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}

Nevertheless, DSSCs will require further development in manufacturing methods and materials to remain competitive with other thin-film solar technologies that offer high photovoltaic efficiency. It is essential to give an overview of the latest developments in this area and highlight the primary elements required for realizing high-performance technologies, such as photoanode modification, dye formulation, and electrolyte optimization. Recent advancements have shown promising improvements in DSSCs with copper-based electrolytes, and integrating new interface materials like preadsorbents or postadsorbents has also opened new possibilities for DSSCs.

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}

However, existing methods for evaluating retired batteries are time- and resource-consuming, hindering efficient screening for later recycling or reuse. Herein, combining optical fiber sensors and interpretable machine learning (ML), we establish a data-driven framework for retired battery datasets with 265 cells of different chemistries (LiFePO4/graphite, LiMn2O4/graphite) and achieve ultrafast state of health diagnosis within 3 min, offering mean absolute errors of 1.17% and 2.78%, respectively. 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. This work not only showcases the potential of battery sensing in retired battery diagnosis but also unlocks the unexplored synergy between sensing and interpretable ML for diverse battery applications.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"71 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142990757","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, these advanced BPMs have only been demonstrated in BPM water electrolysis (BPMWE) configurations where the BPM is under static compression by the porous-transport layers. It is important to study these BPMs in applications like electrodialysis where large degrees of static compression are not possible. We present a BPM electrodialysis (BPMED) platform to measure water-dissociation overpotential (ηwd) and compare BPMWE and BPMED systems. We show advanced BPMs with half the ηwd compared to commercial BPMs for BPMED while maintaining ∼90% current efficiency from 0.05–0.5 A cm–2. The BPMED ηwd values are, however, about 0.2 V higher at 0.5 A cm–2 than those for BPMWE.

Herein, a bottom-up cocrystallization strategy, involving in situ transformation of amorphous Ni–P through gas–solid reactions, is proposed to synthesize a series of nickel-based heterojunctions on carbon cloth (CC). Thereinto, interface-wealthy NiS2-Ni2P/CC with densely packed 3–4 nm crystallites demonstrates superb catalytic performance for both hydrogen and oxygen evolution. The electrolyzer merely requires cell voltages of 1.79 and 1.89 V to propel overall water splitting currents of 200 and 400 mA cm–2, respectively, outperforming the vast majority of reported nickel-based heterojunctions. Theoretical calculations reveal that charge redistribution and electronic structure modulation optimize the hydrogen and oxygen evolution pathways at the NiS2 and Ni2P sides of the interfaces, respectively. Moreover, uniform hybridization with densely distributed heterointerfaces offers abundant active sites for electrocatalysis, pioneering an extendable approach for constructing advanced heterojunction catalysts for green hydrogen production.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"27 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142989008","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}
