英文摘要	The effect of the lithium boron oxide glass coating on the electrochemical performance of LiNi1/3Co1/3Mn1/3O2 has been investigated via solution method. The morphology, structure, and electrochemical properties of the bare and coated LiNi1/3Co 1/3Mn1/3O2 are characterized by scanning electron microscopy, X-ray diffraction, electrochemical impedance spectroscopy, and charge-discharge tests. The results showed that the lattice structure of LiNi1/3Co1/3Mn1/3O2 is not changed after coating. The coating sample shows good high-rate discharge performance (148 mAh g^-1 at 5.0 C rate) and cycling stability even at high temperature (with the capacities retention about 99% and 87% at room and elevated temperature after 50 cycles). The Li⁺ diffusion coefficient is also largely improved, while the charge transfer resistance, side reactions within cell, and the erosion of Hydrofluoric Acid all reduced. Consequently, the good electrochemical performances are obtained.
