The 0.7Li(CB11H12–0.3Li(CB11H12)/Li interfacial resistance was calculated to be 0.78 Ω cm2.
Electrochemical impedance spectroscopy was used to measure the interfacial resistance.
These side reactions result in an increase in interfacial resistance, greatly degrading battery performance during repeated cycling.
This interfacial resistance is strongly moisture-sensitive.
0.7Li(CB11H12–0.3Li(CB11H12) shows markedly high stability against the lithium metal anode in terms of potential window, interfacial resistance, voltage polarization, and lithium plating/stripping cycling.
Liu, T. et al. Achieving high capacity in bulk-type solid-state lithium ion battery based on Li6.75La3Zr1.75Ta0.25O12 electrolyte: interfacial resistance.
The lithium/SPE interfacial resistance decreases linearly with the temperature.
This system appears to exhibit no significant interfacial resistance.
However, the performance of LLZO-based SSBs is limited by the large cathode/electrolyte interfacial resistance.
This interfacial resistance is quite noticeable, as it is far lower than those of other solid electrolyte/Li interfaces reported to date3,14,16,18,19,34,35,36,37.
The interfacial resistance between 0.7Li(CB11H12–0.3Li(CB11H12) and lithium metal was examined with a frequency response analyzer (3532-80, Hioki) using a Li/0.7Li(CB11H12–0.3Li(CB11H12)/Li cell.
