Molten salts includes fluorides, chlorides and carbonates melts for use in several electrochemical processes. Aluminium electrolysis is the predominant field of work but also electrowinning of Titanium, Iron, Magnesium, Silicon and Rare Earth Metals (REM) covers our research activities. Recently our research activity also cover recycling and electro refining of critical materials (REE elements mainly). Liquid metal battery for future storage of renewable energy is another field of research.
