Sulfide-based all-solid-state lithium metal batteries have attracted significant attention from both industry and academia due to their potential for achieving high energy density and high safety. However, the cycling performance of lithium-negative-type all-solid-state lithium metal batteries is limited by the continuous generation of non-active lithium during charge-discharge cycles. The non-active lithium consists of two parts: (1) non-active metallic lithium (also known as "dead lithium"), which is caused by uneven lithium dissolution leading to electron-ion pathway interruption, and (2) non-active lithium-containing compounds, which are formed at the interface (electro)chemical reactions between the lithium metal anode and the solid-state electrolyte. The presence of non-active lithium significantly affects the electrochemical performance of the battery. Therefore, accurately quantifying these two types of non-active lithium during the battery cycling process is crucial for understanding the failure process of all-solid-state lithium metal batteries.
Based on this, the research team led by Yong Yang from Xiamen University, for the first time, utilized in situ solid-state nuclear magnetic resonance (NMR) technology to analyze the failure mechanisms of lithium metal anodes in different sulfide-based all-solid-state lithium batteries. Through quantitative studies of non-active lithium in the system, they revealed the formation mechanisms of the two types of dead lithium in all-solid-state batteries. In addition, they also investigated the corrosion issue of the lithium metal anode in all-solid-state lithium metal batteries and clarified the relationship between corrosion rate and lithium metal morphology. This work deepens the understanding of the failure mechanisms of all-solid-state lithium metal batteries and provides important guidance for their further development. The work was published in the top-tier international journal Nature Communications, with Ziteng Liang and Yuxuan Xiang as co-first authors.
In the paper, it can be seen that some of the electrochemical performance was tested using NEWARE's battery testing equipment (CT-4008). This equipment is a star product in the CT-4000 series, which not only includes testing devices for button batteries but also features a cell charge-discharge testing cabinet designed for square pouch batteries and other specific requirements. The testing cabinet offers different charge-discharge modes to meet your testing needs with just one click.
