However, the increasing demand for LIBs, coupled with problems related to availability and lack of manufacturing centers, has led to lithium market inflation. At this point, sodium-ion batteries (SIB) represent an economically and environmentally attractive alternative for LIBs. Prussian Blue cathodes (PB) have been extensively studied as cost-effective materials with volumetric variations that allow the accommodation of sodium ions in the structure. Herein, we present a quasi-solid Na-ion cell based on PB cathode and green gel polymer electrolyte (GPE). Nanometric and micrometric PB powders are synthesized and characterized using a wide variety of structural, compositional and electrochemical techniques. The effect of the PB particle size in combination with different electrolytes is investigated. Enhanced cell safety is obtained using a GPE prepared by following a novel green method that avoids using toxic organic solvents. All the tested cells report remarkable electrochemical performance, being the nanometric-PB/ GPE/ Na cell configuration the one with the highest specific capacity and almost no capacity loss after 100 cycles, outperforming analogous cells assembled with liquid electrolyte. This electrochemical stability is triggered by a robust electrode-electrolyte interphase.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 4","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400350","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431568","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}

In this work, sawdust from the processing of birch logs was used to produce a highly porous carbon material (CBW) that is employed for the construction of electrodes for aluminum batteries (ABs) and supercapacitors (SCs). A multitude of characterizations indicated that CBW is built in with highly disordered amorphous carbons and an extremely high specific surface area of 3029 m2 g−1 which is predominant with microporous features. The chemical analysis of CBW indicated the presence of a significant amount of oxygen functionalities. As a cathode of AB, CBW achieved discharge capacities 115, 74, 54, 50, 47, 43, and 29 mAh g−1 at current rates 0.1, 1.0, 2.0, 3.0, 4.0, 5.0, and 10.0 A g−1, respectively. Similarly, SC with CBW symmetric electrodes exhibited capacitances 143, 94, 87, 79, 74, 69, 65, and 51 F g−1 at current rates 0.1, 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, and 10.0 A g−1, respectively. The electrochemical characterization revealed that CBW is promising for ABs and SCs, and controlling the porosity type could further enhance the performance.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 4","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400549","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431119","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, 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}

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.

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.
