초록
In this study, fine cathode materials Ni3S2 and NiS2 were synthesized using the simple, convenient process of mechanical alloying (MA). In order to improve the cell properties, wet milling processes were conducted using low-energy ball milling to decrease the mean particle size of both materials. The cells of Na/Ni3S2 and Na/NiS2 show a high initial discharge capacity of 425 mAh/g and 577 mAh/g respectively using wet milled powder particles,which is much larger than commercial ones, providing some potential as new cathode materials for rechargeable sodium-ion batteries.
