The Cu-Li phase diagram in [Massalski2] was redrawn from [1986Pel]. No intermediate phase was shown in the phase diagram.

Figure 1 shows the Cu-Li phase diagram calculated by [2009Gas]. The existence of a new phase, \(\hbox{Cu}_{2}\hbox{Li}_{3},\) was concluded by analyzing temperature dependence of the electromotive force for Cu-Li alloys with various compositions.
