Positive electrode active material powder, method for producing same, and nonaqueous electrolyte secondary battery |
abstract |
The present invention is a positive electrode active material particle powder comprising a compound having at least a crystal system belonging to the space group R-3m and a crystal system belonging to the space group C2 / m, and the compound is at least Li and Mn and Co and / or Ni (A) of the maximum diffraction peak at 2? = 20.8 ± 1 ° of the powder X-ray diffraction chart using the Cu-K? Line of the positive electrode active material particle powder and the (A) / (b) of the intensity (b) of the maximum diffraction peak is 0.02 to 0.5, the Mn content of the positive electrode active material particle powder is Mn / (Ni + Co + Mn) And 0.001 to 3% by weight of boron. The positive electrode active material particle powder can be obtained by firing a mixture containing Mn, Ni and / or Co-containing precursor particle powders, a lithium compound and a boron compound in the range of 500 to 1500 ° C. The charge / discharge capacity and cycle characteristics can be improved by the positive electrode active material particle powder. |
