In this 27-minute video lesson, Kieran Evans, applications scientist in material characterization at PerkinElmer, shares tips for confident battery chemicals and materials characterization testing. These tips can help you meet composition and performance standards, and tackle common challenges, such as degradation analysis and impurity control.
Take an analytical look at expanders used in lead acid batteries, as well as electrode quality using both; DMA on coated sheets, and TG-MS adsorb water, and CO2. Learn to investigate polymer-based film membranes, including polyvinylidene (PVDF) and PP/PE/PP tri-layer membranes, to determine safety limits associated with overheating.
You’ll hear about practical methods using IR, TGA, DSC, DMA, and hyphenated technologies.
- Explore separator analysis, including PVDF for safety measurements in overheating.
- Analyze expanders used in lead acid batteries.
- Discover the power of DMA analysis for coated electrode sheets and TG-MS to analyze electrode quality for absorbed water and CO2
