Phase diagram for the Li-Si system (Braga et al. 1995). a phase diagram; b temperature vs electrochemical potential of the Li vs. Li-liquid (Braga et al. 1995) and c (Liang et al. 2017) (adapted with permission of the copyright holder). \( {\overline{\mu}}_{Li}-{\overline{\mu}}_{Li}^{0, liq}=0\Longrightarrow {\mu}_{Li}-{\mu}_{Li}^{0, liq}=- zF\Delta V= RTln{a}_{Li} \), ΔV = E(vs. Li − liquid)[mV], and aLi is the activity of the lithium in the mixture. In a) and b) it is signed 400 K in red dotted line for mutual comparison. In c 677 K is signed for comparison with Fig. 6a)
