Figure 3. Schematic illustration of: (A) Li-ion transport via hopping effect in the solid-matrix channels of QSSLMBs; (B) The importance of liquid components in surface engineering of QSSE; (C) The effect of Li-MOF on lithium-ion conduction and the crystallinity of the polyethylene oxide (PEO) matrix; (D) Improvement of the adhesion and ionic contact for better Li-ion transport by modifying the surface chemistry of the MOFs; (E) Three proposed Li conduction mechanisms in MOF-based QSSEs; (F) Ionic conductivities of MOF-688(Mn) and MOF-688(Al) obtained from experimental measurements, and theoretical calculations using Green-Kubo relations (GK), Nernst-Einstein equation (NE), and simple hopping model (hopping).
