More than 50% of Li is currently obtained from Li⁺-rich brine deposits. Also, the LIB manufacturing industry generates wastewater containing Li⁺ mixed with other cations. Thus, the development of methods to selectively extract Li⁺ from various natural and industrial Li⁺-containing solutions are critically needed to ensure a sustainable and environmentally benign Li supply chain. This study reports TiP₂O₇ (TPO) as a promising candidate for selective electrochemical Li⁺ extraction and recovery from solutions containing a mixture of cations where Na⁺, K⁺, Mg²⁺, and Ca²⁺ are more concentrated than Li⁺. In addition, TPO’s ability to extract Li⁺ from a simulated brine mimicking the Uyuni Brine in Bolivia and recovering it as Li₂CO₃ is demonstrated. Its unique advantage over LiFePO₄ and LiMn₂O₄, two candidates previously investigated for selective Li⁺ extraction from brines, is also discussed.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"49 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145078022","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}

Furthermore, traditional PeQDs exhibit obvious luminescence saturation under high light power density excitation. To address these problems, we design and synthesize green-emitting Ce³⁺, K⁺ codoped CsPbBr₃ perovskite microspheres by encapsulating codoped PeQDs in mesoporous silica spheres, demonstrating simultaneous near-unity photoluminescence quantum yields and exceptional overall stability. Green micro-LEDs, prepared by using the PeQD microspheres, achieve an external quantum efficiency of up to 19.54% and a high brightness of 4.26 × 10⁷ cd m^–2.

To overcome this challenge, we report a weakly solvating, all-fluorinated electrolyte designed to mitigate transition metal dissolution. For the first time, the role of electrolyte solvation in suppressing transition metal dissolution is systematically investigated. The tailored electrolyte significantly reduces transition metal dissolution and enhances the electrochemical performance of Li- and Mn-rich (LMR) cathode/graphite cells. This solvation-modulating strategy offers a broadly applicable framework for stabilizing interphases in other earth-abundant cathode chemistries, which similarly demand kinetic protection against interfacial degradation.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"105 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084076","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 unique geometric and electronic structures of SAAs break scaling relationships and enable bifunctional reactivity. Emerging areas such as dual-atom alloys and plasmon-enhanced and electrochemical catalysis are discussed. As the compositional phase space of bimetallic and trimetallic systems grows exponentially, theoretical guidance is essential to navigate this complexity efficiently.

This Perspective revisits the classical Sand’s time model and extends it by coupling electrochemical kinetics and ion diffusion, establishing a unified model for dendrite growth. This framework clarifies the roles of kinetics and diffusion in governing dendrite growth and informs suppression strategies. It also reveals their joint effects in the presence of solid–electrolyte interphases and under varying temperature conditions. By advancing the fundamental understanding of dendrite formation, this work offers guidance for stabilizing metal anodes and enabling reliable metal batteries.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"25 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084077","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}

Review articles on a few popular energy research topics published in 2023–2024 (TENG refers to Tribo Electric Nano Generators, and LEDs refers to Light Emitting Diodes). The legends include the numbers of review articles and the percentages as part of all published peer review articles. Source: Web of Science, Clarivate (retrieved and analyzed on July 7, 2025). <b>Editorial challenges.</b> Whereas scientific articles provide new research advances, review articles are composed based on published literature. As a result, review articles are seldom rejected by journals on scientific grounds after peer review unless they are poorly composed and difficult to comprehend. The number of review articles on a given topic depends on its popularity. For popular topics such as halide perovskites, storage batteries, and LEDs, the number of review articles can reach thousands each year (see Figure 1), making it difficult to assess novelty and impact. Except for a few well-thought-out reviews in each category, others merely serve as placeholders, repeating already summarized content, hoping to get cited. <b>Citation practices.</b> Citing review articles in the introduction of a manuscript is a common practice since the authors do not need to give a full literature survey. Authors often look for the most-cited reviews so their citations remain credible. <i>Just ask any author how many review articles they fully read before citing them in a manuscript.</i> <b>Superficial reviews.</b> The ease of compiling literature through various databases has led to a rise in review articles, sometimes authored by groups who repeatedly publish on trending topics without offering new insights or critical analysis, compiling literature with no specific data analysis, critique, or detailed discussion. Although these articles are likely to be scientifically correct, they are not likely to contribute to the advancement of scientific literature. As authors, we really need to ask ourselves: <i>Is there more room and need for another review on the same popular topic after many similar review papers have been published over the previous years?</i> (2) Just like original research papers, the novelty (timeliness) of a review manuscript could have a significant impact on its significance and usefulness to the research community (<i>i.e</i>., in practical terms, the future citations). The idea of “novelty” of a review has not often been considered when making editorial decisions on accepting a review paper, but now it is becoming important as duplicative articles appear throughout literature. <b>AI-Generated content.</b> The availability of AI tools has made writing even easier.

Using boronic acid (BA)-based SAMs, especially 4-nitrophenyl boronic acid (4-NPBA), the PCE was greatly improved (18.37%). This is attributed to the large molecular dipole moments of the BA-based SAMs significantly increasing the work function (WF) of the FTO, inducing stronger band bending in the perovskite layer. This band bending, whose magnitude is proportional to the difference in the WF between the SAM and the perovskite, facilitated more efficient hole collection. In comparison, MeO-2PACz-based devices yielded only 9.27% and showed an S-shaped current–voltage (<i>I</i>–<i>V</i>) curve, mainly due to the formation of an interfacial energy barrier. Furthermore, the superior performance of the BA-based SAMs even after possessing an interfacial energy barrier can be explained by enhanced hole collection via (i) tunneling aided by short molecular length of BA-based SAMs as calculated by density functional theory (DFT), or (ii) direct hole transfer from perovskite to FTO through the uncovered FTO regions due to lower surface coverage as evidenced by absorption density estimation in X-ray photoelectron spectroscopy (XPS). These findings were further supported by transient absorption (TA) as well as transient photocurrent decay (TPC) analyses, which revealed markedly higher hole extraction rate (3.73 × 10^–3 ps^–1) and lower charge transport time (1.18 μs) when 4-NPBA was used as a SAM layer.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"22 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145071990","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}

Preventing plating requires materials with high-rate capabilities of charge-transfer and ion-transport; however, such materials often suffer from poor thermal or electrochemical stability, resulting in an inherent activity–stability trade-off. This Perspective examines the origins of this dilemma and proposes that temperature─traditionally viewed as a degradation stressor─can be harnessed as a tool. We highlight how asymmetric temperature modulation enables brief high-temperature operation to enhance reaction kinetics while limiting long-term degradation, shifting the paradigm from passive thermal protection to active thermal control. Leveraging this, we propose a thermal–materials synergistic strategy centered on rapid temperature modulation and complemented by materials designed for high-temperature resilience.

However, their performance has lagged behind solution-processed devices. Here, we introduce an in situ phase regulation strategy by co-evaporating a multifunctional ligand, tris(trifluoromethyl)phosphine oxide (TFPPO). The fluorine atoms in TFPPO form hydrogen bonds with the N–H groups of phenylethylammonium (PEA), suppressing the disordered incorporation of PEA and slowing the crystallization of low-n phases. This interaction promotes a more uniform phase distribution and enhances exciton funneling through energy gradients. Besides, the P═O groups of TFPPO could also passivate undercoordinated Pb²⁺ defects. As a result, we achieved a record external quantum efficiency (EQE) of 17.5% among thermally evaporated PeLEDs.
