Analysis of Gas Generated from Lithium Ion Rechargeable Battery Cells

Electrolytic solutions in lithium ion rechargeable batteries consist of organic solvents (mainly composed of the carbonate series), electrolytes, and additives.GC-MS systems are effective for the analysis of the denatured components of electrolytic solutions resulting from the charging and discharging of batteries. This article introduces a sample analysis of gas produced from a lithium ion rechargeable battery cell stored for 5 days at 80 ℃ cold areas like Hokkaido and hot areas like Okinawa.
