锂电解槽的热场分析

为了提高金属锂电解槽的电解效率,以600 A锂电解槽为研究对象,利用多物理场仿真软件对金属锂电解槽在不同电压和不同外辅热温度下进行三维热场模拟,并结合实验进行分析。结果表明,在同一水平面上,电解槽温度较高的区域在阴阳极之间,阳极表面温度要高于阴极表面,越靠近阳极其熔盐电解质温度越高,电解槽四周温度相对较低;当直流电压为5.5 V、外辅热温度为370℃时,热场分布合理,电解效率相对较高。研究结果可为该型电解槽结构优化提供参考。

Thermal field analysis of lithium electrolytic cell

In order to improve the electrolysis efficiency of lithium metal electrolysis cell,the multi-physical simulation software was used to simulate the three-dimensional heat field of lithium metal electrolysis cell under different voltages and different external auxiliary heat temperatures based on 600 A lithium electrolysis cell.And combined with the experimental analysis.The results show that on the same level,the higher temperature area of the electrolytic cell is between the anode and cathode,the anode surface temperature is higher than the cathode.The closer to the anode,the higher the molten salt electrolyte temperature is.When the DC voltage is 5.5 V and the external auxiliary heat temperature is 370℃,the thermal field distribution is reasonable and the electrolytic efficiency is relatively high,which provides a reference for the structure optimization of this electrolytic cell.
