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":"10 2","pages":"907–914 907–914"},"PeriodicalIF":19.3,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402469","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 LixAl anode is mitigated in ASSLBs due to the applied external stack pressure, thus preventing the mechanical failure of the LixAl 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. The grain-refined LixAl anode facilitates lithium ion transport, which improves the rate performance and specific capacity of the LixAl anode. Consequently, the assembled single-crystal LiNi0.83Co0.12Mn0.05O2|Li10Si0.3PS6.7Cl1.8|Li0.4Al ASSLBs reach 2000 cycles with a capacity retention of 100% at 3C (13.9 mA/cm2, room temperature), at a high areal capacity of 2.1 mAh/cm2. The all-solid pouch cell with a LixAl anode can reach an energy density of 219 Wh kg–1 based on the total mass of the cell. These results demonstrate the prospect of implementing the Al-based anode in ASSLBs for practical energy storage applications.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"10 2","pages":"898–906 898–906"},"PeriodicalIF":19.3,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143402472","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}

The interlayer generates a LiF-rich solid electrolyte interphase and alloy nanoparticles in contact with lithium to offer active sites guiding lithium nucleation, regulating lithium deposition, and increasing Coulombic efficiencies. With such an interlayer, lithium metal full cells show significantly improved stability compared to those with bare Cu, when paired with a LiFePO4 or LiNi0.8Co0.1Mn0.1O2 cathode.
