Abstract: The present invention relates to a lithium secondary battery, more particularly, to a lithium secondary battery in which a low-cost positive electrode active material is applied and a negative electrode active material of lithium metal is formed on the positive electrode side, and to a preparation method thereof. The lithium secondary battery according to the present invention can be produced at a low unit cost of production because it employs a complex combined from relatively inexpensive Co, CoO, Co3O4 and Li2O, instead of LiCoO2 which is a common positive electrode active material, and the lithium secondary battery is also easy to mass produce because of its simple manufacturing process since LiCoO2 is synthesized through an electrochemical reaction due to operating of the battery without a separate heat treatment process.

Abstract: The present invention relates to a method for preparing a magnetic iron oxide-graphene composite, a magnetic iron oxide-graphene composite prepared thereby and a composition for electromagnetic wave shielding including the same, and since graphene is prepared from a stage 1-GIC using FeCl3, magnetic particles in the form of FeOx are naturally formed on the surface of graphene during the preparation process. In addition, a magnetic material is formed on the surface of graphene while the defects of graphene are minimized, and thus the magnetic iron oxide-graphene composite prepared according to the present invention can be useful as an electromagnetic wave absorber.

Abstract: The present invention relates to a Li-rich antiperovskite compound and the use thereof, and more particularly, to a Li-rich antiperovskite compound having a novel structure in which a dopant is substituted in a Li3OCl compound, wherein the dopant is substituted for an O site rather than an anionic Cl site, as known in the art, and an electrolyte using the same. The Li-rich antiperovskite compound has high lithium ion conductivity and excellent thermal stability, and thus can be applied as an electrolyte for lithium secondary batteries which are driven at a high temperature.

Abstract: The present invention relates to a Li-rich antiperovskite-coated LCO-based lithium complex, a method of preparing the same, and a positive electrode active material and a lithium secondary battery, both of which include the LCO-based lithium complex. When a lithium complex in which a coating layer of a compound having a lithium-rich antiperovskite (LiRAP) crystal structure is formed on surfaces of LCO-based particles is applied as the positive electrode active material, the lithium complex is favorable for batteries which are operated at a high voltage, has high lithium ion conductivity, and can be applied to lithium secondary batteries which are driven at a high temperature due to high thermal stability.
