摘要

我们利用同步辐射透射x射线显微镜研究了x射线损伤对电池阴极演化的影响。在operando硬币电池中，暴露在x射线束下可以诱导气泡的形成，潜在地使阴极颗粒在电化学上失去活性，并使颗粒从初始位置移位。然而，利用外部压力的袋细胞可以减轻气泡的形成及其相关的影响。

Mitigating X-ray-induced damage for accurate analysis of battery cathodes using transmission X-ray microscopy†

We investigate the impact of X-ray-induced damage on the evolution of battery cathodes using synchrotron transmission X-ray microscopy. In an operando coin cell, exposure to the X-ray beam can induce bubble formation, potentially rendering cathode particles electrochemically inactive and displacing particles from their initial position. However, utilizing external pressure on a pouch cell can mitigate bubble formation and its associated effects.
