Abstract

The effects of lithium bisoxalatoborate (LiBOB) and lithium difluorooxalatoborate (LiDFOB) as electrolyte additives on the high voltage cycling performance of lithium-ion cells are investigated. With traces of 0.2 wt. % LiBOB or 0.5 wt. % LiDFOB added, the cycling performance of Li/LiNi _1/3Co_1/3Mn_1/3O₂ cells charged to 4.6 V is improved. The electrochemical impedance spectroscopy (EIS) suggests that the additives can decrease impedance. The results of scanning electron microscopy (SEM) of the LiNi_1/3Co_1/3Mn_1/3O ₂ cathode indicated the existence of this film. X-ray photoelectron spectroscopy (XPS) indicates the additives are justified to modify cathode surface films and suppress electrolyte oxidation reactions on the cathode surface. In addition, differential scanning calorimetric (DSC) studies show that thermal stability of fully charged Li_1-xNi_1/3Co _1/3Mn_1/3O₂ cathode is improved in the presence of additives.
