Fluorinated components in the form of salts, solvents and/or additives are a staple of electrolytes for high‐performance Li‐ and Na‐ion batteries, but this comes at a cost. Issues like potential toxicity, corrosivity and environmental concerns have sparked interest in fluorine‐free alternatives. Of course, these electrolytes should be able to deliver performance that is on par with the electrolytes being in use today in commercial batteries. This begs the question: Are we there yet? This review outlines why fluorine is regarded as an essential component in battery electrolytes, along with the numerous problems it causes and possible strategies to eliminate it from Li‐ and Na‐ion battery electrolytes. The examples provided demonstrate the possibilities of creating fully fluorine‐free electrolytes with similar performance as their fluorinated counterparts, but also that there is still a lot of room for improvement, not least in terms of optimizing the fluorine‐free systems independently of their fluorinated predecessors.
