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.
