纳米材料的独特性质使其在能源应用中具有潜在的应用前景。由于纳米材料的结构和性能不同，研究单个纳米材料并将其性能与结构相关联是非常重要的。在这篇综述中，我们总结了原位电子显微镜方法，以探索用于能源应用的纳米材料的重要性质及其性质-结构关系，重点是我们实验室开发的那些方法。通过在扫描电子显微镜上进行的原位纳米操纵，可以明确能源材料的机械、机电和光电性能，并将其与结构相关联。在环境气氛中，可以直接观察到电池中发生的电化学反应。结合以上测试结果，可以对能量材料的机械稳定性、机理和寿命进行评估，在此基础上可以提高材料的性能，探索新的应用领域。
The unique properties of nanomaterials have made them potential candidates in energy applications. Due to the different structures and properties of nanomaterials, it is very important to study individual nanomaterials and correlate their properties to structures. In this review, we summarise in-situ electron microscopy methods for probing important properties of the nanomaterials for energy applications and their property-structure relationships, with an emphasis on those developed in our laboratory. Through the in-situ nanomanipulation conducted in a scanning electron microscope, the mechanical, electromechanical properties and photoelectronic properties of energy materials can be clarified and correlated to their structures. With the environmental atmosphere, electrochemical reactions occurred in batteries can be directly observed. Combined with the above measurements, the mechanical stability, mechanism and duration of the energy materials can be evaluated, based on which the performance of the materials can be improved and novel applications can be explored.
