  "textContent": "Disclosed are a cathode active material for lithium seco ndary batteries, a method for preparing the same, and lithium secondary batteries comprising the same. The cathode active material for lithium secondary batteries comprises a lithium metal oxide secondary particle core formed by aggregation of a plurality of lithium metal oxide primary particles; a first shell formed by coating the surface of the secondary particl e core with a plurality of barium titanate particles and a pl urality of metal oxide particles; and a second shell formed b y coating the surface of the first shell with a plurality of olivine-type lithium iron phosphate oxide particles and a plu rality of conductive material particles. The cathode active m aterial for lithium secondary batteries allows manufacture of lithium secondary batteries having excellent thermal stabili ty, high-temperature durability and overcharge safety.",
