The high OER overpotentials would originate from the high electron transfer barriers in the electrolyte/catalytic layer/catalyst core interfaces during the water oxidation reactions. Here, we assemble the temperature-dependent magnetic YFe1-xMnxO3 core and the paramagnetic YFeOOH shell to form a YFe1-xMnxO3@YFeOOH core-shell structured catalyst to explore the effects of thermal-stimulated magnetic state of catalytic materials on OER kinetics. We find that the thermal-stimulated paramagnetic state of YFe1-xMnxO3 core contributes to the accelerated electron transfer at the YFe1-xMnxO3@YFeOOH core-catalytic layer interface. Meanwhile, it improves the intrinsic OER activities of the YFeOOH catalytic layer. The thermal-stimulated magnetic transition of YFe1-xMnxO3 (from antiferromagnetic to paramagnetic) enlarges the magnetic disorder at the YFe1-xMnxO3@YFeOOH interface to reduce the spin flipping barriers and induces to produce the highly OER-active electronic states for YFeOOH catalytic layer due to the strong interactions between YFe1-xMnxO3 core and YFeOOH catalytic layer, thus breaking the linear Arrhenius relationship. Our findings provide a new low-barrier OER route by thermal-stimulated magnetic disordering.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"27 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142777092","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}

Herein, we demonstrated the in-situ anchoring of indium clusters on carbon matrix with iron-nitrogen-carbon sites via the pyrolysis of supermolecule aggregation coordinated with indium and iron ions, aimed to prepare advanced bifunctional electrocatalysts for ORR and OER. With the detailed atomic structure analysis, the modulation on coordination environment between indium cluster and iron-nitrogen-carbon sites induces asymmetrical charge distribution to reduce the reaction barrier via the the p-d orbital hybridization, thus achieving superior bifunctional electrocatalytic activity. Consequently, the rechargeable ZABs demonstrated a cycling durability of 1650 h. Moreover, the solid-state batteries also exhibited a large power density of 220.0 mWcm-2.

However, they are prone to surface corrosion and uncontrolled dendrite growth on zinc anode, particularly under high current densities. Herein, we propose an artificial solid electrolyte interphase (SEI) composed of complex Zn2+ salts to alter the de-solvation process and homogenize the electric field, thereby enabling stable circulation of AZIBs. This SEI is formed through the excitation of iminodiacetonitrile (IDAN) into Iminodiacetic acid (IDA) on the surface of the zinc anode during electroplating. Simultaneously, the generated IDAs conjugate with flowing zinc ions thus creating a dense protective layer embedded into the anode surface. The obtained SEI exhibits superior Zn2+ conductivity, super-hydrophilic property, electrical insulation and negligible interfacial resistance, imparting outstanding durability to the zinc anode even at an ultra-high current density (100 mA·cm-2, over 630 h) without dendrite growth, giving a cumulative plating capacity exceeding 31.5 Ah·cm−2. Moreover, the favorable zinc plating/stripping behavior facilitated by the SEI enables stable operation under harsh conditions (90% depth of discharge, 440 h of Zn||Zn and 20 A g-1, 2000 cycles of Zn||NH4V4O10). The current density tolerance provided by the complex SEI, achieved through a novel in-situ excitation/conjugation fabrication process, promises to enrich SEI strategies and expand the application of AZIBs, particularly in fast-charging/discharging battery systems.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"12 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142763154","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 addition, the roles played by excitations delocalized over two or more (macro)molecules and by localized triplet states remain to be well-defined. To address these issues, we have combined molecular dynamics simulations with density functional theory calculations to provide a comprehensive analysis of charge generation and charge recombination in the representative PM6:Y6 blend, describe loss mechanisms, and assess the influence of disorder on the electronic processes. The results allowed the identification of Y6 excimer-like states that can efficiently dissociate into states with hole-electron separation distances larger than those in conventional donor:acceptor interfacial charge-transfer states. They also point to the appearance of low-energy defect states upon formation of Y6 twisted conformations, which can negatively impact the Y6 chemical stability and device performance. Importantly, it is found that the local triplet states formed via non-geminate recombination can efficiently transfer back to triplet CT states, opening the way to eventual dissociation into free charges. Overall, our work provides valuable insight into the charge dynamics within PM6:Y6 active layers.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"7 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142763156","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}

A series of solid-state electrolytes (SSEs), regarded as an essential component of ASSSMBs, have been extensively developed in recent years. Among them, the Na superionic conductor (NASICON)-structure Na1+xZr2SixP3-xO12 (0≤x≤3, defined as NZSP) materials have attracted overwhelming attention as the most appropriate SSEs for the next-generation high energy density ASSSMBs. Herein, this review seeks to provide a comprehensive and in-depth understanding of NZSP SSEs, starting by investigating their fundamentals, including composition, crystal structure, Na+-ion conduction mechanism, synthetic methods, and the key challenges associated with the NZSP-based ASSSMBs. Subsequently, comprehensive constructive modification strategies are proposed to optimize integrated NZSP SSEs-based ASSSMBs. Finally, informed and strategic perspectives from various angles are summarized, providing potential guidance and possible avenues for further research aimed at achieving exceptional NZSP SSEs-based ASSSMBs for practical applications.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"214 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142763155","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 energy contribution of Te0/Te4+ is only one-third of the total redox-amphoteric conversion, which entails the contribution maximization for energy upgradation. The underlying kinetics-limited factor is vital but usually overlooked in previous explorations. Herein, we unlock a halogen-bond chemistry-rectified Te0/Te4+ redox with an almost maximized contribution for 700-Wh kgTe-1 Zn batteries. The Zn-X bond barriers in ZnX42- (X = Cl, Br) species from ILEs play crucial roles in rectifying the Te0/Te4+ redox kinetics, especially in localized concentrated ILEs, resulting in sharply different redox conversion depth. When the ZnBr42- with weak Zn-Br bond (34.96 kcal mol-1) as the activator, the Te0/Te4+ redox contribution can be maximized to ~90.0% over 5000 cycles at 5 A g-1, 1.8-fold higher than that with ZnCl42- activator via strong Zn-Cl bond (102.81 kcal mol-1), surpassing those in most aqueous systems (ca. 33.0%).

However, fulfilling continuous energy output is still challenging because of the non-reciprocating motion of cations and anions during diffusion by adopting a steady heat source. Herein, we propose a moderate-concentration phase-change electrolyte for tuning the thermodiffusion process and the thermopower. Interestingly, the dominant ion can be alternated between cations and anions only by operando regulation of the physical state of the as-designed electrolyte, enabling the reversible polarization of devices from the p-type to the n-type with a tunable thermopower from 3.2 to −2.1 mV K−1. Moreover, the correlation of phase transition behaviors, solvation structures, and thermoelectrochemical performances is investigated. As a proof-of-concept, a prototype module consisting of n-type and p-type units connected in series displays high sensitivity and stability for long-term power generation under light irradiation, demonstrating the potential of phase-change electrolytes in energy-related applications.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"75 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142760137","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}
