Sn—Sb—Ni ternary compound and method for forming the same
The invention discloses a novel method to prepare the Ni(Sn, Sb)3 skutterudite compound. Skutterudite compounds are thermoelectric materials, which can transform heat into electric energy. Besides, the Ni(Sn, Sb)3 compound is also an anode material of Li ion battery. The solid state diffusion method is used to prepare the Ni(Sn1-x, Sbx)3 compound. Compared to traditional physical or chemical processes, the method disclosed in the invention is simpler and operates at a lower temperature. By the method according to the invention, the composition of the Ni(Sn, Sb)3 compound can be adjusted to fulfill variety requirements for different applications. It is noteworthy that the invention can prepare ternary compounds. In comparison with the frequently used binary compounds such as Ni3Sn4 or Cu6Sn5, the invention can produce materials with better performance.
