Degree of single crystal formation = ∑ i = 1 n 4 π 3 × R i 3 n [0002] In Equation (A), R is a radius of an i grain which is measured when an electrode prepared by using the positive electrode active material is subjected to an ion-milling treatment and a cross-section of the electrode is then analyzed by electron backscatter diffraction (EBSD), wherein R is a value measured in µm units, but a value substituted into Equation (A) is a unitless number that does not include units, and n is the total number of grains measured by the electron backscatter diffraction (EBSD) analysis.",
