Lithium Foil is a pure lithium metal product available in a range of 13 variations. Lithium is the lightest metal with a density of 0.53 g/cm3. It has excellent heat transfer properties and is soft enough to be cut with a knife. Lithium foil is used in batteries as an anode material due to its high electrochemical potential, as well as in alloys with aluminum and magnesium to reduce density. Our Lithium Foil range meets the needs of research and industry across a broad spectrum of applications.
