However, the severe overpotential induced by sluggish redox reaction kinetics significantly hinders their practical application. To address this challenge, photocathodes have been incorporated into LOBs, leveraging photovoltage to compensate for charging voltages and achieve ultralow overpotential. Nevertheless, a comprehensive review of photocathode in LOBs is still lacking. This timely review aims to introduce the pivotal role of photo-assisted strategy in LOBs, and provides an updated overview of photocathode utilized in LOBs. After demonstrating the mechanisms of photo-assisted Li–O2 batteries reaction, research progress for the application of various photocathodes in LOBs is comprehensively reviewed. Special emphasis is placed on the critical correlation between photocathode material design and key challenges in photo-assisted LOBs, including reduced charging potential/improved discharging potential, alleviated electrolyte decomposition, suppressed photogenerated carrier recombination, broadened spectral response ranges, decoupled mass transport and electron transfer, and modulated charge/discharge mechanisms. Finally, future challenges and directions of photocathode material development and application in photo-assisted LOBs systems are reviewed. The current review provides important insight into photo-assisted cathode design as the state-of-the-art strategy for favorable reaction kinetics for high-performance LOBs.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"38 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745396","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 study, an n-type i-TE cell exhibiting substantial negative thermopower and a high output energy density is developed by leveraging the synergistic interplay between thermal diffusion within an ionic hydrogel electrolyte and redox reactions at the electrode interface. Specifically, a gel network featuring dual positive groups is synthesized by cross-linking quaternized chitosan and guanidine molecules via glutaraldehyde, with thermal diffusion further enhanced by incorporating crown ether for complexation. Additionally, NiCo(CO3)(OH)2, a material known for its high hydrophilicity, is utilized as the anode to facilitate rapid ion and electron transfer at the electrode interface. The integration of optimized thermal diffusion within polycationic electrolytes with electrode interface-enhanced ion/electron transport mechanisms significantly improves the sustained output performance and thermoelectric conversion efficiency of the i-TE cell. Notably, the thermopower (Seebeck coefficient) of this n-type i-TE cell achieves a value of −26.04 mV K−1, and its 2 h output energy density reached 1301.61 J m−2 under a temperature difference (ΔT) of 15 K. These findings offer a novel design paradigm for high-performance n-type i-TE cell.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"89 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745395","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 thus obtained cMS-PBI membrane is insoluble in hot phosphoric acid solution (<5% soluble fraction), and is free of the known breaking points under alkaline conditions, i.e., no aromatic ether bonds, no quaternary ammonium groups, no N-alkylated neutral or positively charged imidazole groups. Indeed, a 6 months long alkaline stability test in 2 M KOH at 80 °C shows that cMS-PBI retains its dimensions and its weight without any sign of degradation. The room temperature conductivity increases within the first 24 days, and then remains constant at 192 ± 10 mS cm−1. At 80 °C, the conductivity in 3 M KOH reaches 682 mS cm−1. At 80 °C and with 2 M KOH feed solution, an electrolyzer using robust nickel foam electrodes has a performance of 0.975 A cm−2 at 2 V. With NiFe/Raney nickel, 3.52 A cm−2 (extrapolated) at 2 V are reached. Voltage remained stable in a 200 hours test. In conclusion, it is expected that ion solvating membranes like cMS-PBI can substitute anion exchange membranes in water electrolyzers, and by this improve their lifetime and reduce the cost of green hydrogen.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"103 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745759","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, these model cells are prone to comparability and reproducibility issues. This study examines the extent to which the cathode composite preparation influences the cell performance of a reference system comprising LiNi0.82Mn0.07Co0.11O2 as the cathode active material, Li6PS5Cl as the solid electrolyte, carbon nanofibers as the conductive additive, and an indium–lithium foil anode. The cathode composite is prepared either via hand mortaring or in a mini vibrating mill. The mixing process is found to be critical for the reproducibility of cell performance and accounts for many of the discrepancies observed in the capacities of different cells made with identical materials and following the same cell assembly protocol. The open-circuit relaxation method is implemented to quantify active mass utilization in the cathode in situ, which depends on the mixing process and correlates with the cell performance. This approach allows for a quantitative differentiation between static and kinetic capacity losses during the discussion of specific capacity values. The results demonstrate the significance of cathode composite mixing and the necessity of quantifying the mixing quality for reliable electrochemical data acquisition and interpretation.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"32 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745760","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, a groundbreaking microwave-synthesis strategy is presented that enables the rapid and facile preparation of kilogram-scale ORR/OER electrocatalysts. The unique microwave irradiation generates instantaneous thermal energy, facilitating the formation of nano-carbon bridges that interconnect high-density active sites comprising cobalt single atoms and nanoparticles. This innovative architectural configuration significantly enhances the kinetics of electron/mass transfer and maximizing the accessibility of active sites. The optimized carbon-bridged cobalt catalyst (CBCo-800) demonstrates a commendable half-wave potential (E\u00001/2) of 0.86 V versus RHE and a minimal overpotential difference (ΔE) of 0.696 V. Furthermore, lab-assembled zinc-air battery utilizing CBCo-800 achieved a great specific capacity of 794 mAh g−1 and sustained over 650 h, outperforming commercial Pt/C and RuO2 catalysts. Density functional theory (DFT) calculations elucidate that the nanocarbon bridge between the dual-active sites boosts oxygen activation and optimizes the adsorption/desorption dynamics of *OH/*OOH intermediates, thereby lowering the energy barriers for ORR/OER. This study offers a facile solution for producing dual-active site materials, and also establishes a robust platform for the mass production of high-performance electrocatalysts.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"72 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737272","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}
