Cathode And Lithium Secondary Battery Manufactured Using Same

Abstract: According to the present invention, a cathode is provided comprising: a current collector; a first cathode active material layer formed on the current collector; and a second cathode active material layer formed on the first cathode active material layer, wherein the first cathode active material layer and the second cathode active material layer each contain lithium iron phosphate, a fluorine-based binder, a first hydrogenated nitrile butadiene rubber with a weight average molecular weight (Mw) of 10,000 g/mol to 100,000 g/mol, a second hydrogenated nitrile butadiene rubber with a weight average molecular weight (Mw) of 130,000 g/mol or more, and a conductive material, and the ratio (P2/P1) of the weight P2 of fluorine contained in the second cathode active material layer to the weight P1 of fluorine contained in the first cathode active material layer is 1 or less.
