The Analysis of Swelling Lithium-Ion Battery with a Residual Gas Analyzer
RGA provides valuable data for optimizing battery safety, performance, and longevity.
This application note aims to demonstrate the use of a Residual Gas Analyzer (RGA) in identifying and quantifying the gases produced by Li-ion battery swelling. By analyzing these gases, researchers and engineers can gain valuable insights into the battery’s chemical processes, identify potential failure modes, and optimize electrolyte formulations for enhanced battery performance and safety.
Lithium-ion (Li-ion) batteries have several key advantages including high energy densities, flexible design, light weight, fast charging, and long lifespan. These advantages have made Li-ion batteries the preferred choice for a wide array of devices, from consumer electronics to electric vehicles and renewable energy storage systems. Lithium-ion (Li-ion) batteries can swell (also known as “gassing”) due to several factors, primarily related to chemical reactions within the battery. Swelling is a serious issue because it can indicate a failure in the battery’s safety
mechanisms. Swollen batteries should not be used, as they can lead to further degradation, overheating, or even dangerous situations such as fires or explosions. Analyzing gases in swelling lithium-ion batteries can be crucial for understanding the causes and consequences of battery swelling, especially for safety and performance assessments.
