Anode

Schematic illustrations of the SEI on a) uncoated Si and b) AlF3-coated Si electrodes. In coated Si electrodes, the SEI formation mechanism involves the transformation of AlF3 to Li-Al-F compounds (e.g., Li3AlF6).

AlF3 coatings can help extend lifetime and performance of silicon anode materials 153
