Cathode And Lithium Secondary Battery Manufactured Using Same
Abstract: A cathode according to an embodiment of the present invention comprises a cathode active material layer disposed on at least one surface of a cathode current collector. The cathode active material layer contains a lithium transition metal phosphate, a fluorine-based binder, and a conductive material, and the lithium transition metal phosphate includes a carbon coating layer formed on the surface thereof. In the cathode active material layer, the ratio (B/A) of the total weight B of the fluorine-based binder to the total weight A of carbon of the conductive material and the lithium transition metal phosphate is 0.7 to 1.7.
