英文摘要	A new class of fluorinated sulfones, ß-fluorinated sulfones, were designed and synthesized as electrolyte solvents for high voltage lithium-ion batteries. While the oxidation potential of ß-fluorinated sulfones is slightly lower than that of a-fluorinated sulfones, it is still significantly higher than the oxidation potential of regular sulfones, which already possess fairly high anodic stability. However, ß-fluorinated sulfones exhibit a significant decrease in reduction potential compared to a-fluorinated sulfones, rendering them more stable towards graphite anodes. Moreover, the reduced lithium solvating power of ß-fluorinated sulfones compared to regular sulfones mitigates the transition metal dissolution of cathodes. Taken together, these middle ground properties of ß-fluorinated sulfone-based electrolytes enable the very stable long-term cycling of graphite?LiNi0.6Co0.2Mn0.2O2 full cells. The outstanding performance of ß-fluorinated sulfones designed by applying the "golden middle way"paves a new path for the development of an effective electrolyte system. © 2021 The Royal Society of Chemistry.
