锂盐一步法熔融电解制金属锂的方法技术

锂盐一步法熔融电解制金属锂的方法，电解槽内石墨阳极(6)产生的氯气经由氯气回输管(8)抽往反应池(13)上分解槽的高温熔融室(11)，由下而上地经过多孔钛筛板(16)，同熔融的碱性锂盐发生反应，生成氯化锂继续电解，由于反应迅速自下而上不断在阴极生成金属锂。氯气事实上成为运载锂离子的载体，往返循环于电解槽内分解室和高温熔融室之间，而不再向外排出，不但提高生产效率和金属锂品质，而且，避免了外排氯气所需的辅助设备以及其影响，另外，节省的相关浓缩结晶、离心分离、高温烘干、锂锭熔化和真空蒸馏等工艺，显著节省工序，降低设备和生产成本，为下游工艺和产品应用带来了巨大的商机。

Method for preparing lithium metal by one-step molten electrolysis of lithium salt

Method of one-step electrolysis of molten salts of lithium metal, graphite anode electrolytic tank (6) produced by chlorine chlorine infusion tube (8) pumped to the reaction tank (13) high temperature melting chamber on the decomposition groove (11), from the bottom up through the porous titanium plate (16), alkaline and molten lithium the reaction of lithium chloride to generate electrolysis, due to rapid response time in the generation of lithium metal cathode from bottom to top. In fact a carrier carrying chlorine lithium ion, between cyclic in electrolytic cell decomposition chamber and the melting chamber, instead of outwards, not only improve the production efficiency and the quality of lithium metal, and avoid the auxiliary equipment required for the efflux of chlorine and its influence, in addition, save the relevant crystallization and centrifugal separation high temperature drying, lithium ingot melting and vacuum distillation process, significant savings in equipment and processes, reduce production costs, to bring enormous business opportunities for the downstream process and product application.
