Lithium-Ion Transfer at the Interface Between Lithium-Ion Conductive Ceramic Electrolyte and Liquid Electrolyte-A Key to Enhancing the Rate Capability of Lithium-Ion Batteries

In this study, lithium-ion transfer through the electrode/electrolyte interface was examined using a model interface composed of a lithium-ion-conductive ceramic and liquid electrolytes to focus on lithium-ion transfer. Lithium-ion transfer resistances at the interface and their activation energies were evaluated by impedance spectroscopy. The activation energies were quite large and consistent with the interaction between lithium-ion and solvents in an electrolyte as determined by a theoretical calculation.
