Intercalation of Lithium Hydride into Graphite and Electrochemical Behavior

The lithium hydride does not intercalate by itself, on the contrary, the reaction of hydrogen in LiC 6 leads to a mixture of LiH and high stages lithium intercalated compounds. However, in the presence of a heavy alkali metal (potassium or cesium), LiH intercalates to give quatenary phases M 2 LiHC 8s , s being the stage. Those compounds contain large amounts of intercalated metal per carbon atom (M/C = 3/8s) and may be interesting as electrode material for secondary batteries.
