Summary:The development of an in situ high-temperature X-ray diffraction technique for lithium-ion battery materials is crucial for understanding the detailed mechanism of thermal runaway. We realized such a technique and employed it on a C 6 Li x electrode with an LiPF 6 -based electrolyte, thereby revealing multiple transformations through several intermediate stages, i.e. , C 6 Li → C 12 Li → C 18 Li/C 24 Li → C 36 Li → C 6 , which could be helpful to improve the thermal stability.
