Fig. 5. A proposed scheme for obtaining high-performance SSEs from a complex material space of divalent ion SSEs. Data mining will play a key role in capturing promising divalent ion SSE materials as the basis, and an integrated strategy across subsequent data mining, theoretical calculations and modeling, and experiments will be used to reveal the ionic migration mechanism and structure-performance relationships of the potential SSEs. Finally, the ionic migration of these SSEs will be accelerated by considering various optimization strategies.
Fig. 4. Different anion structures of closo-type materials and halogen analogs. X represents different halogen atoms (F, Cl, Br, and I) [58]. Note that halogens’ atomic volumes are larger than the hydrogen atom, and electrostatic potential distribution is more heterogeneous, which could lead to a higher cation ion migration barrier [60].
Fig. 3. Illustration of Mg²⁺ migration in ternary spinel MgSc₂Se₄. Mg²⁺ will overcome an energy barrier to migrate from a to b (i.e., the “tet-oct-tet” pathway). A larger atomic volume is expected to result in a larger triangle plane for a more facile ionic migration.
Fig. 2. The structure framework of Mg(BH₄)₂. (a) Coordination configuration of Mg²⁺ and four [BH₄]^-. (b) Structure of a cubic Mg(BH₄)₂. Mg²⁺ is located at the center of a regular tetrahedron constructed by four [BH₄]^- anions.
Fig. 1. Statistics of divalent-ion-conducting materials published during the past 40 years. (a) Distribution of divalent-ion-conducting SSEs as a function of temperature. The right frame shows the counts of SSEs in a diverse range of ionic conductivity. (b) Reports of Mg-, Zn-, and Ca-ion SSEs, where the diverse colors present different SSEs in the upper picture, and the lower picture shows the optimized strategies in Mg-based SSEs.
