Sol Gel vs Solid State Synthesis of the Fast Lithium-Ion Conducting Solid State Electrolyte Li7La3Zr2O12Substituted with Iron

Composite electrolytes containing lithium ion conducting polymer matrix and ceramic filler are promising solid-state electrolytes for all solid-state lithium ion batteries due to their wide electrochemical stability window, high lithium ion conductivity and low electrode/electrolyte interfacial resistance. In this study, we report on the polymer infiltration of porous thin films of aluminum-doped cubic garnet fabricated via a combination of nebulized spray pyrolysis and spin coating with subsequent post annealing at 1173 K. This method offers a simple and easy route for the fabrication of a three-dimensional porous garnet network with a thickness in the range of 50 to 100 µm, which could be used as the ceramic backbone providing a continuous pathway for lithium ion transport in composite electrolytes. The porous microstructure of the fabricated thin films is confirmed via scanning electron microscopy. Ionic conductivity of the pristine films is determined via electrochemical impedance spectroscopy. We show that annealing times have a significant impact on the ionic conductivity of the films. The subsequent polymer infiltration of the porous garnet films shows a maximum ionic conductivity of 5.3 × 10−7 S cm−1 at 298 K, which is six orders of magnitude higher than the pristine porous garnet film.

Safety And Stability

All-solid-state Li-ion batteries (ASSLiBs) are considered as promising next-generation energy storage devices, and the one that is based on oxide ceramic solid-state electrolyte (SSE) has attracted much attention for its high safety and stability in ambient conduction compared with that of used sulfur and polymer SSEs. However, the undeformable nature of the ceramic SSEs brings new issues such as poor interface bonding, limited contact area and limited cathode utilization for the ASSLiBs. In addition, the interface reaction and resistance are also obstacles for ASSLiBs application. In this review, we focus on the synthesis and electrochemical properties, interface modification and failure mechanism of ASSLiBs. Finally, perspectives of future researches on the ceramic SSEs-based ASSLiBs are discussed.
