Here, we developed a dual interface engineering strategy to suppress ion migration in PSMs. Incorporation of Nd₂O₃ on SnO₂ reduces lattice mismatch, reducing residual strain and suppressing ion migration in perovskite films. Meanwhile, a VO_<i>x</i> diffusion barrier layer was employed to mitigate ion diffusion across the electrode interface and prevent electrode corrosion. This combined strategy achieved a high power conversion efficiency (PCE) of 26.22% for small-area PSCs (0.045 cm²) and 89% PCE retention under continuous illumination for 2000 h. Notably, PSM achieved a state-of-the-art efficiency of 22.10%, retaining over 90% of its initial efficiency under continuous illumination for 1600 h. Our work offers an effective strategy to enhance the stability of PSMs and provides deeper insights into the influences of the interface on the ion migration.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"41 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143590012","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}

We present a model of Li plating on a graphite particle coated with a solid electrolyte interphase (SEI) layer to elucidate the coupled effects of ion transport, reaction kinetics, and phase transformation. We derive an analytical expression that relates Li-plating onset time to operating conditions and material properties and introduce a Li-plating diagram. Our framework captures the intricate mechanisms driving Li plating and anode potential drops, extending beyond existing limiting cases of surface ion saturation and electrolyte depletion. By providing an improved understanding of the interrelationships among key parameters, our findings provide valuable guidance for adjusting charging protocols, designing cell components, and engineering artificial SEI layers. Implementing these strategies can help mitigate Li plating and ensure Li-ion battery safety and performance during fast charging.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"37 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143590015","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}

Conventional CO₂ capture methods swing the CO₂ absorption capacity by modulating the temperature or pressure, rendering them energy intensive. Electrochemical CO₂ capture technologies could utilize renewable electricity to modulate the CO₂ absorption capacity electrochemically, enabling viable energetics, capture capacities, modularity, and facile implementation. The electrified route can achieve CO₂ capture from point sources and the atmosphere without requiring heat and pressure. This Review provides an overview of emerging electrochemical pH-mediated CO₂ capture approaches: electrolysis, bipolar membrane electrodialysis and electrodeionization, and proton-coupled electron transfer mediators. It describes the operating principles, materials, components, and system/process configurations, discusses the recent advances, milestones, and remaining challenges, and provides a comparative analysis of capture technologies.

Overview of select applications of variable-temperature electrochemistry. &lt;i&gt;Thermal and Solution Stability.&lt;/i&gt; Identify the temperature range and solvent(s) in which the redox-active analyte of interest is chemically and electrochemically stable. Such evaluations may for example be performed using NMR spectroscopy or UV–visible absorption spectroscopy in conjunction with cyclic voltammetry at varying temperatures in different solvents. &lt;i&gt;Electrochemical Stability.&lt;/i&gt; Assess the stability of different charge states of the redox-active analyte of interest through controlled potential electrolysis experiments over extended periods of time. Such experiments may for example help in identifying phase-change reactions involving precipitation. &lt;i&gt;Kinetic Stability.&lt;/i&gt; Identify the kinetics of chemical and electrochemical reactions associated with the redox system of interest. Assess if the redox-active analyte is resistant to chemical and electrochemical changes over the time course of the electrochemical experiment. Time-dependent electrochemical measurements, including variable-scan-rate cyclic voltammetry and controlled potential/current vs time experiments may inform kinetic stability in the relevant time scale. For instance, the intensity ratios of the anodic and cathodic peak currents in the voltammograms collected at variable scan rates can inform the rate of electron-transfer reactions and help determine any operable kinetic constraints. &lt;i&gt;Chemical Equilibria.&lt;/i&gt; Identify the chemical equilibria that apply to the redox system of interest. Assess whether homogeneous liquid-phase reactions or multiphase processes are involved, and determine if these reactions are sensitive to the solution proton activity. Standard analytical techniques used to study liquids, gases, and solids may be employed for such assessments. Electrochemical measurements in solutions of variable proton activity can shed light on the sensitivity of the given electron-transfer reactions toward protons, as is the case for proton-coupled electron-transfer reactions. Influence of other ions, such as those of the supporting electrolyte, may be investigated in a similar manner. Figure 2.

The Collaborative Innovation Center of Chemistry for Energy Materials (&lt;i&gt;i&lt;/i&gt;ChEM) was approved in October 2014, jointly by Xiamen University (XMU), Fudan University (FDU), the University of Science and Technology of China (USTC), and the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS). The mission of the consortium is to integrate key innovative elements from universities, research institutes, and enterprises both in China and abroad. In addition, &lt;i&gt;i&lt;/i&gt;ChEM leverages the strengths in chemistry and materials sciences of the four member-institutions to further advance cutting-edge energy-related research while also training younger generations for research excellence by strengthening collaboration between the research community and industry. Over the past decade, &lt;i&gt;i&lt;/i&gt;ChEM has focused on common scientific issues in energy chemistry by jointly tackling energy chemistry and energy material systems and introducing a number of core key technologies. Researchers at &lt;i&gt;i&lt;/i&gt;ChEM focus on three main areas: the optimal utilization of carbon resources, chemical energy storage and conversion, and solar energy conversion chemistry. Investigations in these energy-oriented areas use a number of approaches: basic research in synthesis and fabrication, theory and simulation, and instrumentation and methodology. As a result, we are able to make advances in the approaches themselves, as well as in the aforementioned three research areas. To realize the new energy strategic objectives, &lt;i&gt;i&lt;/i&gt;ChEM has adhered to the principle of “chemistry as the foundation, materials as the carrier, and energy as the goal”, addressing critical scientific issues in the development of petroleum alternatives. This approach has led to a series of original results that are both urgently needed by the country and recognized as world-class. In order to celebrate the 10th anniversary of the &lt;i&gt;i&lt;/i&gt;ChEM, The Journal of Physical Chemistry C (JPC C), The Journal of Physical Chemistry Letters (JPCL), and ACS Energy Letters are publishing a joint Special Issue (SI). This SI, organized by the center’s directors, Zhong-Qun Tian (Xiamen Univ.), Dongyuan Zhao (Fudan Univ.), Can Li (DICP, CAS), and Jinlong Yang (USTC), brings together 37 articles on energy materials and chemistry. It is with great pride and reflection that we look back on a decade of groundbreaking research, collaboration, and innovation. &lt;i&gt;i&lt;/i&gt;ChEM has grown into a world-class hub for scientific exploration, fostering multidisciplinary partnerships and pioneering advancements in energy materials chemistry. Since its inception, &lt;i&gt;i&lt;/i&gt;ChEM has been driven by a vision to address the critical challenges facing our world’s energy future.
