Metal oxides/MnO 2 hierarchical hollow hybrid nanostructures have attracted significant attention because of their wide potential applications. However, the exploration of a general synthetic approach for fabricating hierarchical hollow hybrid nanostructures is still a great challenge. Herein, a “penetration‐carbonization and reduction‐coating–annealing” route is presented for the generalized synthesis of metal oxides/MnO 2 hierarchical hollow hybrid spheres, including NiO/MnO 2 , Co 3 O 4 /MnO 2 , and CuO/MnO 2 . Because of the unique hierarchical hollow hybrid nanostructures, NiO/MnO 2 nanomaterials possess a desirable capacity (1520 mA h g −1 ) and outstanding cyclic stability (909 mA h g −1 at the 200th cycle) as Li‐ion battery anode materials. The work reported herein can not only pave the way for the generalized synthetic strategy of metal oxides/MnO 2 hierarchical hollow hybrid nanostructures, but also provide a promising application of NiO/MnO 2 nanomaterials for Li‐ion battery anode.
