Due to the long and complex process of hydrometallurgy, fluoride-containing substances are more prone to migration and transformation, hence the heightened risk of fluorine pollution. Residual metal fluorides are leached. As previously mentioned, LiF is produced during both the usage stage of the battery and the pretreatment stage of recycling.
It can be seen that fluorine has been widely used in liquid lithium-ion battery electrolytes, cathode, and anode electrode materials. Of particular note is that in the field of solid-state lithium-ion batteries, which have not yet been commercialized, fluorides also play a crucial role .
They are widely used in personal electronic devices, home appliances, new energy vehicles, and energy storage systems (as shown in Fig. 1 a). According to EVTank's “China Lithium-ion Battery Industry Development White Paper (2024)”, the global shipment of LIBs reached 1,202.6 GWh in 2023.
Additionally, developing fluorine-free electrolytes or reducing the use of fluorinated substances in batteries can address the fluorine pollution issue at its source. For example, Bin and Yang et al., proposed using H 2 O as the solvent for the electrolyte, which offers a sustainable alternative to traditional fluorinated solvents.
Herein, we unveil the critical role of interfacial defluorination kinetics of localized high-concentration electrolytes (LHCEs) in regulating lithium dendrite formation, thereby determining the performance of low-temperature LMBs.
To decrease the risk of fluorine pollution during the recycling of spent batteries, it is essential to separate or remove all fluorinated substances from the battery as soon as possible when the battery is opened.
