What Is The Stability Of Libh4?

LiBH4, also known as lithium borohydride, is a white crystalline solid that is highly reactive with water and air. It has been extensively studied as a potential hydrogen storage material for fuel cells and other energy applications.

In terms of its stability, LiBH4 is generally considered to be thermally stable up to around 250°C, above which it starts to decompose into lithium hydride (LiH) and boron hydride (B2H6). However, the presence of impurities or additives can significantly affect its stability and decomposition behavior.

For example, doping LiBH4 with transition metals such as Ti, Fe or Co can improve its hydrogen storage properties, but can also decrease its thermal stability. On the other hand, adding metal halides such as LiCl or MgCl2 can enhance its stability and prevent decomposition at high temperatures.

Overall, the stability of LiBH4 can depend on various factors such as composition, purity, processing conditions, and its intended use.
