发明名称 出力特性と安全性が向上した混合正極活物質及びこれを含むリチウム二次電池
摘要 Provided are a mixed cathode active material having improved power characteristics and safety, and a lithium secondary battery including the same. More particularly, the present invention relates to a mixed cathode active material which may assist power in a low SOC range to widen an available state of charge (SOC) range and may simultaneously provide improved safety by blending substituted LFP, in which operating voltage is adjusted by substituting a portion of iron (Fe) with other elements such as titanium (Ti), in order to prevent a rapid increase in resistance of manganese (Mn)-rich having high capacity but low operating voltage in a low SOC range (e.g., a SOC range of 10% to 40%), and a lithium secondary battery including the mixed cathode active material.
