Kurzbeschreibung (Abstract)

All-solid-state lithium ion batteries (ASS-LIBs) are promising due to their safety and higher energy density as compared to that of conventional LIBs. Over the next few decades, tremendous amounts of spent ASS-LIBs will reach the end of their cycle life and would require recycling in order to address the waste management issue along with reduced exploitation of rare elements. So far, only very limited studies have been conducted on recycling of ASS-LIBS. Herein, we investigate the recycling of the Li₇La₃Zr₂O₁₂ (LLZO) solid-state electrolyte in a LiFePO₄/LLZO/ Li₄Ti₅O₁₂ system using a hydrometallurgical approach. Our results show that different concentration of the leaching solutions can significantly influence the final product of the recycling process. However, it was possible to recover relatively pure La₂O₃ and ZrO₂ to re-synthesize the cubic LLZO phase, whose high purity was confirmed by XRD measurements.

Alternatives oder übersetztes Abstract:	Alternatives Abstract Sprache Recycling of solid-state batteries, which are expected to become extremely important in the energy industry over the next decade, is often very complex due to the solid electrolyte. Here, recycling of all-solid-state lithium ion batteries has been approached by a combination of mechanical/hydrometallurgical methods. Promising results confirm the recovering of the solid-electrolyte. Englisch
