Increasing zT is challenging due to the intricate relationships between electrical and thermal transport properties. This study focuses on Y2Te3‐based thermoelectric materials, which are predicted to be promising for high‐temperature applications due to their inherently low lattice thermal conductivity. A series of Y2+xTe3 compositions with excess Y is synthesized to explore the effects on electronic and structural characteristics. Density functional theory calculations suggest that additional Y atoms increase charge carriers, thereby enhancing electrical conductivity and boosting thermoelectric performance. X‐ray diffraction analysis reveals that the presence of excess Y reduces lattice volume and alters bonding structures. Furthermore, the addition of Bi significantly enhances the power factor by promoting the segregation of elemental Bi particles and the formation of Y‐Bi‐rich grain boundaries, which improve weighted mobility. This microstructural optimization leads to a fourfold increase in the Seebeck coefficient, resulting in a peak zT of 1.23 at 973 K and a predicted maximum conversion efficiency of 10.3% under a temperature difference of 673 K. These findings highlight the potential of Y2Te3 for high‐temperature thermoelectric applications and demonstrate the effectiveness of grain boundary engineering in enhancing thermoelectric performance.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"50 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142758363","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 central linking units that connect two acceptor molecules together have a profound impact on dimeric acceptor properties and structure‐performance relationships in blended thin films. It is seen that different linkers significantly affect the electronic properties and morphology in blended thin film. The electron‐donating linker elevates the absorption coefficient, affords a lower bandgap, and reduces energy loss, and thus better photovoltaic device performance. Better fibrillar morphology can be obtained.

In this study, magnesium aluminosilicate (MAS) powder is used to fabricate a mineral‐based colloid electrolyte for Zn//α‐MnO2 batteries. According to theoretical calculations, MAS has a stronger binding energy with Zn2+/Mn2+ ions than with H2O molecules, suggesting the possibility of regulating the solvation structure of Zn2+/Mn2+ ions in a MAS–colloid electrolyte. Based on the experimental results, a high ionic conductivity, wide operating voltage, low activation energy barrier, and stable pH environment is achieved in the MAS–colloid electrolyte. As expected, long‐term cyclic stability can be maintained for 3500 h at 0.2 mA cm−2 in Zn//Zn cells, and high capacities of 255.5 and 239.8 mAh g−1 are retained at 0.2 and 0.5 A g−1 after 100 cycles in Zn//α‐MnO2 batteries, respectively. This performance is attributed to the spatial confinement effect of MAS on the active H2O molecules, which effectively reshapes the solvation structure of Zn2+ ions, guaranteeing reversible zinc deposition, suppressing active manganese dissolution, and ensuring stable interfacial reactions.

However, the practical capacities accesses are severely hindered by unstable electrode/electrolyte interphases (EEI) and irreversible structural degradation, which necessitates efficient additives in electrolyte for generating stable EEI. Herein, a multifunctional additive, 3-Fluoro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)picolinonitrile (FTDP) is proposed to construct robust interfaces at both cathodic and anodic surface, so as to enhance electrochemical performance. FTDP is preferentially decomposed to form B-contained and cyano (CN) group-rich cathode electrolyte interphase (CEI), as well as LiF-, Li3N-rich solid electrolyte interphase (SEI), simultaneously, resulting in the integrity and stability of electrodes. Moreover, the FTDP-derived CEI can suppress transition metal ions dissolution, further facilitating battery cyclability. The multifunctionality of FTDP, including quenching free radicals, alleviating the hydrolysis of LiPF6 and inhibiting HF generation, thus greatly improving interfacial stability.

The porous C4N layer is found to enhance visible‐light absorption ability and facilitate the adsorption and activation of the reactants and intermediates. The hybrid heterojunction follows an S‐scheme charge transfer with the assistance of a strong internal electric field (IEF), which promotes the spatial separation of photogenerated carriers effectively and maintains their strong redox abilities. As a result, the optimized Bi3TiNbO9@C4N unveils a high H2O2 yield rate of 1.25(2) mmol g−1 h−1 in the absence of sacrificial agents and cocatalyst, 10.9 and 3.5 folds higher than those of pristine Bi3TiNbO9 and C4N catalysts, respectively.

Binder engineering is considered a valid strategy to kill two birds with one stone. Herein, sodium lignosulfonate (LS), an important derivative of lignin, is optimized as a neotype binder for the fabrication of an iodine-loading cathode. Owing to the existence of the -SO3Na group, the electrostatic potential of LS molecule contains both negative and positive regions, which prefer to block the polyiodide shuttle behavior through the electrostatic repulsion effect, and adsorb the polyiodides through the electrostatic attraction effect, respectively. Meanwhile, LS molecule holds more negative Gibbs free energies for the consecutive radical reaction, and much stronger adsorption energies for iodine species, manifesting fast iodine conversion reaction kinetics, and effective inhibition for iodine dissolution behavior.

However, the understanding of ASSLBs’ failure remains deficient, thereby considerably hindering their advancement. Herein, the unrecognized failing mode of ASSLBs, voltage noise failure (VNF), characterized by irregular charging voltage configuration, is identified using comprehensive techniques, including laser-induced breakdown spectroscopy. The VNF originates from micro-penetration of Li dendrites, which is demonstrated through direct observation of 3D Li concentration map in CSE. In this phenomenon, the transition metals, dissolved from the cathode, hop to the anode and serve as seeds for dendritic growth in VNF. Inspired by this mechanism and with the aid of DFT calculations, a transition metal scavenging layer is proposed using Prussian blue analogue at the cathode-CSE interface. Consequently, ASSLBs with transition metal scavenging layer exhibit superior capacity (189 mAh g−1 at 0.5 C, NCM811) and stable cyclability (1200 cycles without failure).","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"11 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142758557","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}

These compounds are shown to produce stable PSCs because of their high intrinsic stability. However, the density functional theory (DFT) calculations and X‐ray photoelectron spectroscopy analysis presented here reveal that the presence of Cu in the HTL can weaken the interfacial Pb‐S interactions and compromise the device stability. A clear inverse relationship is observed between the stability of perovskite film and the Cu‐concentration in the HTL underneath. Therefore, to minimize the detrimental effect of Cu, this work explores Cu‐deficient chalcopyrite compounds, CuIn3S5 and Cu(InxGa(1‐x))3S5, as HTLs for PSCs, which results in improved device stability. DFT calculations reveal that incorporating gallium into the HTL reduces the HTL‐perovskite interfacial energy, which results in further enhancement of device stability. The average T80 lifetimes (the time to retain 80% of the initial efficiency) under ambient conditions for the NiO, CuIn3S5, and Cu(In0.3Ga0.7)3S5 HTL‐based devices are 200, 449, and 656 h, respectively.
