Hierarchical hollow porous structures of nickel-doped λ-MnO₂ anodes for Li-ion energy storage systems.

ABSTRACT: Metal oxides with hollow porous structures are attractive and promising anode candidates for Li-ion batteries due to their high surface area, high loading capacity, and low density. In this work, hierarchical hollow porous structures of nickel (Ni)-doped λ-MnO₂ were prepared via a facile, and cost-effective approach, where different amounts of Ni were introduced into MnO₂ structures to tailor their physical and chemical properties. When the prepared Ni-doped MnO₂ hollow structures were studied as anode materials for Li-ion batteries, the electrode showed excellent electrochemical properties, such as stable cyclability and admirable rate capability. Moreover, Ni doping significantly enhances the diffusion properties of the active materials. The materi
