The main components of the SEI (Solid Electrolyte Interphase) layer vary but typically include a mix of organic and inorganic compounds. Common components are:
- Inorganic compounds:
- Lithium Carbonate (Li2CO3)
- Lithium Fluoride (LiF)
- Lithium Oxide (Li2O)
- Lithium Hydroxide (LiOH)
- Lithium Halides (e.g., LiCl)
- Organic compounds:
- Lithium Alkyl Carbonates (e.g., ROCO2Li)
- Lithium Alkoxides (e.g., CH3OLi)
- Polymers and oligomers from electrolyte decomposition
The exact composition can depend on the type of electrolyte used and the nature of the electrode material.
