    摘要： Provided are an anode active material for a lithium secondary battery, a method of preparing the same and a lithium secondary battery comprising the same. The anode active material for a lithium secondary battery includes a carbonaceous material core; and a shell formed outside of the carbonaceous material core. The shell includes a plurality of spinel-type lithium titanium oxide particles, and a plurality of metal oxide particles, wherein the metal belongs to group 4 or 13 of the periodic table, the metal oxide particles filling voids formed by the carbonaceous material and the plurality of spinel-type lithium titanium oxide particles. The anode active material for a lithium secondary battery has the metal oxide shell, and thus has the improved conductivity, a high output density, and consequently excellent electrical characteristics. The lithium secondary battery manufactured using the anode active material ensures safety sufficiently.

    摘要： A lithium secondary battery capable of preventing explosion or firing caused by the increase of inner pressure due to misusage is disclosed. The lithium secondary battery includes an electrode assembly having an anode plate, a cathode plate and a separator, a package having a receiving portion for receiving the electrode assembly and sealed and filled with electrolyte together with the electrode assembly, and an adhesive layer at least partially formed on an outer surface of the package. The lithium secondary battery functions as an explosion-proof safety device for preventing the package from exploding due to abrupt breakage of the package when the package is expanded due to the increase of inner pressure of the battery over a critical value.
