In this work, using ZnCl2 as a hydrogen bond acceptor and lactic acid (LA) as a hydrogen bond donor, an inorganic salt-based deep eutectic solvent (DES) was designed. The DES was used to extract lignin from poplar sawdust, and then poly(vinyl alcohol) was added to the mixed DES/lignin solution to obtain the eutectogels. Due to extensive hydrogen bonding and Zn2+-induced coordination, the eutectogels present high ionic conductivity, good stretchability, and wide temperature tolerance. In particular, the presence of lignin endows the eutectogel with self-adhesive properties and enhanced mechanical strength. By regulating the lignin content, the optimal eutectogel sample exhibited an ionic conductivity of 23.8 mS cm-1, tensile strength of 331 kPa, and elongation at break of 1000%, and it could be stable for a long time at -20 °C. Furthermore, the eutectogel quasi-solid-state electrolyte in a zinc-ion hybrid supercapacitor has a high capacity of 251 mA h g-1 at 0.5 A g-1, and it provides stable adhesion and mechanical strength at low temperatures. After 10,000 charge/discharge cycles, these capacitors demonstrated over 86% capacitance retention and 100% Coulombic efficiency.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, gel polymer electrolytes (GPEs) that offer flame retardancy, good ion transport performance, and stable Li deposition ability to inhibit the growth of lithium dendrites are ideal for LMBs with high safety. In this study, a novel comb-like flame-retardant gel polymer electrolyte (C-GPE) is developed by grafting polyethylene glycol (PEG) and 3-aminopropylphosphonic acid (3-APPA). The host polymer is poly(methyl vinyl ether-alt-maleic anhydride), and 1-M LiTFSI in EC/DEC served as the Li salt and plasticizer. The C-GPE considerably enhances LMBs performance in two key aspects. First, it exhibited an excellent flame-retardant property. The decomposition of grafted 3-APPA generated PO· free radicals, which effectively captures highly reactive radicals, rendering C-GPE nonflammable and enhancing the safety of LMBs. Second, the highly stable SEI layer containing Li3PO4, and LixPOyFz in C-GPE-15|Li can inhibit lithium dendrite growth, promote uniform Li metal deposition and improve the long-term cycling stability of LMBs.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, the electrospun nanofibers have shown promising prospects in the high-performance humidity sensors due to their large specific surface area and high porosity.

However, there has been little focus on the inherent structure of the zinc foil itself. The traditional Zn anode has uneven rough surfaces that can lead to nonuniform charge distribution and hinder nucleation, thereby triggering the “tip effect” that can induce the formation of adverse dendrites. In this study, the conventional Zn foil was examined using simple pretreatments such as mechanical polishing and chemical etching that have the potential to substantially improve the electrochemical properties. Compared with bare Zn (b-Zn) and polished Zn (p-Zn), chemically etched Zn (e-Zn) sustained a remarkable life cycle of up to 5000 cycles with ∼71% cycling retention at a high current density of 5 A g<small>⁻¹</small> using V<small>₂</small>O<small>₅</small>·<em>n</em>H<small>₂</small>O as a cathode material.

This superior performance of the e-Zn is attributed to its unique 3D structure that effectively accommodates Zn dendrites, as confirmed by XRD and EBSD analyses, which reveal Zn deposition along the (002) plane with lower surface energy as compared with other planes. This approach provides a straightforward and industrially scalable method for expanding ZIB utilization.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, it offers insight into the electrochemical performance to various structural architecture outcomes. Different morphologies, such as layered, nanosheet-assembled flower, rod, and sphere structures, have resulted from implementing distinct organic ligands. The as-synthesized microporous phosphonates (MnBPA, MnPPA, MnDPA, and MnNAPH) have been thoroughly characterized, which signifies the proper incorporation of the organic ligands in the hybrid framework. The electrochemical performance in an alkaline medium has also been examined in a wide voltage window of 1V. The regular microporous nature and large surface area, which facilitate faster ionic transport, display a maximum capacitance of 846 F g-1 for MnBPA compared to other as-prepared electrode materials. A striking energy density (E.D.) of 156.6 Wh kg-1 and a power density (P.D.) of 1658 W kg-1 was attained by an asymmetric coin cell device using the best electrode MnBPA as the cathode component. Furthermore, moving toward contemporary technology, an asymmetric in-plane interdigital structured flexible micro-supercapacitor was fabricated using an inexpensive vacuum filtration technique. The strategically designed interdigital structure, which was used as a customized mask, effectively reduces the ion-diffusion path, resulting in a high areal capacitance of 105.2 mF cm-2.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142236731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
