This work systematically summarizes the fundamental principles behind the development of fluorine-free electrolytes (FFEs), including the selection and optimization of salts, solvents, additives, and binders. It highlights the environmental and safety motivations for eliminating fluorine from battery electrolytes and provides a detailed comparison between traditional fluorinated systems and emerging fluorine-free alternatives. The review also presents various molecular design strategies and engineering approaches for achieving high-performance, sustainable battery systems without relying on fluorinated compounds.

2.Critical Assessment of Recent Advances and Performance in Multiple Battery Chemistries
The article offers an in-depth evaluation of the latest innovations and achievements in FFEs across a wide range of battery chemistries, including lithium, sodium, potassium, magnesium, calcium, and zinc batteries. It discusses specific examples of successful FFE formulations, their electrochemical performance, and the unique challenges encountered in each system. The review further addresses the roles of fluorine-free salts such as LiBOB, NaBOB, and others, as well as the impact of novel solvents and additives on battery stability, safety, and cycle life.

3.Identification of Key Challenges and Future Research Directions for Commercialization
This review identifies the major obstacles that must be overcome for the widespread adoption of FFEs, such as achieving sufficient electrochemical stability, high ionic conductivity, and robust interphase formation. It emphasizes the need for continued research into the degradation mechanisms, compatibility with high-voltage electrodes, and scalable manufacturing processes. The article concludes by outlining future research priorities and the potential of FFEs to enable environmentally sustainable, high-performance batteries that support a circular economy.
