Abstract: Provided are an anode active material for a lithium secondary battery, a method for preparing same, and a lithium secondary battery including same. An anode active material for a lithium secondary battery according to the present invention includes: active particles by means of which lithium ions may be absorbed/released; and a coating layer coated on the surface of the active particles, wherein the coating layer includes a first material which is a hollow nanofiber and a second material which is a carbon precursor or LTO.

Abstract: A cathode active material precursor for a rechargeable lithium battery including hollow nanofibrous carbon may be a composite cathode active material precursor for a rechargeable lithium battery including hollow nanofibrous carbon; and a cathode active material precursor joined to the skeleton of the hollow nanofibrous carbon, wherein the cathode active material precursor includes a metal composite of Ma(PO4)b.nH2O (Formula 1-1) or M(OH)c.nH2O (Formula 1-2), and a composite cathode material for a rechargeable lithium battery may be made electrically conductive by including a carbon substance, and the outside or the inside of the hollow nanofibrous carbon as well is charged with an olivine type lithium phosphate cathode material. Consequently, it is possible to improve electrical conductivity, and to ensure a high capacity density suitable for high-capacity batteries since the cathode active material is charged on the inside of the hollow nanofibrous carbon as well without wasting any space.
