In addition to this, electron injection along with self-assembly of the dyes also plays a rather important role, and therefore their precise control is highly desirable and challenging too. This study deals with the molecular engineering approaches directed toward the molecular design and synthesis of two unsymmetrical squaraine dyes (SQ-260 and SQ-261), introducing extended π-conjugated moieties in the dye molecular framework of the reference dye SQ-258. Further, the bifacial DSSCs were fabricated using the dyes, and their photophysical and photovoltaic properties were investigated comprehensively. SQ-258, bearing a typical unsymmetrical squaraine dye structure, exhibited higher dye aggregation, a lower energy barrier for dye regeneration, and a relatively narrow photon harvesting window. SQ-260, possessing a cyanoacrylic acid moiety as its anchoring group, solved the problem of lower electron injection, but it exhibited higher aggregation. Finally, SQ-261 was logically designed by incorporating a 1,3-indandione moiety in the central squaric acid core and a cyanoacrylic acid anchoring group in the terminal indole ring, thereby allowing the simultaneous control of aggregation, greater electron injection, and wide-wavelength photon harvesting. However, SQ-261 displayed a lower power conversion efficiency (PCE), mainly due to a very low driving force for electron injection (0.17 eV). This lower driving force has been attributed to the lower band gap (Eg) of SQ-261, which is a consequence of its highly red-shifted absorption edge.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":"7 24","pages":"12004–12015 12004–12015"},"PeriodicalIF":5.4,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsaem.4c02497","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Toward these potential applications, the development of water-stable CP glasses is crucial to maintaining stable power generation over the long-term. Here, we report a water-stable Al(III)-based CP glass ((dema)0.9[Al(H2O)1.8(H2PO4)3.9(H3PO4)1.1]). Compared to previously reported Zn-based CP glasses, the Al-based CP glass showed significantly higher hydrolytic stability due to stable coordination bonds. In addition to improved water stability, the Al-based CP glass exhibited high viscosity (η = 101–104 Pa·s) and high ionic conductivity (>20 mS·cm–1 at 120 °C) under anhydrous conditions. This unique property is attributed to a Grotthuss-type selective proton transport mechanism. The H2/O2 fuel cell power generation using this CP glass exhibited a high maximum power density (299 mW·cm–2) and high open-circuit voltage (0.93 V) under anhydrous conditions at 120 °C. These results demonstrate that the employment of Al(III) in CP glasses is a promising strategy for the practical application of CP glasses in fuel cell devices.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":"7 24","pages":"11937–11945 11937–11945"},"PeriodicalIF":5.4,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on density functional theory (DFT) calculations, it was found that the N3Zn-CuN4-DOPL catalyst target-modified with 2,5-dioxopyrrole significantly reduces the energy barrier of the CH3–H bond activation (0.69–0.34 eV), facilitating the oxidation of methane to methanol. The electronic properties calculations revealed that the Cu atom acts similar as electron reservoir and electron channel, and the existence of a strong σ-bond between the Cu atom and the N4 atom can substantially increase the amount of electron loss from the Cu atom, thus promoting the oxidation of methane to methanol. The special electronic phenomenon that N3Zn-CuN4-DOPL promotes the CH3–H bond activation was named as the “bowstring-release effect.” That is, the Cu atom connected to the O* is equivalent to pulling the bowstring; the Cu atom releases the O*, which is equivalent to loosening the bowstring. This study provides useful guidance for regulating the catalytic activity by targeted modification of the main catalytic site of dual-atom catalysts.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":"7 24","pages":"11733–11740 11733–11740"},"PeriodicalIF":5.4,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 practical applications of LMBs are hindered by short cycle life and safety concerns, mainly associated with the side reactions between Li metal anode and liquid electrolyte and the growth of Li dendrites during cycling. In this study, we develop a stable artificial solid electrolyte interphase (aSEI) layer, which consists of a surface-treated (ST) PEO–Li6.4Ga0.2La3Zr2O12 composite polymer coating layer (CPL) on a Li metal anode. The developed aSEI is stable against a selected electrolyte and enables a uniform electrodeposition of Li. Therefore, STCPL@Li||LiNi0.8Mn0.1Co0.1O2 (NMC811) cells exhibit improved cycling stability compared with bare Li||NMC811 cells at moderate to high current densities. Notably, using a 50 μm-thick Li and a practical NMC811 cathode (∼4.8 mAh cm–2), a capacity retention of 85% is obtained for STCPL@Li||NMC811 cells at a current density of 2.4 mA cm–2 after 300 cycles compared with 24% for bare Li||NMC811 cells. Furthermore, STCPL@Li||NMC811 cells demonstrate higher capacities at charge current densities of 2.4, 4.8, and 7.2 mA cm–2 compared with bare Li||NMC811 cells. These findings suggest that STCPL is promising for high current density practical LMBs.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":"7 24","pages":"12084–12091 12084–12091"},"PeriodicalIF":5.4,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 study, to obtain a deeper understanding of the correlation between electrolyte composition and physicochemical properties, the anionic effects in binary mixtures of various Li salts and 3-methylsulfolane (MSL) were systematically studied. The ionic conductivity of the Li salt/MSL mixtures increased as the Lewis basicity of the anions becomes weaker. In HCEs with a molar ratio of Li salt/MSL = 1/4, the fraction of free MSL decreased as the Lewis basicity of the anions weakened, leading to a higher activity of Li+. The Li ion transference number in the HCEs decreased with weakening of the Lewis basicity of the anion. Electrochemical impedance measurements revealed that the charge-transfer kinetics of the LiCoO2 and Li metal electrodes in the HCEs were enhanced using weaker Lewis basic anions. Our findings reveal that the utilization of Li salts with weak Lewis basic anions is essential for enhancing the power density of lithium batteries with HCEs. This work provides insights into the functions of anions in sulfone-based HCEs and the correlation between the HCE composition and battery performance, which may be helpful for the design of electrolytes of advanced lithium batteries.","PeriodicalId":4,"journal":{"name":"ACS Applied Energy Materials","volume":"7 24","pages":"11799–11806 11799–11806"},"PeriodicalIF":5.4,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The device achieves an output voltage of 97.3 ± 2.4 V and 19.6 ± 1.1 μA with a power of 396.4 ± 23.2 μW (density 33.0 μW/cm2), exceeding the performance of previously reported single-component nanofiber acoustoelectric devices.
