electrode active material for lithium secondary batteries, comprising at least one selected from compounds represented by the following formula 1, and a lithium secondary battery comprising the same.LiMoMOA&#x2003;&#x2003;(1)

Electrode active material and lithium secondary battery comprising the same

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.

Cathode current collector coated with primer and magnesium secondary battery comprising the same

Disclosed are a novel compound, a method for preparing the same, and a lithium secondary battery comprising the same. More specifically, disclosed are a compound in which five MOoctahedrons are bonded to one another around one MOoctahedron such that the MOoctahedrons share a vertex, to form hollows and Li cations substituted instead of Na cations using an ion substitution method are present in the hollows, and a crystal structure thereof is not varied even upon intercalation and deintercalation of Li cations, a method for preparing the same, and a lithium secondary battery comprising the same as a cathode active material.
