Lithium difluoro(sulfato)borate (LiBF2SO4) is investigated as a lithium salt for non-aqueous electrolytes for LiMn2O4 cathode in lithium-ion batteries. Inductively coupled plasma-atomic emission spectrometry analysis is used to analyze the Mn dissolution. Scanning electron microscopy and AC impedance measurements analysis are used to analyze the formation of the surface film on the surface of LiMn...
To seek a promising candidate for 5V electrolytes, fluorine-free lithium bis(oxalato) borat (LiBOB) is chosen as the lithium salt, and lithium difluoro(sulfato) borate (LiBSO4F2) is investigated as an additive for the stabilization of a high-voltage LiNi0.5Mn1.5O4 cathode. Cyclic voltammetry test, AC impedance measurement and scanning electron microscopy (SEM) analysis are used to examine the electrochemical...
In this paper, the electrochemical performance of a new low-temperature electrolyte, 0.9 mol L −1 lithium oxalyldifluoroborate (LiODFB)/LiBF 4 (5.365:1, by mass) mixed salts in the ethylene carbonate (EC)/dimethyl sulfite (DMS)/ethyl methyl carbonate (EMC) mixed solvent (1:1:3, by volume, the same below), is studied to seek the promising candidate for advanced low-temperature...
