| Abstract: | We first design and synthesize a MWNT/C/Mg1.03Mn0.97SiO4 hierarchical nanostructure composed of MWNTs pinning the surface of the Mg1.03Mn0.97SiO4 nanoparticles, with simultaneous tethering to Mg1.03Mn0.97SiO4 particles via an interfacial amorphous carbon phase bonding, through a facile CVD method. It is further demonstrated that the nanocomposite exhibits a reversible capacity as high as 300 mAh g−1 at 0.2 C and a stable cycling performance at 0.5 C when utilized as a cathode material for rechargeable magnesium batteries. |
