    Abstract SnO2@C@Fe3O4 sandwich-like hollow nanospheres are rationally synthesized by the surface adsorption of Fe(II) and the subsequent growth of Fe3O4 on the SnO2@C hollow nanospheres. In the novel nanostructures, the SnO2 internal layer can supply an indurative and hollow framework, which can buffer the repetitive volume variation during cycles. The conductive carbon interlayer can apparently improve the electronic conductivity and efficiently avoid the aggregation of Fe3O4 and SnO2 nanoparticles. Fe3O4 nanoparticles on the surface can strengthen the walls of hollow nanospheres, which is beneficial to the structural integrity and thus improves the cycling stability. Moreover, the effects of the calcination temperature on the properties of anode nanomaterials are also investigated. The grain size of Fe3O4 nanoparticles on SnO2@C@Fe3O4 composites gradually expands with the increasing calcination temperature. The electrochemical properties of SnO2@C@Fe3O4 composites are optimized by bridging the respective merits of SnO2, C as well as Fe3O4 and adjusting the calcination temperature. It is found that the SnO2@C@Fe3O4 hollow nanospheres at 500 °C exhibit a high specific capacity (1468.1 mAh g–1) and an extraordinary cycling stability (1007.6 mAh g–1 after the 100th cycle). It is expected that this synthesis strategy can be further applied to the rational design of other nanomaterials for energy storage.

    Abstract SnCo@C@Mn₃O₄ yolk–shell hierarchical hybrid nanocubes are successfully fabricated via the thermal reduction of CoSn(OH)₆@polydopamine and the subsequent surface-coating of Mn₃O₄ nanoparticles on the carbon layer. In the novel yolk–shelled nanostructures, the multiple SnCo alloy nanocores decrease the size of alloy nanoparticles and provide sufficient sites for the lithiation of Sn. Simultaneously, N-doped carbon as the intermediate layer prevents the agglomeration between SnCo and Mn₃O₄ nanoparticles and thus improves their structural stability. More importantly, Mn₃O₄ nanoparticles reinforce the carbon shell of yolk–shell nanostructures while decreasing the carbon content, resulting in high capacity and outstanding cyclic stability of SnCo@C@Mn₃O₄ nanocubes. With the respective advantages of three nanocomponents and their synthetic effects, SnCo@C@Mn₃O₄ yolk–shell hierarchical hybrid nanocubes show impressive reversible capacity (999 mAh g–¹ at 0.1A g–¹ after 300 cycles) and outstanding high-rate cyclic stability (734 mAh g–¹ at 0.5A g–¹ after 650 cycles). This study provides new insight into the rational design of novel Sn-based nanocomposites for enhanced electrochemical properties.
