Swelling Gas Analysis in Li-Ion using Agilent 990 Micro-GC
During recycling or storage of lithium-ion batteries, gases are produced due to film formation and oxidation of the electrolyte components, overcharge and over discharge of the battery.
Common gas-producing components include permanent gases (e.g., H2, CO, and CO2) and alkanes (e.g., CH4, C2H4, and C2H6).
