Importance of Fluorine in High Voltage Electrolytes for LNMO||SiGr Cell Chemistry

and effective interphase formation. In comparison to cells with non-fluorinated electrolytes, the galvanostatic cycling performance demonstrates a considerable improvement, leading to a doubling of the achievable cycle life. Roll-over failure observed in the electrolyte with non-fluorinated solvents could be effectively suppressed for over 300 cycles and the resulting electrolyte formulation with fluorinated solvents is non-flammable. Additionally, by fine-tuning the electrolyte formulation, the extent of acetylcholinesterase inhibition, an indication of substance toxicity of the aged electrolyte could be reduced.
