摘要
原位液相电化学透射电子显微镜(ec-TEM)作为一种宝贵的技术,已被广泛用于研究电池材料中的金属沉积。虽然研究人员利用微尺度 ec-TEM 液体电池对金属成核、生长和枝晶形成进行了实时观测,但现有电池沿电极的电场分布不均匀,限制了测量可靠性和定量分析。在此,我们为 ec-TEM 芯片引入了一种先进的电极设计,可确保电场均匀,从而精确表征更接近实际电池条件的早期金属沉积。模拟和实验研究表明,与市售芯片相比,这些专门设计的 ec-TEM 芯片有助于结合原位 TEM 技术进行定量电化学表征。因此,我们在优化液相 TEM 原位定量测量的性能和可靠性方面取得了重大进展,这对理解和改进电化学系统至关重要。
Advanced electrode design enables homogeneous electric field distribution for metal deposition studies via in situ liquid cell TEM
In situ liquid-phase electrochemical transmission electron microscopy (ec-TEM) as a valuable technique has been widely used in studying metal deposition in battery materials. While real-time observations of metallic nucleation, growth, and dendrite formation using microscale ec-TEM liquid cells are investigated, existing cells exhibit nonuniform electric field distribution along electrodes, limiting measurement reliability and quantitative analysis. Here, we introduce an advanced electrode design for ec-TEM chips, ensuring a uniform electric field for precise characterization of early-stage metal deposition closer to practical battery conditions. Both simulation and experimental investigations demonstrate that these specially designed ec-TEM chips facilitate quantitative electrochemical characterization combined with the in situ TEM technique in comparison with commercially available chips. We thus provide a significant progression toward optimizing the performance and reliability of quantitative in situ liquid-phase TEM measurements, essential for understanding and improving electrochemical systems.
期刊介绍:
Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results.
We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
