Cathode active material for lithium secondary batteries with high safety, method of preparing the same, and lithium secondary batteries comprising the same |
摘要 |
The present invention relates to a cathode active material for lithium secondary batteries with high safety, a method of preparing the same and lithium secondary batteries comprising the same. The cathode active material of the present invention comprises a lithium metal oxide secondary particle core portion formed by aggregation of lithium metal oxide primary particles; and a shell portion formed by coating the secondary particle core portion with an olivine-structured lithium iron phosphate oxide. The cathode active material of the present invention allows to manufacture lithium secondary batteries with improved safety, especially overcharge characteristics. |
