Abstract: The present invention relates to a cathode for a lithium secondary battery, a manufacturing method therefor, and a lithium secondary battery comprising the cathode. The cathode for a lithium secondary battery comprises a cathode active material layer formed to contain a very low content of conductive material at the outermost side thereof, whereby the cathode can have high thermal stability when an internal short-circuit of a battery occurs, and can achieve high-power properties when applied to a secondary battery.
