In this work, we examine the role of a cathode composite microstructure composed of solid-state electrolyte (SSE) with different particle sizes. A composite made of LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> (NCM811) and fine-particle Li<sub>6</sub>PS<sub>5</sub>Cl (LPSC) shows a more uniform distribution of SSE on the surface of NCM811 particles, ensuring intimate contact. Moreover, the composite features reduced tortuosity, which enhances Li ion conduction. These microstructural advantages result in significantly reduced charge transfer resistance, helping to suppress mechanical distortion and electrochemical degradation during cycling under low-pressure conditions. As a result, the fine-LPSC cathode composite exhibits enhanced cycling stability at a moderate stack pressure of 2 MPa, outperforming its coarse-LPSC counterpart. Our finding confirms the important role of microstructure design in enabling high-performance ASSBs operating under low-pressure conditions.</p>","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 2","pages":"966–974 966–974"},"PeriodicalIF":19.3,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike traditional pyrometallurgy and hydrometallurgy, which often destroy valuable materials, direct recycling seeks to recover and restore functional components, preserving the integrity of active materials. However, this method faces significant technical hurdles, particularly due to the complex design of LIBs and the degradation of key components over time.

Phase segregation under illumination in mixed halide perovskites is one of the major issues in stable device operation. Herein, we rationalize illumination power dependent phase segregation phenomena, including two thresholds between which phase segregation occurs, and the reversal of phase segregation. Our experimental observation combining confocal photoluminescence mapping with in situ Raman spectroscopy supports the halide oxidation model. We observed phase segregation beyond the illuminated area, while the illuminated area remained mixed. Reversal of phase segregation under illumination was also observed. We propose that the spatial distribution of phase segregation is driven by halide oxidation and diffusion of the products through mass flow, as verified by light- and spatial-dependent lattice halide vibrations. Our insights into phase segregation may provide new perspectives for manipulating phase segregation by local light intensity for dynamically tunable optoelectronics.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"28 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether or not such pulverization persists in all solid state lithium batteries (ASSLBs) remains unclear. Herein, we show that pulverization of the Li<sub><i>x</i></sub>Al anode is mitigated in ASSLBs due to the applied external stack pressure, thus preventing the mechanical failure of the Li<sub><i>x</i></sub>Al anode in ASSLBs. Moreover, electron microscopy investigation reveals that, instead of pulverization, electrochemomechanical stress induces 2 orders of magnitude grain size reduction from a few tens of microns to a few hundred nanometers.
