Figure 2. (A) Schematic open-circuit energy diagram for a Li|SSE|Li_xMyO₂ battery system where μLi and μLi_xMyO₂ represent the chemical potentials of Li and the cathode materials, respectively.

(C) The interphase formed between SSE and lithium metal with (a) thermodynamically stable two-dimensional interphase, (b) mixed ionic-electronic conducting interphase (MCI) formed due to thermodynamic instability of SSE with lithium, and (c) growth of stable three-dimensional interphase due to the poor electronic conductive reaction products.
