Process for the Preparation of Lithium Metal and Lithium Alloy Mouldings
13 Jul 23
The invention relates to a process for the production of lithium metal and lithium alloy mouldings, wherein solutions of metallic lithium in ammonia having the composition Li(NH3)4+n and n=0-10 are brought into contact with metallic or electronically conductive deposition substrates and the ammonia is removed at temperatures of −100 to 100° C. by overflowing with inert gas or at pressures of 0.001 to 700 mbar, so that the remaining lithium is deposited on the deposition substrate or/and it is doped with lithium or alloyed by it.
