Despite rapid progress, defect-induced nonradiative recombination remains a major obstacle, hindering further improvements in device efficiency and operational stability. In this work, we introduce 1H-indole-3-carbohydrazide (1H-CBH) as a multifunctional molecular additive that effectively mitigates these issues through synergistic defect passivation. Specifically, 1H-CBH simultaneously coordinates with undercoordinated Pb2+ ions and forms hydrogen bonds with uncoordinated I- ions and formamidinium (FA+) cations. This dual interaction strategy promotes larger grain growth, reduces grain boundary defect density, and enhances interfacial compatibility with the electron-transport layer (ETL), thereby enabling improved charge transport. As a result, the incorporation of 1H-CBH into mixed-cation PSCs yields a remarkable enhancement in power conversion efficiency (PCE) from 21.18% to 23.59%. Moreover, the 1H-CBH-modified devices demonstrated exceptional environmental stability, retaining their initial morphology after 8 months under ambient conditions (25 ℃, 50-80% relative humidity), whereas unpassivated counterparts underwent complete degradation. Under inert N2 atmosphere, PSCs incorporating 1H-CBH maintained >80% of their initial PCE after 600 h continuous storage. These results highlight the critical role of multifunctional additive engineering in achieving highly efficient and durable perovskite solar cells, paving the way toward scalable and reliable photovoltaic technologies.","PeriodicalId":492045,"journal":{"name":"Energy Materials and Devices","volume":"4 1","pages":"9370088-9370088"},"PeriodicalIF":0.0,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/EMD.2026.9370088.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strategic incorporation of trace Ru species (~ 2 wt.%) induces favorable electronic modulation at the heterointerface, optimizing the adsorption energetics of oxygen-containing intermediates. The resulting Ru@NiFeB electrode exhibits exceptional OER performance with an overpotential of merely 235 mV at 100 mA/cm2 in 1 M KOH, outperforming commercial RuO2 catalysts. Remarkably, the electrode sustains 1000 mA/cm2 for over 150 hours in concentrated 4 M KOH electrolyte without discernible degradation, representing one of the most stable low-doped noble metal-based OER catalysts reported to date.

However, their progress is plagued by sluggish ion-transport kinetics, which lead to inferior rate capability. Herein, oxygen defects and vertically aligned porous nanosheet architecture were engineered in VN/carbon fiber (VN/CF) cathode to overcome these issues. This structure was realized via the initial growth of vertically aligned V2O5 nanosheet templates on gas-spun carbon fibers, followed by high-temperature NH3 treatment. The oxygen defects accelerate bulk diffusion kinetics within VN. Meanwhile, the vertically aligned VN nanosheet array possess lower charge-transfer resistances, enhancing surface diffusion kinetics. These features synergistically improve overall Zn2+ transport and thereby endow high-rate performance. Consequently, the free-standing VN/CF cathode exhibits exceptional rate performance, delivering a capacity of 263.4 mAh g-1 even at a high current density of 10 A g-1. When assembled into flexible AZIBs, the device exhibits a high-rate capability of 249.7 mAh g-1 at 10 A g-1 and stable performance even under various bending deformations, demonstrating significant potential for next-generation wearable devices.","PeriodicalId":492045,"journal":{"name":"Energy Materials and Devices","volume":"4 1","pages":"9370086-9370086"},"PeriodicalIF":0.0,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/EMD.2026.9370086.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147915375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, challenges such as dendrite formation, hydrogen evolution reactions (HER), and corrosive passivation on the zinc metal surface impede their commercial viability. To tackle these issues, we have developed hollow nanotubular magnesium silicate interfacial layer on the zinc metal anode (Zn@MgSi). This unique layer structure and the negatively charged surface of MgSi strips H₂O molecules from [Zn(H₂O)₆]²⁺ to facilitate the desolvation process. Zn²⁺ is temporarily immobilized at the MgSi sites to avoid random diffusion. The electric field guides the uniform distribution of Zn²⁺ and the ion channel guarantees rapid transport. Ultimately, the Zn²⁺ flux is co-regulated to achieve dendrite-free deposition. Consequently, the Zn@MgSi symmetric cell exhibits enhanced zinc ion transfer number (0.64), improved performance, and the lifespan exceeding 1600 h at 1 mA cm⁻². It also demonstrates robust cycling stability, operating for 200 h at higher current densities (5 mA cm⁻²). Zinc-ion hybrid capacitors assembled with Zn@MgSi electrodes achieve high cycling stability with over 5000 cycles. This study underscores the effectiveness of the artificial interfacial layer strategy in stabilizing zinc metal anodes, providing fundamental understanding for the development of advanced aqueous zinc-ion hybrid capacitors.","PeriodicalId":492045,"journal":{"name":"Energy Materials and Devices","volume":"3 4","pages":"9370073-9370073"},"PeriodicalIF":0.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sciopen.com/article_pdf/1947095334053814273.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147899869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their low ionic conductivity and ion transference number frustrate the application in solid state batteries due to the low mobile Li+. Herein, we construct a bimetallic zeolitic imidazolate frameworks coupled amorphous titanium oxide (TiO2@Zn/Co-ZIF) heterojunction nanoparticle as filler to form composite solid-state electrolyte (PVZT). The amorphous TiO2 layer on filler can effectively facilitate the dissociation of salt by Lewis acid-base interaction with Li salt anion. The Zn/Co-ZIF not only provides extra selective ion pathway for Li+ transport, but also sieves anion by limited pore sizes. The synergistic effect contributes to the high room temperature ionic conductivity (8.8×10−4 S cm−1) and ion transference number (0.47) of PVZT. The symmetrical battery using PVZT exhibits steady Li+ deposition/stripping more than 1100 h at charge/discharge of 0.1 mA cm−2. The LiNi0.8Co0.1Mn0.1O2/Li full battery using PVZT retains 75.0% of capacity after 1200 cycles at 2C.
