Method for producing positive electrode active material for lithium ion secondary battery |
| abstract |
Provided is a positive electrode active material capable of improving electron conductivity and reducing the positive electrode resistance of a secondary battery without reducing the discharge capacity of the secondary battery. A method for producing a positive electrode active material according to the present invention comprises mixing a transition metal-containing composite compound particle containing lanthanum and a lithium compound to obtain a lithium mixture, and mixing the lithium mixture with a compound having a melting point equal to or lower than the melting point of the lithium compound. After calcining at a temperature, the lithium mixture is calcined at a firing temperature ranging from 725C to 1000C. It is preferable to use lithium carbonate as the lithium compound. In this case, the calcination temperature is set in the range of 600 ° C to 723 ° C. The lanthanum-containing transition metal-containing composite compound particles are preferably obtained by a coprecipitation method, and the lanthanum element is preferably uniformly dispersed in the particles.
