In particular, the Li 2 MF 6 (M = Zr, Ti, Si, Ge) materials possess the best combination of ionic conductivity and electrochemical and chemical stability, which surpasses the performance of common binary fluoride and oxide coatings. In this review we have presented an overview of fluorinated electrode materials for high-energy batteries.
As a new type of chemical material with excellent performance, fluorine-containing chemicals can effectively improve the electrochemical performance of lithium-ion batteries .
Fluorine containing battery chemicals or modified fluorine containing battery chemicals are helpful to improve the above phenomenon , . It is also very important to develop fluorine-containing chemicals for sodium ion batteries.
Preparation of Fluorine-Containing Lithium-Ion Battery Chemicals Four kinds of fluorine-containing chemicals, PVDF, LiPF 6, LiBF 4 and FEC, used in lithium-ion batteries are introduced, and the basic preparation methods of these fluorine-containing lithium-ion battery chemicals are reviewed.
In addition, the ability of fluorinated electrolyte additives to conveniently and flexibly enhance the performance of rechargeable batteries, without needing to majorly modify the core components of the battery, presents a notable advantage for commercialization, as it imposes lower requirements on industrial production lines.
Incorporating fluorine into battery components can improve the energy density, safety and cycling stability of rechargeable batteries.
