Disclosed is lithium manganese having high power and excellent high-temperature stability. Specifically disclosed is a lithium manganese particle powder which has a primary particle diameter of 1 μm or more, an average particle diameter of behavioral particles (D50) of 1 to 10 μm (inclusive), which substantially forms a single crystal particle, and which is represented by the chemical formula: LiMnYO[Y = Al, Mg or Co; 0.03 <= x <= 0.15, 0.05 <= y <= 0.20], wherein the element Y is homogeneously dispersed in the interior of the particle, the I(400)/I(111) ratio is 33% or more, and the I(440)/I(111) ratio is 16% or more. |
