![]() One safer method is to use a pipe cutter and split the battery case in the middle. It's risky, as the battery can short and overheat. It comes as a long sheet of lithium metal, that quickly tarnishes in air. Lithium can be extracted from lithium batteries, as shown by NurdRage is his video. It also has a high boiling point, of 1330 ☌. Molten lithium is extremely reactive and will react with almost all ceramic materials, therefore lithium is only melted in crucibles made of special metals, such as molybdenum. This makes it difficult to melt it under oil (a common tactic for removing tarnish from the other alkali metals). In addition, lithium has the highest melting point of all alkali metals, at roughly 180 degrees Celsius. Since these solvents are liquid only at very low temperatures or under high pressure, storing lithium in them is impractical. The only organic hydrocarbons lighter than lithium are liquid methane (465 kg/m 3), liquid propane (493.5 kg/m 3), liquid propylene (514.4 kg/m 3). It is lighter than any hydrocarbon oil, which causes the metal to float in the oil is stored. Lithium has a density of only 534 kg/m 3, making it the lightest metal and solid element at standard conditions. Because of this, lithium metal is often used in coolants for heat transfer applications. Lithium has the highest specific heat capacity of any solid element, 3.58 kJ/(kg It is soft enough to be cut with a knife. Lithium metal can dissolve in anhydrous ammonia and ethylenediamine, forming its electride salt. It has the lowest reduction potential in aqueous solution, and gram-for-gram (as well as mole-for-mole) has a higher energy content than cesium. Ĭontrary to popular belief, lithium, not cesium, is the most reactive element on the periodic table. It is the only alkali metal that cannot be safely melted in a glass container, as it reacts exothermically with glass almost immediately. ![]() Molten lithium is probably the most powerful reducing agent known, and will explode on contact with almost anything non-metallic, including wood, glass and concrete. It is also used in organometallic synthesis in the form of organolithium compounds such as n-butyllithium and tert-butyllithium, although they are extremely rarely used by the amateur chemist, mainly because they're very dangerous (pyrophoric and caustic). Such fires are difficult to extinguish, requiring dry powder extinguishers (class D). As noted by NurdRage in his video where he extracted lithium from an energizer battery, this flame is incredibly bright, so welding goggles should be used if this reaction is attempted. Lithium will burn in air, and it tends to burn with a red-crimson flame. ![]() In open air, it quickly forms a layer of oxide as well as nitride, and if the air also contains water vapors and carbon dioxide, lithium hydroxide and lithium carbonate.Ĥ Li + O 2 → 2 Li 2O 6 Li + 2 N 2 → 2 Li 3N 2 Lithium, like all the alkali metals reacts violently with water, releasing hydrogen and can ignite, but this reaction is slightly less violent than the other alkali metals. ![]()
