From Liquid- to Solid-State Batteries: Ion Transfer Kinetics of Heteroionic Interfaces

Abstract: Hybrid battery cells combining liquid electrolytes (LEs) with inorganic solid electrolyte (SE) separators or different SEs and polymer electrolytes (PEs), respectively, are developed to solve the issues of single-electrolyte cells. Among the issues that can be solved are detrimental shuttle effects, decomposition reactions between the electrolyte and the electrodes, and dendrite propagation. However, the introduction of new interfaces by contacting different ionic conductors leads to other problems, which cann… Show more

“…Overall the Li 6 PS 5 Cl|Li 3 InCl 6 charge transfer resistance is roughly one order of magnitude smaller than the bulk contribution and is 59 Ω cm 2 compared to 589 Ω cm 2 for the bulk process at 193 K, thus it is negligible at room temperature. This small resistance for Li ion charge transfer at the hetero‐contact Li 6 PS 5 Cl|Li 3 InCl 6 supports the general finding that the interface resistance two inorganic SEs is small, once good contact is achieved [16] …”

“…That is to say, the ionic CT resistance ( R LPEI‐CT and R PEI‐CT ) is caused by the desolvation/solvation of Li ions at the LPEI and PEI, while the interphase resistance ( R LPEI and R PEI ) is attributed to the limited conductivity of formed interphase. [ 15b,25,26 ] Besides, the constant phase elements (CPE) are used to describe the electrical double layer at the LPEI (CPE LPEI‐dl ) and the PEI (CPE PEI‐dl ), which is also relevant with the ionic CT process. [ 15b ] As shown in Figure 4b, the values of R SUM gradually reduce from 69.8 Ω (12 h) to 17.1 Ω (90 h) owing to the sustained release of PPC.…”

“…Considering the variety of experimental data on that topic already acquired, we recently published a review on the existing data, as well studying the impact of the solid electrolyte, the solvent, and the conducting salt on the growth and magnitude of the SLEI's resistance. [ 86 ]…”
