Si-based rechargeable lithium-ion batteries (LIBs) have generated interest as silicon has remarkably high theoretical specific capacity. It is projected that LIBs will meet the increasing need for extensive energy storage systems, electric vehicles, and portable electronics with high energy densities. However, the Si-based LIB has a substantial problem due to the volume cycle variations brought on by Si, which result in severe capacity loss. Making Si-based anodes-enabled high-performance LIBs that are easy to utilize requires an understanding of the fading mechanism. Due to its distinct advantage in morphological changes from microscale to nanoscale, even approaching atomic resolution, electron microscopy is one of the most popular methods. Based on operando electron microscopy characterization, the general comprehension of the fading mechanism and the morphology evolution of Si-based LIBs are debated in this review. The current advancements in compositional and structural interpretation for Si-based LIBs using advanced electron microscopy characterization methods are outlined. The future development trends in pertinent silicon materials characterization methods are also highlighted, along with numerous potential research avenues for Si-based LIBs design and characterization.

使用原位/操作电子显微镜对硅阳极的表面/界面形貌演变进行成像
硅基可充电锂离子电池 (LIB) 引起了人们的兴趣，因为硅具有非常高的理论比容量。预计 LIB 将满足对广泛的储能系统、电动汽车和具有高能量密度的便携式电子产品日益增长的需求。然而，由于Si带来的体积循环变化，导致Si基LIB存在严重的问题，导致严重的容量损失。制造易于使用的基于 Si 阳极的高性能 LIB 需要了解衰落机制。由于其在从微米级到纳米级甚至接近原子分辨率的形态变化方面的明显优势，电子显微镜是最受欢迎的方法之一。基于操作数这篇综述讨论了电子显微镜表征、衰退机制的一般理解和 Si 基 LIB 的形态演化。概述了使用先进的电子显微镜表征方法对 Si 基 LIB 的成分和结构解释的当前进展。还强调了相关硅材料表征方法的未来发展趋势，以及硅基 LIB 设计和表征的众多潜在研究途径。
