Title (EN) APPARATUS FOR QUANTITATIVELY ANALYZING OXYGEN GENERATED IN BATTERY MATERIAL
(FR) APPAREIL D'ANALYSE QUANTITATIVE DE L'OXYGÈNE GÉNÉRÉ DANS UN MATÉRIAU DE BATTERIE
(KO) 전지재료에서 발생되는 산소의 정량분석 장치
Abstract:
(EN) The present invention relates to an apparatus for quantitatively analyzing gas, particularly oxygen, generated in a battery material, particularly a cathode material, in which by further installing a switching valve and a sampling loop in a pyrolyzer, an EGA method, which was used only for the qualitative analysis of gas generated from a solid sample, can be used for the quantitative analysis of gas generated at a specific temperature when heat is applied by the pyrolyzer in a battery material.
(FR) La présente invention concerne un appareil d'analyse quantitative du gaz, en particulier de l'oxygène, généré dans un matériau de batterie, en particulier un matériau de cathode, dans lequel, en installant en outre une vanne de commutation et une boucle d'échantillonnage dans un pyrolyseur, un procédé d'analyse des gaz émanents (EGA), qui a été uniquement utilisé pour l'analyse qualitative du gaz généré par un échantillon solide, peut être utilisé pour l'analyse quantitative du gaz généré à une température spécifique lorsque de la chaleur est appliquée par le pyrolyseur dans un matériau de batterie.
(KO) 본 발명은 전지재료, 특히 양극재료에서 발생되는 가스, 특히 산소의 정량분석 장치에 관한 것으로, 열분해기에 스위칭 밸브와 샘플링 루프를 추가 설치함으로써, 고체 시료에서 발생되는 가스의 정성분석에만 사용되었던 EGA법을 전지재료에서 열분해기에 의해 열을 가할 시 특정 온도에서 발생되는 가스의 정량분석에도 이용할 수 있게 되었다.
