The present invention provides an electrode material containing at least one first lithium metal oxide selected among the compounds represented by the following chemical formula (1), the first lithium metal oxide consisting of primary particles and containing secondary particles having an average particle diameter (D50) of 1 mm to 15 mm. (1-x)LiM′O_(2-y) A_y -xLi_2MnO_(3-y′) A_y′ (1) In the formula, M′ is Mn_aM_b; M is at least one selected from the group consisting of Ni, Ti, Co, Al, Cu, Fe, Mg, B, Cr, Zr, Zn, and 2-cycle transition metals; A is at least one selected from the group consisting of PO_4, BO_3, CO_3, F, and NO_3 negative ions, and 0<x<1; 0<y<=0.02; 0<y′<=0.02; 0.5<=a<=1.0; 0<=b<=0.5; and a+b=1. |
