PURPOSE: A cathode composition is provided to coexist high output and cycle properties in a non-aqueous electrolytic secondary battery and to enhance operability and yield in battery manufacturing by suppressing viscosity increase of cathode slurry. CONSTITUTION: A cathode composition for non-aqueous electrolytic secondary batteries comprises lithium-transition metal composite oxide represented by Li_aNi_(1-x-y)Co_xM^1_yW_zM^2_wO_2 and boron compound which includes boron element and oxygen element. In the chemical formula, 1.0<=a<=1.5, 0<=x<=0.5, 0<=y<=0.5, 0.002<=z<=0.03, 0<=w<=0.02, 0<=x+y<=0.7, M^1 is one or more selected from a group comprises of Mn and Al, and M^2 is one or more selected from a group including Zr, Ti, Mg, Ta, Nb and Mo.
