    摘要： Disclosed is a separator for a lithium secondary battery and a lithium secondary battery comprising the same. The separator may include a thermoplastic polyolefin-based polymer porous sheet and an aramid-based non-woven fabric sheet stacked on at least one surface of the polyolefin-based polymer porous sheet, wherein the polyolefin-based polymer sheet and the aramid-based non-woven fabric sheet are adhered with an adhesive, and the adhesive loses an adhesive performance at 80° C. or more to separate the two sheets. The separator has a shut-down function and excellent high-temperature shape stability.

    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.
