General description

Lithium bromide is a crystalline solid with high refractive index. It is widely used in the field of rechargeable batteries, organic synthesis, and optical lenses.

Application

Lithium bromide(LiBr) can be used:
  • An electrolyte additive for lithium-sulfur batteries to enhance their rate performance and cycling stability.
  • To prepare poly (vinyl alcohol) (PVA) fibers. The addition of LiBr improves the mechanical properties of the polymer fibers.
  • To fabricate a surface passivation layer for silicon solar cells to enhance photoluminescence intensity.

An investigation of electron and hole transfer to oxidized guanine bases in DNA is reported. Guanine in DNA was preferentially oxidized by Br(2)(*-) at 298 K to 8-oxo-7,8-dihydro-guanine (8-oxo-G) and higher oxidation products. HPLC-EC analysis of irradiated DNA shows that

[reaction: see text] The alkanesulfonamide "safety-catch" resin has proven useful for Fmoc-based synthesis of C-terminal peptide thioesters. We now report that the yield of isolated thioester can increase significantly when the cleavage reaction is carried out in 2 M LiBr/THF

Both symmetrical and nonsymmetrical trans-2,3-diaryloxiranes are regio- and stereoselectively opened by the LiBr/Amberlyst 15 system. In the case of symmetrical trans-stilbene oxide, the syn- versus anti-bromohydrins ratio ranged between 88/12 and 30/70, by varying the reaction temperature from 20 to

The structure of starch molecules is relevant to nutrition and industrial applications. Size-exclusion chromatography (SEC, also known as GPC) of native starch generally suffers non-satisfactory repeatability and reproducibility of the dissolution and separation. This work combines two polar organic solvents:

Complex Hydrides: A New Category of Solid-state Lithium Fast-ion Conductors

Research and development of solid-state lithium fast-ion conductors is crucial because they can be potentially used as solid electrolytes in all-solid-state batteries, which may solve the safety and energy-density related issues of conventional lithium-ion batteries that use liquid (farmable organic) electrolytes.
