Intercalation of Lithium Hydride into Graphite and Electrochemical Behavior

Abstract

Abstract The lithium hydride does not intercalate by itself, on the contrary, the reaction of hydrogen in LiC6 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 M2LiHC8s, 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.
