Preparation of High Weight Loading Lithium Borohydride in Carbon Aerogels

Abstract:

We describe approaches using modified carbon aerogels for increasing the weight loading of LiBH4. Large pore volume carbon aerogels were prepared with a sol-gel method and a polymethyl methacrylate (PMMA) microsphere template. Compared to those without using templates, the pore volume has been up to 3.8 times with a PMMA template. After incorporation into carbon aerogels, the weight loading of LiBH4 has reached 80%. Nitrogen absorption/desorption measurements show that more than 95% free space of carbon aerogels has been incorporated with LiBH4. Rama spectra suggest that there is no PMMA or chemical reaction during the synthesis of LiBH4/carbon aerogel composites.
