TL;DR: Results obtained from lithium symmetrical cells suggest that the quality of the LLZO/lithium interface has a significant impact on the device lifetime and surface polishing can effectively remove Li2CO3 and dramatically improve the interfacial properties.

TL;DR: This article begins with the discussion of various rechargeable batteries and associated important scientific questions in the field, followed by a review of synchrotron X-ray based analytical tools and their successful applications and their fundamental insights into these scientific questions.

TL;DR: This study presents the fabrication of LLZO heterostructured solid electrolytes, which allowed direct correlation of surface microstructure with the electrochemical characteristics of the interface, and low area specific resistances were achieved, removing a significant obstacle toward practical implementation ofSolid electrolytes in high energy density batteries.

TL;DR: The phase transition from garnet to “non-garnet” and the different sintering behavior of Ga and Al stabilized LLZO are identified as important factors in determining the electrochemical properties, illustrating that understanding the structure–properties relationships in this class of materials allows practical obstacles to its utilization to be readily overcome.

TL;DR: The results suggest that the interfacial impedances of these devices is critically dependent upon specific characteristics of the solid electrolyte and how it is prepared, and this has important implications for the operation of solid-state lithium batteries containing LLZO.
