The study and development of rechargeable energy storage systems such as batteries, [1] fuel cell, [2] electrochemical capacitors and solar cells, among others, [3] have attracted considerable attention in recent years. In particular, the rechargeable graphite-based ion batteries are considered as a promising alternative for energy storage applications easily adapted to industry, and nowadays are one of the most studied and widely known technologies. In this work, we present an experimental study of the intercalation process of aluminium fluoride (AlF3) in highly oriented pyrolytic graphite (HOPG) by direct evaporation under ultra-high vacuum and room temperature conditions. We characterize the system in different instances of AlF3 dosing by STM, XPS, and RBS.[4] The interpretation of our results was assisted by DFT.
