<P>PROBLEM TO BE SOLVED: To provide a lithium secondary battery with the improved balance of a discharge capacity, load characteristics, and safety. <P>SOLUTION: This lithium secondary battery with a positive electrode contains manganese containing lithium-nickel compound oxide particles 2 and lithium-cobalt compound oxide particles 1. The weight of the manganese containing lithium-nickel compound oxide particles 2 is less than 50 wt% of the total weight of the manganese containing lithium-nickel compound oxide particles 2 and the lithium-cobalt compound oxide particles 1, and the average particle size of the manganese containing lithium-nickel compound oxide particles 2 is made 1/2 or smaller than the average particle size of the lithium-cobalt compound oxide particles 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
