リチウムイオン二次電池内に発生するガスのin-situ GC-MS分析法の開発
The in-situ GC-MS system was developed for detection of gases generated in a cell of lithium-ion secondary battery. The results showed that O2 gas arose from a Li2CuO2 electrode cell under the charging process. The O2 gas generation probably resulted from the phase transition of CuO2 during the charge curve.
