Lithium-ion transfer through the lanthanum lithium titanate/LiClO 4 -concentrated propylene carbonate (PC) solution interface was investigated by the ac impedance method. Charge-transfer resistance (R ct ) across the solid/liquid interface was observed and the interfacial activation energy was calculated from temperature dependency of R ct . The activation energies for interfacial Li + -ion transfer were invariable for 1 mol dm -3 and Li + /PC ) 1/3 (by molar ratio) solution, but about 10 kJ mol -1 higher for Li + /PC ) 1/2 solution. Raman spectra showed that the contact ion pair was formed in the Li + /PC ) 1/2 solution. These results suggest that the activation energy for the cleavage of the ion-ion interaction process was higher than that for the desolvation process; that is, the cleavage of the ion-ion interaction was the rate-determining step for the solid/concentrated solution.

“…In Japan, the Lithium Battery Energy Storage Technology Research Association (LIBES) began contracted research and development of large-scale LIBs of 20-30 kWh for use in dispersed battery energy storage systems and electric vehicles as part of the government's New Sunshine (NSS) Program [100,101]. In 1997, the basic plan was revised [102] and great importance was placed on the development of high-performance battery modules of 2-3 kWh, as shown in Table IV [103,104]. The modules are manufactured by combining several unit cells of 200-360 Wh.…”

“…2 Besides, in some extreme cases, the risks associated with a volatile and flammable organic liquid electrolyte have also been one of the main limitations on the application of lithium-ion batteries in EVs. 3,4 Over the past two decades, replacement of the traditional organic liquid electrolyte by a non-flammable inorganic solid electrolyte with high conductivity in all-solid-state lithium-ion batteries has been considered as a potential approach to address these issues. [5][6][7] Due to their high lithium-ion conductivity, wide electrochemical and temperature windows, as well as excellent mechanical behaviors for constructing a solid-solid interface between an electrolyte and electrode, sulfide solid electrolytes have been the focus of considerable attention.…”

All-solid-state lithium-ion batteries that use sulfide solid electrolytes have attracted much attention due to their high safety and wide electrochemical window. In this study, highly oriented pyrolytic graphite (HOPG) and 75Li2S-25P2S5 (mol%) glass were used as a model graphite negative electrode and a sulfide solid electrolyte, respectively. Interfacial lithium-ion transfer between 75Li2S-25P2S5 glass and the HOPG electrode was studied by AC impedance spectroscopy measurements. The activation energy of the interfacial lithium-ion transfer was estimated to be around 37 kJ mol −1 , which was much smaller than that at the interface between organic liquid electrolytes and HOPG electrode, indicating that the lithium-ion transfer at the interface between 75Li2S-25P2S5 glass and HOPG electrode proceeded quite rapidly. Furthermore, surface deposition of TiO2 and surface oxidation on HOPG electrodes were performed using the atomic layer deposition (ALD) method. Interfacial lithium-ion transfer between 75Li2S-25P2S5 glass and ALD-modified-HOPG electrodes was also investigated. The activation energies of the interfacial lithium-ion transfer were slightly higher than that of HOPG, but the resistance of the charge-transfer process was lower, indicating that the affinity of the HOPG electrode for the glass electrolyte was improved by surface modification.
