  • A CATHODE ACTIVE MATERIAL COATED WITH MANGANESE PHOSPHATE FOR A LITHIUM SECONDARY BATTERY AND A PREPARATION METHOD OF THE SAME
    Publication number: 20150349339
    Abstract: The present invention relates to a cathode active material for a lithium secondary battery and a preparation method thereof, and particularly, to a cathode active material for a lithium secondary battery having improved battery characteristics because of manganese phosphate uniformly coated on the surface of a Ni-rich cathode active material, and a preparation method thereof. According to the present invention, because manganese phosphate is uniformly coated on the surface of the Ni-rich cathode active material, a side reaction of the electrolyte is inhibited and a lithium secondary battery having excellent power characteristics, high temperature cycle life characteristics, and thermal stability can be prepared.
