However, the ISEs face challenges such as their limited electrochemical stability windows (ESWs) and compatibility issues with high-capacity, high-voltage cathode materials and Na metal anodes. The success of high-performance SSSBs hinges on developing ideal ISEs that deliver high Na+ ion conductivities, robust chemical and electrochemical stability, and well constructed electrode/ISE interfaces. This review explores the fundamental principles and strategies to optimize SSSB performance by addressing issues related to ISEs and their interfaces, emphasizing that many interfacial challenges are intrinsically linked to ISE properties. It highlights recent advancements in ISE research, including the mechanisms of Na-ion conduction and the key factors influencing it, such as crystal structure, lattice dynamics, point defects, and grain boundaries. It also discusses prototyping strategies for cell design from the perspectives of material and defect chemistry. Additionally, the review identifies key challenges and future opportunities for advancing SSSBs and provides rational solutions to guide future research toward the practical realization of high-performance SSSBs.Keywords: Solid-state sodium batteries; Inorganic solid electrolytes; Interfacial mechanism; Electrochemical stability window; Ionic conductivity; Modification strategies","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400612","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further corroborate this, we synthesized a model compound and carry out electrochemical characterization. Quasi-reversible redox behavior, similar to other hydroxybenzene materials, was obtained in an acidic aqueous electrolyte. The four electron exchange was further confirmed by using reduced and oxidized model compounds, which showed comparable electrochemical behavior. Additionally, we prepared insoluble nano sized polymer based on poly(2,3,4,5-tetrahydroxystyrene) which was used as a cathode material in an organic battery. Initial results suggested that these tetrahyroxybenzene polymers are very promising for proton batteries in acidic aqueous electrolytes, whereas their performance in lithium batteries is limited.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400550","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses into the electrochemical integration of cerium with vanadium to enhance traditional redox flow batteries′ energy density and cost-effectiveness. Through an innovative design that allows scalability and addresses the challenges of the lower energy density inherent in vanadium RFBs, V-Ce RFBs demonstrate the potential for more compact and efficient energy storage systems. In this work, we provide the open-source design mono cell for RFBs research. Herein, the research spotlights the electrochemical characterization of Ce-based electrolytes, employing mixed acid electrolytes to improve solubility. For improving the electrochemical performance of the V-Ce RFBs including the diffusion coefficients and electron transfer rates, L–Leucine and L–Lysine have been used as organic additives. Obtained results have revealed that these additives not only influence the electrochemical stability and efficiency but also significantly affect to the charge-discharge properties of the V-Ce RFBs, in which, the L-leucine showing superior performance over L-lysine. These findings propose a new way for optimizing the stability of V-Ce RFBs for large-scale energy storage regarding efficiency, safety, and environmental impact.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400551","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143119603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All electrochemical measurements were performed in phosphate-buffered saline aqueous solution (pH 7.4) at room temperature (25 °C) and body temperature (37 °C). The results of the work confirmed that the modification of the carbon or metallic electrode with conducting polymer PEDOT : PSS significantly reduced the interfacial impedance and improved charge storage capacity and current injection limit due to its high electroactive surface area, roughness and porosity compared to the bare substrates. The work showed that solution temperature is a critical factor that can influence the electrical interface parameters of electrodes for neural stimulation. Understanding and controlling these temperature-dependent effects are essential for ensuring the reliability, safety, and efficacy of neural stimulation applications in both research and clinical settings.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 2","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400459","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, issues still to be solved for practical use include the improvement of Faradaic efficiency (FE) towards C2H4, electrode durability, and suppression of competitive hydrogen evolution reaction (HER). In this work, hydrophobic polymer, polytetrafluoroethylene (PTFE), added porous Cu electrocatalysts were firstly and successfully prepared on gas diffusion layer, and the significant enhancement of FEs toward C2+ products, especially C2H4, and durability were found. CO2RR test in flow cell as a gas diffusion electrode (GDE) revealed that the GDE with porous Cu electrocatalysts showed higher FE(C2H4) to FE(CO) while significant HER and instability issues remained. Further modification by PTFE to form porous Cu-PTFE hybrid structure significantly decreased FE(H2) to 11.6 % in minimum, enhanced FE(C2H4) to 51.1 % in maximum and raised durable CO2RR for over 24 hours under current density of −300 mA cm−2. PTFE addition should form a secured pathway for gas species, including both reactant and product which was beneficial for durable and selective C2H4 production.
