In Situ Anchoring Anion-Rich and Multi-Cavity NiS₂ Nanoparticles on NCNTs for Advanced Magnesium-Ion Batteries.

ABSTRACT: Magnesium (Mg)-ion batteries with low cost and good safety characteristics has attracted a great deal of attention recently. However, the high polarity and the slow diffusion of Mg²⁺ in the cathode material limit the development of practical Mg cathode materials. In this paper, an anion-rich electrode material, NiS₂ , and its composite with Ni-based carbon nanotubes (NiS₂ /NCNTs) are explored as the cathode materials for Mg-ion batteries. These NiS₂ /NCNTs with excellent Mg²⁺ storage property is synthesized by a simple in situ growth of NiS₂ nanoparticles on NCNTs. NiS₂ with both a large regular cavity structure and abundant sulfur-sulfur (SS) bonds with high electronegativity can provide a large number of active
