Abstract
In this work, the surface of LiNi1/3Co1/3Mn1/3O2 (NCM) cathodes prepared by the conventional method is modified with graphene oxide (GO) by dipping method. The X-ray diffraction (XRD) tests display that the crystalline structure of the modified NCM cathodes does not change obviously. The morphology of the pristine and modified NCM cathodes are characterized by scanning electron microscopy (SEM), and the results reveal that increased graphene oxide are detected on the surface of the modified NCM cathodes. The rate capability and cycling performance of both cathodes are evaluated by galvanostatic charge and discharge tests, and it can be concluded that the modified NCM cathodes have better cycling performance and high rate capability than the pristine NCM samples at a cut-off voltage of 4.3V. The results of the CV test and EIS test demonstrate that the additional graphene oxide can slow down the increase of electrochemical polarization.
