The objective is to develop a highest proton-conducting bio-membranes using Peltophorum pterocarpum (PP) incorporated with ammonium nitrate (NH4NO3). Addition of 0.5 ml GQD with the highest ion-conducting membrane resulted with better ionic conductivity values. All prepared bio-membranes with ammonium nitrate have been characterised by various characterisation techniques XRD, DSC, AC impedance, LSV, and transference number measurement. The amorphous/crystalline nature of prepared bio-membranes has been analysed by using XRD. The glass transition (Tg) temperature of the bio-membranes has been obtained by using DSC analysis. By using AC impedance analysis, the highest proton-conductivity of 6.91 × 10−4 has been obtained for the composition of 1 g PP with 0.7 NH4NO3. The improved ionic conductivity value of 3.83 × 10−3 has been obtained due to the addition of 0.5 ml GQD with 1 g PP with 0.7 NH4NO3. The electrochemical stability window of 3.1 V for (1 g PP with 0.7 NH4NO3) and 3.5 V for (1 g PP with 0.7 NH4NO3 + 0.5 ml GQD) have been found using linear sweep voltammetry. Transference number measurement has been done by using Wagner’s polarisation. The highest proton-conducting bio-membrane and highest conducting membrane with 0.5 ml GQD has been utilised to fabricate the primary proton battery and proton exchange membrane fuel cell (PEMFC). The observed open-circuit voltage for primary proton battery is 1.60 V (without GQD) and 1.62 V (with GQD). Proton exchange membrane fuel cell (PEMFC) has been constructed and it shows a voltage of 625 mV and its performance has been studied.","PeriodicalId":599,"journal":{"name":"Ionics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the booming development of portable electronic devices and new-energy electric vehicles demands higher energy and power densities from LIBs, while the current commercial cathode materials are difficult to meet the new requirements for battery performance in emerging markets owing to their low theoretical capacities. Vanadium oxides, for their abundant reserves, low cost, and high capacity, are considered to be strong candidates for anode materials for next-generation lithium-ion batteries. In this work, we firstly briefly summarize the research progress of traditional cathode materials for lithium-ion batteries, followed by an overview of vanadium oxides as potential cathode materials for lithium-ion batteries, and we distill, categorize, and summarize the efforts that have been carried out on vanadium oxides in recent years. In the end, based on the advantages and disadvantages of vanadium oxide materials, several reasonable outlooks on their future research directions, challenges, and modification methods are proposed according to the current research status to satisfy the needs of both basic research and practical applications.","PeriodicalId":599,"journal":{"name":"Ionics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141940000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It examines the impact of hydrothermal treatment and calcination on the structure and performance of the materials. The results indicate that, due to the chelation of phenolic hydroxyl groups in TA with nickel and cobalt ions, hydrothermal conditions facilitate the formation of needle-like arrays of metal–organic coordination crystals, which can effectively increase the specific surface area of the electrode. The optimally synthesized electrode demonstrates an exceptional specific capacitance of 1337 F·g−1 (668.5 C·g−1) at a current density of 1 A·g−1. Furthermore, when assembled into an asymmetric supercapacitor with activated carbon, it achieves a notably high energy density of 21.4 Wh·kg−1 at a power density of 800 W·kg−1. This superior performance is attributed to the higher specific surface area of the coordination crystals, which provides more active sites. These findings reveal that TA-modified Ni-Co bimetallic electrodes are promising for high-performance supercapacitors.","PeriodicalId":599,"journal":{"name":"Ionics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of expensive metal-dye complexes, the lack of long-term stability due to the use of liquid electrolytes, and the use of rare and expensive Pt as the CE are the major drawbacks preventing the large-scale production of DSSCs. However, recent studies showed alternative materials can be used to enhance the DSSC performance. The unique properties of graphene make it an ideal additive to improve the functions of all three components of DSSCs. Graphene’s high optical transmittance and electron mobility are suitable to improve transparent conducting substrates and nanostructured wide bandgap semiconductor layers of the photoelectrode. Graphene quantum dots have a wide absorption spectrum and thus can be used as photosensitizers. High catalytic activity, high electrical conductivity, high corrosion resistance, and a larger specific surface area make graphene and its composites suitable for making CEs. In addition, graphene has been used to improve composite electrolytes intended for DSSCs. Considering all these facts, this article reviews the recent developments and applications of graphene-based materials in photoelectrodes, electrolytes and CEs and the possible uses of graphene to improve DSSCs.","PeriodicalId":599,"journal":{"name":"Ionics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141939999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regrettably, silicon has not been widely adopted in practical applications due to its low electrical conductivity, recurrent volume changes, continuous side reactions with the electrolyte, and an unstable solid electrolyte interface. These challenges result in a loss of electrical contact with the current collector, leading to poor cycle life and hindering the widespread adoption of silicon as an anode for LIBs. Various effective strategies have been explored to address these issues, such as the construction of Si nanostructures with diverse architectures to accommodate volume expansion and the synthesis of Si composites. Anodes with polymer coating, particularly those of natural origin, have attracted attention in the scientific community. This article reviews the significant impact of silicon-coated polymer anodes in recent years, providing a summary of advancements in real capacity, preparation methods, cycling stability, and Coulombic efficiency.
