Lithium imide is an inorganic compound with the chemical formula Li 2 N H. This white solid can be formed by a reaction between lithium amide and lithium hydride. [1] LiNH 2 + LiH → Li 2 NH + H 2. The product is light-sensitive and can undergo disproportionation to lithium amide and characteristically red lithium nitride. 2 Li 2 NH → LiNH 2 ...
Lithium amide or lithium azanide is an inorganic compound with the chemical formula LiNH 2. It is a white solid with a tetragonal crystal structure. [1] Lithium amide can be made by treating lithium metal with liquid ammonia: [2] 2 Li + 2 NH 3 → 2 LiNH 2 + H 2. Lithium amide decomposes into ammonia and lithium imide upon heating. [3]
In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] The compounds are structurally related to acid anhydrides , although imides are more resistant to hydrolysis.
Lithium and fluorine are both extremely corrosive. Lithium ignites on contact with air, and fluorine ignites most fuels on contact, including hydrogen. Fluorine and the hydrogen fluoride (HF) in the exhaust are very toxic, which makes working around the launch pad difficult, damages the environment, and makes getting a launch license more ...
It is commonly used as Li-ion source in electrolytes for Li-ion batteries as a safer alternative to commonly used lithium hexafluorophosphate. [3] It is made up of one Li cation and a bistriflimide anion.
The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow. [1] Pairing lithium and ambient oxygen can theoretically lead to electrochemical cells with the highest possible specific energy.
Lithium imide can also be formed under certain conditions. Some research has explored this as a possible industrial process to produce ammonia since lithium hydride can be thermally decomposed back to lithium metal. Lithium nitride has been investigated as a storage medium for hydrogen gas, as the reaction is reversible at 270 °C. Up to 11.5% ...
Burning lithium metal produces lithium oxide. Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen at temperatures above 100 °C: [3] 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C [3] [2] 2 Li ...
