TLDR
In this article, a high-energy ball milling method was used to construct Li/FeS cells, and the surface of the FeS powder was coated with metallic nickel to obtain high initial discharge capacity of 581 mAh/g-FeS.Abstract:
In order to investigate the electrochemical properties of Li/FeS cell, FeS powder was fabricated by using a high-energy ball milling method. Then, surface of FeS powder was coated with metallic nickel. Nickel coating was conducted by using electroless nickel plating method. Nickel chloride (NiCl2 · 6H2O) was used as the nickel ion source for electroless nickel plating. The effects of nickel coating on the electrochemical properties of FeS electrode for Li/FeS cell were investigated by CV measurement and charge/discharge tests. Then, cells for electrochemical tests were assembled by stacking a lithium anode, separator containing liquid electrolyte, and FeS cathode in turn. From the results, electroless nickel plated FeS electrode showed very high initial discharge capacity of 581 mAh/g-FeS. And also, it showed higher discharge capacity than that of bare FeS electrode until the 29th cycle. Therefore, it is found that metallic nickel gives beneficial effects on enhancing the electrical conductivity of FeS cathode material. 82.47.Cb.read more
