Zn（TFSI）2-Mediated Ring-Opening Polymerization for Electrolyte Engineering Toward Stable Aqueous Zinc Metal Batteries

Nano-Micro Letters 2025年第05期 487-499页

作者： Zhenjie Liu Murong xi Rui Sheng Yudai Huang Juan Ding Zhouliang Tan Jiapei Li Wenjun Zhang Yonggang wang State Key Laboratory of Chemistry and Utilization of Carbon Based Energy Resources College of ChemistryXinjiang University Department of Materials Science and Engineering&Center of Super-Diamond and Advanced Films City University of Hong Kong Department of Chemistry and Shanghai Key Laboratory of Molecular Catalysis and Innovative Materials Institute of New EnergyiChEM(Collaborative Innovation Center of Chemistry for Energy Materials)Fudan University

Practical Zn metal batteries have been hindered by several challenges, including Zn dendrite growth, undesirable side reactions, and unstable electrode/electrolyte interface. These issues are particularly more serious in low-concentration electrolytes. Herein, we design a Zn salt-mediated electrolyte with in situ ring-opening polymerization of the small molecule organic solvent. The Zn（TFSI）2salt catalyzes the ring-opening polymerization of(1,3-dioxolane（DOL）),generating oxidation-resistant and non-combustible long-chain polymer(poly（1,3-dioxolane）(pDOL)). The pDOL reduces the active H2O molecules in electrolyte and assists in forming stable organic–inorganic gradient solid electrolyte interphase with rich organic constituents, ZnO and ZnF2. The introduction of pDOL endows the electrolyte with several advantages: excellent Zn dendrite inhibition, improved corrosion resistance, widened electrochemical window（2.6 V）, and enhanced low-temperature performance（freezing point =-34.9 °C）. Zn plating/stripping in pDOL-enhanced electrolyte lasts for 4200 cycles at 99.02% Coulomb efficiency and maintains a lifetime of 8200 h. Moreover,Zn metal anodes deliver stable cycling for 2500 h with a high Zn utilization of 60%. A Zn//VO2pouch cell assembled with lean electrolyte(electrolyte/capacity(E/C = 41 mL（Ah）-1) also demonstrates a capacity retention ratio of 92% after 600 cycles. These results highlight the promising application prospects of practical Zn metal batteries enabled by the Zn（TFSI）2-mediated electrolyte engineering.

Background The aim of this study was to determine whether and how Zn proteinate with moderate chelation strength(Zn-Prot M)can alleviate heat stress(HS)-induced intestinal barrier function damage of broilers.A completely randomized design was used for comparatively testing the effects of Zn proteinate on HS and non-HS *** high temperature(HT),a 1(Control,HT-CON)+2(Zn source)×2(added Zn level)factorial arrangement of treatments was *** 2 added Zn sources were Zn-Prot M and Zn sulfate(ZnS),and the 2 added Zn levels were 30 and 60 mg/*** normal temperature(NT),a CON group(NT-CON)and pair-fed group(NT-PF)were *** The results showed that HS significantly reduced mRNA and protein expression levels of claudin-1,occludin,junctional adhesion molecule-A(JAMA),zonula occludens-1(ZO-1)and zinc finger protein A20(A20)in the jejunum,and HS also remarkably increased serum fluorescein isothiocyanate dextran(FITC-D),endotoxin and interleukin(IL)-1βcontents,serum diamine oxidase(DAO)and matrix metalloproteinase(MMP)-2 activities,nuclear factor kappa-B(NF-κB)p65 mRNA expression level,and protein expression levels of NF-κB p65 and MMP-2 in the ***,dietary supplementation with Zn,especially organic Zn as Zn-Prot M at 60 mg/kg,significantly decreased serum FITC-D,endotoxin and IL-1βcontents,serum DAO and MMP-2 activities,NF-κB p65 mRNA expression level,and protein expression levels of NF-κB p65 and MMP-2 in the jejunum of HS broilers,and notably promoted mRNA and protein expression levels of claudin-1,ZO-1 and *** Our results suggest that dietary Zn,especially 60 mg Zn/kg as Zn-Prot M,can alleviate HS-induced intestinal barrier function damage by promoting the expression of TJ proteins possibly via induction of A20-mediated suppression of the NF-κB p65/MMP-2 pathway in the jejunum of HS broilers.

由于航空事故的发生往往很难预测,而且是不可逆转的,因此如何制定有效的航空预警方案是避免事故发生的关键。针对航空安全风险预警问题,利用航空风险传播动力学模型,基于平均场理论解析航空系统事故触发概率,通过敏感性分析得出触发事件对航空事故发生的提升率,建立事前航空事故预警模型。结果发现,事前预警模型中应该分配更多的资源给能见度差、飞机系统故障、疲劳、特情处置不力、技能不足、设备维护不足等触发事件,从而避免上述事件的发生。通过航空事故风险传播规律,建立事中航空事故预警模型,得出受到触发事件影响的风险演化事件集合,并给出对应排序使得管理者可以做到资源的有效分配。

电机冷却是保障线性压缩机高可靠性运行的关键。建立了基于实验运行参数及温度的直线振荡电机损耗模型,分析了电机铜损、铁心损耗和涡流损耗随温度的变化趋势,并耦合线性压缩机流场三维模型,对电机线圈和永磁体的温度分布特性进行了变工况分析。结果表明:在相同的进气温度下,质量流量每提升0.2 g/s,电机温度降低4~20℃,且温度分布方差降低0.5~1.2;相同质量流量下,进气温度每降低5℃,电机温度降低4~6℃。永磁体的最大温差为0.6 g/s质量流量工况下的7.3℃和1.4 g/s质量流量工况下的6.9℃。优化后的进气结构使电机温度分布方差减小了5.521,最高温度下降了4.1℃,最大温差下降了4.55℃。
