An apparatus for quantitatively analyzing gas, particularly oxygen, generated in a battery material, particularly a cathode material is provided. The apparatus contains a switching valve and a sampling loop in a pyrolyzer, thereby allowing an EGA method, which was used only for the qualitative analysis of gas generated from a solid sample, to be used for the quantitative analysis of gas generated at a specific temperature when heat is applied by the pyrolyzer in a battery material.

Apparatus for quantitatively analyzing oxygen generated in battery material

An apparatus for generating gas from a sample (battery) by pyrolysis of the sample in order to collect or analyze gas generated inside the sample due to the thermal behaviors of the sample. More specifically, provided is an apparatus wherein not only gas generated due to the thermal behaviors of a sample (battery) can be generated by heating the sample (battery itself), but also a series of processes provided to collect or analyze the generated gas can be automatically controlled.

Automated apparatus for sample pyrolysis
