One problem with the lithium–sulfur design is that when the sulfur in the cathode absorbs lithium, volume expansion of the Li x S compositions occurs, and predicted volume expansion of Li 2 S is nearly 80% of the volume of the original sulfur. [35] This causes large mechanical stresses on the cathode, which is a major cause of rapid degradation.
Lithium sulfide is the inorganic compound with the formula Li 2 S. It crystallizes in the antifluorite motif, described as the salt (Li + ) 2 S 2− . It forms a solid yellow-white deliquescent powder.
It can be prepared by metathesis reaction between sodium azide and lithium nitrate or lithium sulfate solutions: NaN 3 + LiNO 3 → LiN 3 + NaNO 3 2 NaN 3 + Li 2 SO 4 → 2 LiN 3 + Na 2 SO 4 [3] It can also be prepared by reacting lithium sulfate with barium azide. Ba(N 3) 2 + Li 2 SO 4 → 2 LiN 3 + BaSO 4 [2]
Lithium permanganate is an inorganic compound with the chemical formula LiMnO 4. It can be produced by the reaction of lithium sulfate and barium permanganate, and the trihydrate LiMnO 4 ·3H 2 O can be crystallized from the solution. It decomposes violently at 199 °C: [2] 2 LiMnO 4 → Li 2 O + 2MnO 2 + ³/₂ O 2 ↑
Lithium hydroxide is an inorganic compound with the formula LiOH. It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide.
Lithium forms salt-like derivatives with all halides and pseudohalides. Some examples include the halides LiF, LiCl, LiBr, LiI, as well as the pseudohalides and related anions. Lithium carbonate has been described as the most important compound of lithium. [100] This white solid is the principal product of beneficiation of lithium ores.
