Popis:	The residue sulfate ions (SO42-) occurs in an adsorption and complex salt manner which are significant influence the electrochemical properties of LiNi1/3Co1/3Mn1/3O2 as cathodes materials for lithium-ion batteries. Compare with different SO42- concentration electrochemical performance reveals that low SO42- concentration (0.28%) demonstrated a better charge/discharge cycle performance than the high SO42- concentration (0.48%) of LiNi1/3Co1/3Mn1/3O2, it maintains a capacity of 148.9 mAh·g−1 with a coulomb efficient of 91 % after 100 cycles which superior to the SO42- concentration (0.48%) circulation coulomb efficient of 87%, respectively.
