Abstrakt:	The Li[LiMnNiCo]O materials doped with different Mo content were studied using electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), and X-ray diffractometry (XRD). The electrochemical properties were also measured. An increase of Mo content resulted in a bigger lattice volume and a lower cation disorder. In addition, the electrochemical performance was enhanced with the increasing Mo content. However, more aggregation of particles was found to occur at a higher Mo content, which resulted in worse electrochemical performance. The highest electrochemical performance was obtained with a 5 mol% Mo addition. [ABSTRACT FROM AUTHOR]
