The mechanism of how the electronic structure of substitution ions impacts the phase structure and properties of SrCoO3−δ was in-depth elucidated, overcoming the inherent trade-off between specific capacity and cycle stability in perovskite materials. The as-prepared SrCo0.925Sc0.075O3−δ electrode achieves a high capacity of 467.7 C g–1 (129.92 mAh g–1) at 1 A g–1, with retention of 97.4% of its initial capacity after 10,000 cycles. Inspired by canopy structures, a “branch”-like dual-network 3D gel system was created and in situ integrated with the electrode as the “trunk”. This unique structure offers robust mechanical strength and flame retardancy, establishing an efficient conductive network. Devices featuring this design show electrochemical stability and flexibility, ensuring safe operation at extreme temperatures while balancing the stability and energy density. This research opens avenues for high-performance supercapacitors and quasi-solid-state gel batteries tailored applications.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"7 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619053","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}

Pivoting from the prevailing approaches that focus on electrode active materials and electrolytes, herein, we introduce a class of S electrode binders based on soft acidic–hard basic (SAHB) ionomers. The SAHB binder contains a soft cation (tetraallyl ammonium ion, TA+) paired with a hard counteranion (nitrate, NO3–), allowing matched interactions with Li polysulfides (LiPS) via soft acid–soft base (TA+–Sx2–) and hard base–hard acid (NO3––Li+) pairings. This intermolecular coupling retards LiPS diffusion, promoting three-dimensional granular Li sulfide (Li2S) growth, guided by a high Damköhler number (Da). Consequently, the SAHB binder enables a Li–S cell to achieve a high specific capacity of 1545 mAh gsulfur–1 (corresponding to 92.3% S utilization) and stable capacity retention (71.5% after 300 cycles at a current density of 1 C), outperforming previously reported S electrode binders.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"42 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619056","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}

Electrochemical and material analyses show that the thickness and heterogeneity of the SnO2 layer are the primary factors governing ionic transport in the SnO2 WD catalyst layer and influencing WD performance. At optimal deposition conditions, the SnO2-catalyzed BPM electrolyzer has a low total cell voltage at 1 A cm–2 of 1.93 V and a WD overpotential (ηwd) of 41 ± 7 mV.

However, hydrogen precipitation, byproduct aggregation, and dendrite growth at zinc anode as well as material degradation of the cathode severely impede further practical development. Here, we construct organic–inorganic hybrid interfacial films on electrodes by employing trifluoroacetamide (CNF) as an additive. The interfacial films homogenize zinc deposition, inhibit the byproducts’ aggregation as well as hydrogen evolution on the anode, and enhance cathode morphological integrity upon cycling. The cycle life of Zn||Zn cells is significantly extended at a high current density. Meanwhile, a Coulombic efficiency of 99.9% is achieved at 10 mA cm–2 after 4000 cycles for Zn||Cu cell. The Zn||Na2V6O16·3H2O full cells after 12000 cycles present 145 and 99 mAh g–1 at 5 and 20 A g–1, respectively. Therefore, the efficient and convenient strategy of introducing an electrolyte additive provides a reliable solution to issues at the interfaces for other secondary battery systems.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"17 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608361","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}

In this work, we have screened the surface passivation of CsPbCl3 NCs using ligands with different functional groups (amine, sulfonic, and phosphonic acid) and metal halides (mono- and bivalent) with the aim of improving the emission yield and stability of CsPbCl3 NCs. This enabled us to find that phosphonic acids are the ligands that showed the highest efficiency as they occupy Cl vacancies and covalently bind to the Pb on the surface of NCs, together with the incorporation of bivalent metal chlorides that showed substantial enhancements in PLQY. Consequently, the most effective passivators were those that passivate Cl vacancies, indicating these to be among the most detrimental traps. This is further validated through Density Functional Theory (DFT), suggesting that the trend in adsorption energies is as follows: hexylphosphonic < hexylsulfonic < oleylamine < tetrabutyl ammonium, which is also coherent with the charge transfer mechanism and corresponding electronic structure of the halide perovskite surface with the ligands. Furthermore, after evaluating different passivation strategies, we identified in situ passivation as the most effective method for obtaining highly luminescent CsPbCl3 NCs that exhibit stability for over 6 months. Thus, this work is expected to guide the perovskite NC researchers to choose effective passivating agents and passivation strategies toward bright blue luminescent colloidal halide perovskites and beyond.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"21 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143599557","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, the elimination of cobalt in layered oxides generally results in a significant decrease in capacity and/or a compromised cycle stability. Herein, we show that these intertwined issues of the cobaltless systems can be remedied by meticulously tailoring inherent defects induced at multiscale. It is demonstrated that a simple excess incorporation of lithium in the structure can effectively reduce the cation disorder and unexpectedly alter the microstructure forming routes, thereby enhancing electro-chemo-mechanical stabilities of layered cathodes. Our investigations reveal that this surplus lithium facilitates topotactic lithiation of precursors during calcination, rendering mechanically robust particles with fewer nanoporous defects and reduced cation disorder. Defect-regulated cobalt-free layered oxides successfully deliver a reversible capacity of 189 mAh g–1 at 0.5C with a retention of ∼85% after 300 cycles under commercial-level electrode loading.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"54 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143599562","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}
