This project will construct a new transmission electron microscope (TEM) platform for operando electrochemical imaging, designed to identify electrochemical processes at unprecedented spatial resolution while operating under application-relevant conditions.Better batteries and electrocatalysts are essential for realising a sustainable future. Yet the complexity of their electrochemistry - with intertwined dependence on side-reactions, valence evolution, structural changes, and more - cannot be predicted just by modelling. Peering inside an operating cell will reveal these processes directly, enabling the informed design of future energy materials. Resolving many of these critical aspects still reside beyond the resolution limits of current in-situ characterisation methods.The core objectives of AIDEChem are: (i) To develop a new graphene-enabled electrochemical cell that will grant a unique high-resolution TEM imaging and spectroscopy capability for probing electrochemistry in-situ. (ii) To reveal previously inaccessible processes occurring in candidate electrochemical systems, including batteries and electrocatalysts, at ground-breaking resolutions. The new platform will be used to expose the nanoscale dynamics that govern electrochemical nucleation of nanostructures, epitaxial electrodeposition, nanobubble deactivation of electrodes, and electrocatalyst evolution; electrochemistry that is largely inaccessible with current in-situ microscopy technology. With the new technical capability realised in this platform, AIDEChem will provide the insights that are mandatory for the informed design of effective electrochemical energy materials, optimally tailored for the desired application.Delivery of AIDEChem will be possible due to the PI's combination of research skills - encompassing in-situ TEM, nanoscale device fabrication, 2D materials, and electrochemistry - and the TEM, nanofabrication, and electrochemistry facilities at Warwick University.

该项目将构建一个新的透射电子显微镜（TEM）平台，用于电化学成像，旨在以前所未有的空间分辨率识别电化学过程，同时在应用相关条件下运行。更好的电池和电催化剂对于实现可持续发展的未来至关重要。然而，它们的电化学的复杂性——与副反应、价演化、结构变化等相互交织的依赖——不能仅仅通过建模来预测。窥视电池内部将直接揭示这些过程，使未来能源材料的设计成为可能。解决这些关键方面的许多问题仍然超出了当前原位表征方法的分辨率限制。AIDEChem的核心目标是：(1)开发一种新型石墨烯电化学电池，该电池将提供独特的高分辨率TEM成像和光谱能力，用于原位探测电化学。（ii）以突破性的分辨率揭示在候选电化学系统（包括电池和电催化剂）中发生的以前难以理解的过程。新平台将用于揭示纳米结构的电化学成核、外延电沉积、电极的纳米泡失活和电催化剂演化的纳米级动力学；目前的原位显微镜技术在很大程度上无法实现电化学。凭借在该平台上实现的新技术能力，AIDEChem将为有效的电化学能源材料的知情设计提供必要的见解，并根据所需的应用进行最佳定制。AIDEChem的交付将是可能的，因为PI结合了研究技能-包括原位TEM，纳米级器件制造，2D材料和电化学-以及华威大学的TEM，纳米制造和电化学设施。
