Descrizione generale
Lithium nitrate is a white, crystalline salt that is soluble in water, ethanol, methanol, pyridine, ammonia, and acetone. Importantly, it is also highly soluble up to 5 wt% in ether-based solvents such as dimethoxyethane (DME) and 1,3-dioxolane (DOL), but only soluble up to 1 wt% in carbonate-based solvents like ethylene carbonate (EC) and diethtyl carbonate (DEC).
Lithium nitrate is produced by reacting nitric acid and lithium carbonate, which evolves carbon dioxide and water. The resulting material is purified and dried.

Applicazioni
Researchers and manufacturers use lithium nitrate in the synthesis of many lithium compounds. Our 99.999% lithium nitrate is well-suited as a reagent for solid-state syntheses of lithium metal oxides, especially where purity is of high importance, for example, when making products whose fundamental properties are under investigation.
Our 99.999% lithium nitrate is also well-suited for use as an additive to electrolytes in lithium-sulfur batteries and lithium metal batteries. Lithium nitrate can passivate the surface of lithium metal and suppress the redox shuttle of the dissolved lithium polysulfides on the lithium anode. In one study, the addition of 0.3 M LiNO3 nearly doubled the gravimetric capacity of lithium-sulfide batteries. Another study found that the dissolution of 1 to 5 wt% LiNO3 to the electrolyte suppressed growth of lithium dendrites and extended cycle lifetimes. Similarly beneficial effects of lithium nitrate as an additive have been observed with Li2S cathodes, carbon nanofiber-encapsulated sulfur cathodes, cobalt sulfide (Co3S4) cathodes, and polyacrylonitrile-sulfur composite cathodes. Even lithium metal anodes with LiNi0.8Co0.15Al0.05O2 (NCA) cathodes with LiNO3 added to the electrolyte showed higher coulombic efficiencies and suppressed dendrite formation compared to the electrolyte without LiNO3.
