摘要：
This work presents a novel study on electrochemical codeposition of Mg-Li alloys on molybdenum in KCl-LiCl (50:50wt%) melts containing different concentrations MgCl2 at 943 K. Cyclic voltammograms showed that the underpotential deposition (UPD) of lithium on pre-deposited magnesium leads to the formation of liquid Mg-Li alloys. The codepositon of Mg and Li happens when the current intensity exceeds 0.59 A cm(-2) in KCl-LiCl melts containing 5 wt % MgCl2. alpha, alpha + beta, and beta phases Mg-Li alloys with different lithium contents were obtained by galvanostatic electrolysis from KCl-LiCl melts with different concentrations MgCl2.
