It was investigated kinetics of гаге earth metals (La, Pr, Sm, Lu) incorporation to aluminium and their influence on next magnesium and lithium incorporation from aprotic organic solutions of their salts to interval of temperature +50. ,.-20°C.
It was established, that the temperature of solution influences to velocity of incorporation process so to time of saturation of solid solution and to velocity of next process of electxocrystallization 1MC.
It was pointed, that electronic system of La³⁺ and Lu³⁺ ions, having highest stability, generated higher stability of phase β-LiAl in structure of Li-Mg-REE-Аl electrode.
