CATHODE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY INCLUDING SAME |
摘要 |
Disclosed is a cathode for a lithium secondary battery and a lithium secondary battery comprising the same. The cathode for a lithium secondary battery 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 0.8 times or less 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 stability, high energy density, and improved cycle life characteristics. |
