چکیده انگلیسی
Nickel particles with different contents of Ni3S2 surface layer were prepared for their application as cathode materials in Na/NiCl2 batteries. The surface modification of nickel particles is found to prevent their growth and battery degradation during cycling. The optimum level of surface modification was determined by electrochemical tests and morphology characterization. Excessive Ni3S2 layer seems to cause particle aggregation resulting in low reversible capacity. The capacity of the cell with optimum level of Ni3S2 surface modification layer after 50 cycles is about 4 times greater than that without Ni3S2 surface modification layer.
