NiS nanoparticles by the NaCl-assisted less-liquid reaction system for the magnesium-ion battery cathode.

Rechargeable magnesium batteries are expected to be the next generation of energy storage devices. Therefore, it is of great significance to develop low-cost and long-life magnesium (Mg) electrode materials. However, the traditional method of synthesizing electrode materials is complicated, and it is difficult to remove potentially dangerous impurities.

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

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 Mg in the cathode material limit the development of practical Mg cathode materials. In this paper, an anion-rich electrode material, NiS , and its composite with Ni-based carbon nanotubes (NiS /NCNTs) are explored as the cathode materials for Mg-ion batteries.
