Abstract
We report the hydrogenation temperature and pressure dependence of hydrogen absorption capacity in CaC6. In addition, the structure and phase stability of hydrogenated CaC6, LiC6 and KC8 has been investigated using X-ray diffraction and Raman spectroscopy. It is found that the hydrogen chemisorption in both CaC6 and LiC6 leads to either metastable or higher stage intermediate compounds but eventually leaves completely deintercalated graphite by forming stable metal hydrides. In contrast hydrogenation of KC8 generates a restaged ternary hydride compound. The phase stability of hydrogenated compounds is discussed in the text based on the observed experimental results and correlated to the thermodynamic and kinetic aspects of intercalated metal.
