Abstract
(EN)
The present invention relates to a positive electrode active material particle powder which comprises a compound having at least a crystal system belonging to a space group R-3m and a crystal system belonging to a space group C2/m, and which is characterized by having a specific peak intensity ratio and a Mn content as determined by the equation: Mn/(Ni+Co+Mn) of 0.55 or more by mole, containing an element A (wherein the element A represents at least one element selected from Si, Y and Zr) in an amount of 0.03 to 5wt%, and having a tap density of 0.8 to 2.4 g/cc and a pressed density of 2.0 to 3.1 g/cc. The positive electrode active material particle powder can be produced by burning a mixture comprising a precursor particle powder containing elements A, Mn, Ni and/or Co and a lithium compound.
