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.read more

Challenges for Rechargeable Li Batteries

TL;DR: In this paper, the authors reviewed the challenges for further development of Li rechargeable batteries for electric vehicles and proposed a nonflammable electrolyte with either a larger window between its lowest unoccupied molecular orbital and highest occupied molecular orbital (HOMO) or a constituent that can develop rapidly a solid/ electrolyte-interface (SEI) layer to prevent plating of Li on a carbon anode during a fast charge of the battery.
