Uses of Lithium chloride:
Commercial applications of Lithium chloride:
Lithium chloride is mainly used to produce lithium metal by electrolysis of a LiCl/KCl melt at 450 °C (842 °F).
LiCl is also used as a brazing flux for aluminum in automobile parts.
It is used as a desiccant for drying air streams.
Lithium chloride is used in organic synthesis in more specialized applications, e.g., as an additive in the Stille reaction.
Also, it can be used in biochemical applications to precipitate RNA from cellular extracts.
Lithium chloride is also a flame colorant to produce dark red flames.
Lithium chloride, one of the most well-known mood stabilizers with antisuicidal effects, is currently utilized as an agent for acute mania and a maintenance treatment in bipolar disorder.
Lithium metal is produced by electrolysis of lithium chloride and potassium chloride, which melts at 450°C.
High-purity lithium chloride is used as the feedstock in the process and makes about 99.5% pure lithium metal.
Molten lithium is contained in a carbon steel pot, while the chlorine gas is collected in a stainless steel or glass pipe for applications in other processes.
The molten lithium flows into a collecting tank and is later cast into ingots.
A mesh or stainless-steel screen separates the two compartments to prevent the products from mixing.
Other Applications of Lithium Chloride
Lithium chloride is used as a flame colorant to form dark crimson flames.

Additionally, lithium chloride can be used as a hygrometer.
This deliquescent salt forms a self-solution when exposed to air.
The equilibrium LiCl concentration in the resulting solution is directly related to the relative humidity of the air.
The percent relative humidity at 25 °C (77 °F) can be estimated, with minimal error in the range 10–30 °C (50–86 °F), from the following first-order equation: RH=107.93-2.11C, where C is solution LiCl concentration, percent by mass.

Precautions
Lithium salts affect the central nervous system in a variety of ways.
While citrate, carbonate, and orotate salts are currently used to treat bipolar disorder, other lithium salts, including chloride, were used in the past.
For a short time in the 1940s, lithium chloride was manufactured as a salt substitute for people with hypertension, but this was prohibited after the toxic effects of the compound (tremors, fatigue, nausea) were recognized.
It was, however, noted by J. H. Talbott that many symptoms attributed to lithium chloride toxicity may have also been attributable to sodium chloride deficiency, to the diuretics often administered to patients who were given lithium chloride, or to their underlying conditions.
Acute and short-term toxicity of Lithium Chloride:
Animal
The LD50 of lithium chloride following subcutaneous administration in mice was ∼17–19 mmol kg−1 (∼700–800 mg kg−1).
The acute oral LD50 in rats is ∼500 mg kg−1.
Acute lithium exposure elicits excessive urination and polydipsia.
Lithium hydride is highly toxic (the only lithium salt to be so) (Bernard, 2022; McKnight et al., 2012).
Human
Lithium hydride rapidly converts to lithium hydroxide in contact with water.
Lithium hydride is corrosive to all tissues, outer skin, and lung cells.
