Working principle of an ionic liquid interlayer during pressureless lithium stripping on Li6.25Al0.25La3Zr2O12 (LLZO) garnet‐type solid electrolyte
Abstract
No pressure: This work demonstrates the working principle of an ionic liquid interlayer to enhance the stripping performance of lithium metal in contact with a garnet solid electrolyte. Detailed analysis, including galvanostatic electrochemical impedance spectroscopy and cryogenic FIB-SEM, shows that pores forming in lithium metal during stripping are compensated to a great extent, which improves the stripping performance up to over 15 mAh cm−2. Solid-state-batteries employing lithium metal anodes promise high theoretical energy and power densities. However, morphological instability occurring at the lithium/solid–electrolyte interface when stripping and plating lithium during cell cycling needs to be mitigated. Vacancy diffusion in lithium metal is not sufficiently fast to prevent pore formation at the interface above a certain current density during stripping. Applied pressure of several MPa can prevent pore formation, but this is not conducive to practical application. This work investigates the concept of ionic liquids as “self-adjusting” interlayers to compensate morphological changes of the lithium anode while avoiding the use of external pressure. A clear improvement of the lithium dissolution process is observed as it is possible to continuously strip more than 70 μm lithium (i. e., 15 mAh cm−2 charge) without the need for external pressure during assembly and electrochemical testing of the system. The impedance of the investigated electrodes is analyzed in detail, and contributions of the different interfaces are evaluated. The conclusions are corroborated with morphology studies using cryo-FIB-SEM and chemical analysis using XPS. This improves the understanding of the impedance response and lithium stripping in electrodes employing liquid interlayers, acting as a stepping-stone for future optimization.
