A research team led by Professor Li Chilin from the Shanghai Institute of Ceramics (SIC) of the Chinese Academy of Sciences has recently made progress in conversion-type lithium-fluoride batteries.
Among various fluorinated compounds used in batteries, poly (vinylidene fluoride) (PVDF) binders and lithium hexafluorophosphate (LiPF 6) salts have been successfully commercialized as binders for Ni-rich [Ni 1–x–y Co x Mn y]O 2 (NCM) cathodes and electrolytes, respectively .
In particular for Li-driven fluoride conversion, heterogeneous precipitation and coverage of insulating lithium fluoride (LiF) on the whole electrode surface impedes the internal chemical reaction between active fluoride and lithium, causing large voltage hysteresis and low available capacity.
Provided by the Springer Nature SharedIt content-sharing initiative Fluorides have been identified as a key ingredient in interphases supporting aggressive battery chemistries.
Conclusion Stricter regulations targeting fluorinated compounds, such as PFAS, have necessitated a reevaluation of commonly used fluorinated components in battery technologies, such as PVDF binder and LiPF 6 electrolyte.
