· JVASP-51286· LiBBr2

Lithium bromide (LiBBr2) is an inorganic ionic ceramic compound composed of lithium and bromine elements, belonging to the halide salt family of ceramics. This material is primarily investigated in research contexts for absorption cooling systems and as an electrolyte component in advanced battery and energy storage applications, where its hygroscopic properties and ionic conductivity make it relevant for thermal management and electrochemical devices. LiBBr2 offers potential advantages in absorption chiller systems where traditional refrigerants are being phased out, though engineering adoption remains limited to specialized thermal and electrochemical applications rather than commodity industrial use.
