网络研讨会 | 使用能谱仪对电池进行表征和性能优化

来源：布鲁克纳米分析部分类：会展 2023-10-23 15:39:08 4阅读次数

电池化学成分和制造工艺的改进对于清洁能源和绿色经济至关重要。在实践中，能量密度、充电/放电额定值和电池寿命与电池内部的电化学反应以及因制造或循环而形成的结构特征有关。通常，所有这些参数的优化是一个多尺度、多模式的挑战，其中包括对阳极、阴极、电解质及其各自界面的分析研究。

在本次网络研讨会中，我们将重点关注能谱仪（EDS）与其他表征技术，以了解如何通过它们提供有关电芯性能和失效分析的关键信息。我们将展示ESPRIT软件如何与高灵敏度XFlash 760斜插式能谱仪和FlatQUAD平插式能谱仪相结合用于检测材料中可能存在某些元素或污染物的富集和低至ppm标度的局部元素分析。

欢迎各位老师借此机会，扩展您对电池研发中使用的先进SEM表征技术的了解。

期待您的参会！
