Unlocking the stable interface in aqueous zinc-ion battery with multifunctional xylose-based electrolyte additives

Journal of Energy Chemistry 2025年第1期100卷 770-778页

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

“十四五”规划纲要指出应健全国家技术安全清单管理制度,对关系到国计民生和国家安全的重要技术实施清单化、系统化管理,加强技术对外转移的审查审批。作为国家技术安全规制的重要依据,国家技术安全清单是指政府为防范技术外流风险而以列举方式说明可能影响国家安全的关键敏感技术的制度,属于政府在法律授权下创设的旨在维护技术领域国家安全的权威型政策工具。在法律性质上,形式的规范性、内容的解释性和功能的双元性,决定了国家技术安全清单是一种兼具“规制”与“自制”功能的解释性行政规则。它在整个国家技术安全规制体系中发挥着承上启下的嵌合作用,既传递和体现顶层法律规范系统的要求,又支撑和规范底层监管执法系统的运转。然而,国家技术安全清单在实践过程中暴露出规范内容错漏、决策程序瑕疵、司法审查无力等问题,这些问题削弱了清单与依清单行政的合法性与最佳性,阻碍了制度功能的充分发挥。为在法治的轨道上统筹发展和安全,国家技术安全清单应对标法治政府建设要求整饬重塑,推进管制事项与管制规则的一体化说明、大众知识与专家知识的嵌入平衡以及清单可诉性和可证立性条件的补强优化。

Bursty bulk flows(BBFs)and dipolarization fronts(DFs)are two important phenomena responsible for the transport of energy,mass and magnetic flux from the Earth’s magnetotail to the inner magnetosphere during magnetosphere *** BBFs are defined as the high-speed flows of several hundred km/s in the central plasma sheet lasting about 10 minutes,while DFs are defined as,with much shorter time scale of several seconds,sharp increases in the northward magnetic field component in the plasma *** two phenomena

Measurements of convection electric field in the inner magnetosphere

引用

Science China(Technological Sciences) 2018年第12期61卷 1866-1871页

作者： LV Xin liu wenlong School of Space and Environment Beihang University

In this paper, we study the characteristic of large-scale convection electric field in the inner magnetosphere, using magnetospheric multiscale(MMS) observations between L=5 and L=8 over the period from September 1, 2015 to October 31, 2016,covering almost all magnetic local time(MLT). Observations show that the DC convection electric field generally has small variations in this region. We investigate whether the convection electric field is correlated with geomagnetic indices and solar wind parameters. It is found that, among the studied parameters, solar wind electric field, z component of interplanetary magnetic field, AE and Kp indices show good correlations with the averaged convection electric field. The results in this paper provide valuable information for understanding the role of electric field on the dynamics of the inner magnetosphere.

Plasma perturbations in the coexisting environment of VLF transmitter emission, lightning strokes and seismic activity

引用

Science China(Technological Sciences) 2018年第5期61卷 678-686页

作者： TAO Dan liu wenlong MA YuDuan School of Space and Environment Beihang University

We analyzed plasma perturbations occurring in the coexisting environment of powerful VLF transmitter emission, intense lightning strokes and strong seismic activity during pregnant period. The results suggest that anomalous electron bursts with energy dispersion in the range of ~100–350 keV, forming the "wisp" signature, are due to cyclotron resonance of electrons with monochromatic waves from the powerful NWC VLF transmitters during nighttime. The intense broad band VLF emissions (up-going 0+ whistlers) are observed while the DEMETER satellite goes through the region of intense thunderstorm activities at mid-latitudes. However, the effects of intense lightning activity and pregnant earthquake have little impact on this kind of stable energy-dispersed electron structures, despite the fact that they are presumably two primary reasons for the particle precipitation in the ionosphere. The case studied here provides us a valuable opportunity to address the various sources triggering the anomalous plasma perturbations in the ionosphere.
