This video from Anton Paar focuses on the critical measurement of BET surface area for electrode materials in lithium-ion batteries. In this video, Anthony explains how to use gas sorption data to quantify the specific surface area, a key physical property impacting battery performance.
The process begins with accurately weighing the sample using a precise microbalance, followed by degassing to ensure the sample is completely dry. Anthony details how to set up the degassing process in the software, including selecting the appropriate temperature, typically between 80 to 150 degrees Celsius, for battery materials.
Once degassing is complete, the sample is re-weighed and the updated weight is used to compute the BET surface area.
Anthony also explains how to select and modify analysis profiles, and initiate the analysis through software or touchscreen controls. The BET surface area is automatically calculated and displayed, providing essential data influencing the battery's capacity and charge/discharge rates.
This video provides a step-by-step guide to accurately measuring BET surface area, highlighting its importance in optimizing lithium-ion battery performance.
