Zusammenfassung:he thermal degradation mechanism of LixNi0.70Co0.15Al0.15O2 and LixNi0.90Mn0.10O2 (x = 0.50 and 0.30) was studied by thermal gravimetric analysis coupled with mass spectrometry. Correlation with in situ X-ray diffraction experiments was then achieved to determine the degradation mechanism and to explain the differences in thermal stability observed depending on the material composition. The degradation occurs in two steps: ...
