چکیده انگلیسی
Composites of LiMn2O4 nanoparticles in a graphene matrix were prepared to compensate for the low electronic conductivity of the LiMn2O4 cathode. The LiMn2O4 nanoparticles were homogeneously dispersed and attached on the graphene surface by the hydrothermal method. The graphene/LiMn2O4 electrode showed higher discharge capacity and rate capability than a pristine LiMn2O4 electrode. This is attributed to the high surface area of LiMn2O4 nanoparticles and good electronic conductivity because of the presence of graphene. The composites of LiMn2O4 nanoparticles with graphene were also effective in stabilizing the cyclic performance of the LiMn2O4 nanoparticle cathode.
