锂电材料产气分析——热质联用系统 (Analysis of Gas Production from Lithium Battery Materials - TG-QMS System)

Chinese Language
10:00 – 11:00 AM CST

电池鼓包是指电池内部的化学反应产生的气体导致电池外包装膨胀变形的现象,这种情况可能会导致电池的性能下降甚至引发安全问题。想要彻底解决这个问题,需要从材料层面入手,对锂电材料进行产气分析,材料含水量,分解释氧量,毒害气体产出等都是研究中的关注点。热分析质谱联用体系就能够很好地完成上述工作,相比于传统的集气再进行GCMS分析,热质联用体系还额外提供了热重和温度信息,通过联用测量结果我们可以知道锂电材料在什么温度下溢出了什么气体,再借助PTA附件,特定气体的释放量也可以计算得到。 

此次报告就将结合具体案例,告诉大家如何利用热分析联用系统帮助我们对不同种类的锂电材料进行逸出气体分析。 

Battery bulging refers to the phenomenon where gases produced by chemical reactions inside the battery cause the battery's outer packaging to expand and deform. This situation can lead to a decline in battery performance and even pose safety risks. To thoroughly address this issue, it is necessary to start from the material level, conducting gas analysis on lithium battery materials. Factors like moisture content in materials, the amount of oxygen released during Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition, and the production of toxic gases are all focal points in research. A thermal analysis mass spectrometry coupling system is well-suited to perform the aforementioned tasks. Compared to traditional methods of collecting gas for GCMS analysis, the TG-QMS coupling system additionally provides information on thermal weight and temperature. From the measurement results, we can determine at what temperature specific gases are emitted from the material. With the help of a PTA attachment, the amount of specific gas released can also be calculated. 

This webinar will combine application cases to show how TG-QMS system can help us analyze evolving gases from different types of lithium battery materials.
