Simultaneous Analysis of Evolved Gas Produced by the Degradation of a Lithium-Ion Battery(GC)
In evaluating the degradation of lithium-ion rechargeable batteries, it is necessary to analyze the gases produced inside the battery. The composition of the sampled internal gases can be investigated by conveying them to a gas chromatograph.
The Shimadzu Tracera High-Sensitivity Gas Chromatograph uses a revolutionary plasma technology to detect all compounds except He and Ne. The system is capable of the simultaneous analysis of C1 to C3 hydrocarbons and inorganic gases including hydrogen, so it eliminates the conventional need for carrier gas switching or combined use of multiple systems. In addition, the Tracera's high sensitivity makes it possible to analyze small quantity gas samples.
This Data introduces the simultaneous analysis of internal gases from a lithium-ion rechargeable battery utilizing the Tracera system.
