Abstract

The binary Li–Al system is characterized by formation of 3 stable compounds, namely LiAl (NaTl structure type (ST), space group (SG) Fd-3m), Li3Al2 (own ST, SG R-3m) and Li9Al4 (own ST, SG C2/m), and one metastable – LiAl3 (AuCu3 ST, SG Pm-3m). The last compound forms sometimes as a by-product in electrochemical lithiation of Al-contained intermetallics because of stabilization by impurities or electrolyte [1]. In this case small B atoms occupy octahedral voids of the LiAl3 crystal structure.
