Precipitation synthesis and enhanced electrochemical performance of graphene-modified LiMn2O4 for lithium-ion batteries

The graphene-modified LiMn 2 O 4 cathode material was synthesized by precipitation method. X-ray diffraction (XRD), scanning electron microscopy (SEM), and fourier transform infrared (FITR) showed LiMn 2 O 4 had been successfully combined with the graphene. The charge and discharge tests and electro...
