摘要
在LiCl-KCl体系中,653~693K下电解制备金属锂,分别研究了在氩气、空气、氧气以及氮气气氛下,水蒸气含量对金属锂电解电流效率的影响。结果表明,氧气和水蒸气共同作用会对金属锂电解产生不利影响。对反应过程进行了热力学计算并分析不同条件下水分对电解的影响机理。
Metal lithium was produced from molten LiCl-KCl melt under 653-693 K.Different atmosphere effects of Ar,air,N2 and O2 on current efficiency of LiCl-KCl electrolysis were investigated.The results show that oxygen and water vapor have disadvantageous effects on lithium electrolysis.Thermodynamic calculation on reaction process is performed,and effect mechanism of water on electrolysis under different conditions is analyzed.
