Abstract: The residue sulfate ions (SO₄^2-) occurs in an adsorption and complex salt manner which are significant influence the electrochemical properties of LiNi_1/3Co_1/3Mn_1/3O₂ as cathodes materials for lithium-ion batteries. Compare with different SO₄^2- concentration electrochemical performance reveals that low SO₄^2- concentration (0.28%) demonstrated a better charge/discharge cycle performance than the high SO₄^2- concentration (0.48%) of LiNi_1/3Co_1/3Mn_1/3O₂, it maintains a capacity of 148.9 mAh·g⁻¹ with a coulomb efficient of 91 % after 100 cycles which superior to the SO₄^2- concentration (0.48%) circulation coulomb efficient of 87%, respectively.
