There are several solvents that can be used to wash LiPF6 salt from electrodes as anode for Lithium-ion batteries (LIBs). Some common choices include:
Acetonitrile
Methanol
Ethanol
Isopropanol
N-Methylpyrrolidone (NMP)
Dimethylformamide (DMF)
Propylene carbonate (PC)
Tetrahydrofuran (THF)
Ethylene carbonate (EC)
Diethyl carbonate (DEC)
It is important to note that some solvents may be more effective than others depending on the specific application and the type of electrode material used. It is also important to consider the potential impact of the solvent on the performance and safety of the battery before using it for washing. Additionally, it is recommended to test a small amount of the sample before using on a large scale, to check for any potential detrimental effects on the electrode.
