Abstract: We report the synthesis of sandwich-structured graphene–nickel silicate–Ni ternary composites by using the solvothermal method followed by asimple in situ reduction procedure. The composites show an interesting structure with graphene sandwiched between two layers of well-dispersed Ni nanoparticles (NPs) anchored on ultra-thin nickel silicate nanosheets. These ternary composites exhibit enhanced performance as anode materials owing to the synergistic effect between the graphene matrix and electrochemically inert Ni nanoparticles,aneffect that holds promise for the design and fabrication of other advanced electrode materials.
