▎ 摘 要
NOVELTY - Lithium metal and lithium alloy moldings are produced by contacting solutions of metallic lithium in ammonia (Li(NH3)4+n, where n is 0-10) with metallic or electronically conductive deposition substrates, and removing ammonia at - 100-100 degrees C by overflowing with inert gas or at pressures of 0.001-700 mbar, so that the remaining lithium is deposited on the deposition substrate and/or is doped with lithium or alloyed by it. USE - The process is useful for preparing lithium metal and lithium alloy moldings for use as anodes in galvanic cells. ADVANTAGE - The process is carried out in the absence of transition metal-containing catalysis or hydrogen acceptors by thermal decomposition of a solution of pure metallic lithium in ammonia, preferably of pure liquid lithium bronze, at temperatures of at maximum 100 degrees C and in contact with deposition substrates. In this process, ammonia is completely removed via the gas phase in reversal of the formation reaction, so that elemental lithium metal remains, which is deposited on the surfaces of the apparatus used and deposition substrate located in it. The lithium metal and lithium alloy moldings (bodies/impressions) are prepared in the presence of lithium bronze, with an Li:NH3 molar ratio of 1:4, contains the lowest ammonia-content, and as a result, requires the least ammonia for production.
