在过去的十年中，利用真空方法如透射电子显微镜（TEM）来评估锂离子电极的反应途径已经成为一种流行的方法。然而，这些研究中的绝大多数都没有在与电池相关的电位下进行电化学反应和/或表征电解反应。在这里，我们展示了一种简单而灵活的方法，结合了固体和液体电解质的优点，实现了多种状态表征方法，包括光学成像、电学测量、x射线光电子能谱、x射线衍射、原子力显微镜和透射电子显微镜。这项工作证明了这些方法在电化学相关电位下的转换阳极ZnO电解锂化过程中应用于新型电池。
In the last decade, reacting Li ion electrodesin situusing vacuum based methods such as transmission electron microscopy (TEM) has become prevalent for assessing their reaction pathways. However, the vast majority of these studies do not perform electrochemical reactions at potentials relevant to batteries and/or characterize electrolytic reactions. Here we demonstrate a simple and flexible approach combining the benefits of solid and liquid electrolytes to enable diversein situcharacterization methods, including optical imaging, electrical measurements, X-ray photoelectron spectroscopy, X-ray diffraction, atomic force microscopy, and transmission electron microscopy. This work demonstrates these methods applied to the novel cell during electrolytic lithiation of the conversion anode ZnO at electrochemically relevant potentials.
