Cathode active material added with fluorine compound for lithium secondary batteries And Method of producing thereof

摘要

The present invention relates to a cathode active material for lithium secondary battery, and provides a structurally stable cathode active material for lithium secondary battery having improved battery charging/discharging characteristics, life span characteristics, high voltage characteristics and high rate capability, by synthesizing a powdered fluorine compound as an additive for cathode active materials, and adding the powdered fluorine compound to a cathode active material for lithium secondary battery to produce a fluorine compound-added cathode active material for lithium secondary battery.
