Abstract: The present invention relates to an anode active material for lithium secondary battery and a lithium secondary battery including the same, and more specifically it relates to an anode active material for lithium secondary battery in which the a lithium ion diffusion path in the primary particles is formed to exhibit specific directivity, and a lithium secondary battery including the same. The cathode active material for lithium secondary battery of the present invention has a lithium ion diffusion path exhibiting specific directivity in the primary particles and the secondary particles, thus not only the conduction velocity of the lithium ion is fast and the lithium ion conductivity is high but also the cycle characteristics are improved as the crystal structure hardly collapses despite repeated charging and discharging.

Abstract: A cathode for lithium secondary batteries coated with a slurry including an active material, a binder and a solvent, and further including a polymerization inhibitor, is disclosed. Gelation of the slurry is prevented during production of the cathode so that adhesion of the slurry is enhanced, thus achieving improved coating properties of the cathode and facilitating the coating of the slurry.
