A convenient approach has been proposed to synthesize the cathode material-NiS2 for Na/NiS2 cells by mechanically alloying (MA), where after the wet milling process was applied with normal hexane as the milling solvent to make the well-distributed powder particles. The cell shows a high initial discharge capacity of 577 mAh/g with the electrolyte of 1 M NaCF3SO3 dissolved in TEGDME. |
