Beschreibung
Zusammenfassung:	A negative electrode material for a lithium ion battery, a negative electrode for a lithium ion battery, a lithium ion battery, a battery pack and a battery powered vehicle are disclosed herein. The negative electrode material for the lithium ion measured by means of XPS has a half-value width of 0.55-7 eV at a peak of 284-290 eV; a C/O atomic ratio of (65-75):1, and a peak area ratio of sp2C to sp3C of 1:(0.5-5) with the sum of the spectral peak areas of sp2C and sp3C being a reference. Using the negative electrode material having the structure above for the negative electrode of the lithium ion battery may provide a large lithium storage, and form a stable SEI film, thereby improving the stability of the negative electrode of the lithium during a cycling process, and improving the rate performance of the lithium ion battery.
