"textContent": "Disclosed is a cathode for a lithium secondary battery and a lithium secondary battery comprising the same. The cathode may include a current collector, a first composite layer formed from a mixture of olivine-type lithium iron phosphate cathode active material powder and a binder on the current collector, and a second composite layer formed from a mixture of olivine-type lithium iron phosphate cathode active material powder and a binder on the first composite layer. A specific surface area of the olivine-type lithium iron phosphate cathode active material powder in the second composite layer may be at least 1.2 times larger than that of the olivine-type lithium iron phosphate cathode active material powder in the first composite layer. The cathode for a lithium secondary battery has excellent safety, high energy density, and high output performance.",
