Synthesis of Nickel-Coated FeS2 Particles as Active Material for Li/FeS2 Cell by Mechanical Alloying

Article Preview

Abstract:

In this study, the FeS2 fine compound powders for active material were made by mechanical alloying using the Spex mixer mill. As the total milling time increased to 15hrs, the size of FeS2 powder decreased to 0.98um. Meanwhile, the treatment of nickel coating for FeS2 powder were also prepared by mechanical alloying using the ball milling machine, which has attracted much attention from the standpoints of improving the cycle life property and good columbic efficiency.
