The preparation and lithium battery performance of core-shell …
Herein, a ternary nanocomposite, SiO 2 @Fe 3 O 4 @C (SFC) with dual core-shell structure (Fig. 1), was prepared by a one-step hydrothermal method using SiO 2 nanospheres as solid template. In order to avoid the agglomeration of Fe 3 O 4 nanoparticles, SiO 2 nanospheres are introduced to serve as the supporter to immobilize …
