This configuration influences reaction efficiency by altering the spin states of intermediates. Thus, identifying the surface spin configuration is essential for understanding the mechanisms affecting catalytic activity. This work designs multidomain and single-domain Fe7S8 nanosheets through thickness control. Under a 200 mT magnetic field, the multidomain sample transitions to a single-domain state, while the surface spin configuration of the single-domain sample remains unchanged, as observed via magnetic force microscopy. Electrochemical tests show that a saturated magnetic field of 200 mT reduces the overpotential of the multidomain sample from 306 to 240 mV at 10 mA cm–2, while the single-domain sample maintains an overpotential of 257 mV. These results demonstrate that spin disorder at magnetic domain walls limits spin selectivity during the OER, suggesting strategies for developing innovative spin-selective catalysts.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"14 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030883","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}

Among these, the p-BM material exhibits high energetic ordering in film, appropriate energy levels, and efficient carrier extraction, enabling PSCs to achieve power conversion efficiencies (PCEs) of 25.5% and 24.03% for aperture areas of 0.0625 and 1 cm2, respectively. Additionally, a perovskite solar mini-module (size 16 cm2) based on p-BM HTM achieved a PCE of 22.4%.

The application of thermoelectric technology is closely related to materials’ thermoelectric and mechanical properties. However, the strong coupling of key parameters involving charge carriers and phonon transport hinders the substantial improvements in overall thermoelectric performance. In recent years, a high-entropy strategy promoted remarkable progress in the field of thermoelectric materials by leveraging the four core effects. In this review, we first discuss the theoretical basis for how a high-entropy strategy synergistically optimizes thermoelectric performance. We then classify the examples where high-entropy effects can optimize electrical, thermal, and mechanical properties in thermoelectric materials. Following this, we summarize the overall advances that the high-entropy strategy has brought to thermoelectric materials and devices. Finally, we point out the remaining challenges in high-entropy thermoelectrics and offer perspectives on future research directions in this field.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"82 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019994","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":"49 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143019996","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}

This study introduces a strategic approach to improving LMB cycle stability by optimizing charge/discharge rates. Our results show that slow charging (0.2C) and fast discharging (3C) significantly improve performance, with a multilayer LMB retaining over 80% capacity after 1000 cycles. Fast discharge rates promote lithium plating beneath the SEI layer, suppressing its growth and improving Coulombic efficiency, whereas slow discharge rates facilitate lithium plating above the SEI, leading to SEI accumulation. We propose a rational hypothesis linking SEI conductivity and cycling conditions and introduce an intermittent pulse discharge protocol to emulate electric vehicle applications, further improving the stability. These optimized cycling strategies enhance the LMB lifespan, utility, and safety, paving the way for broader market adoption in the years ahead.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"33 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992560","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 proposed data-driven framework identifies the salient regions in the time-resolved multivariable data and helps to uncover underlying thermodynamic/kinetic aging mechanisms. We also demonstrate the incorporated thermal information obtained via optical fibers complements voltage signals by improving prediction accuracy and antinoise ability.
