课程描述

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。

感谢您参加《锂电材料产气分析——热质联用系统》在线课程。本次课程由耐驰仪器新能源行业产品支持周延主讲。
