Lithium is extremely soft and the lightest metal out of the 103 metallic elements (specific gravity 0.5). Silver-white in color, lithium reacts strongly with water and even at room temperature turns black when exposed to nitrogen. The foil is wrapped into a coil and packed in an inert gas state when shipped.
Applications of lithium foil
Lithium foil is mainly used on the anodes of cylindrical and button-type lithium rechargeable batteries. Depending on the battery’s use, pure lithium and lithium-aluminum foil alloys are available.
