Abstract

In order to investigate the electrochemical properties ofLi/FeScell,FeSpowder was fabricated by using a high-energy ball milling method. Then, surface ofFeSpowder 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 ofFeSelectrode forLi/FeScell 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, andFeScathode in turn. From the results, electroless nickel platedFeSelectrode showed very high initial discharge capacity of 581 mAh/g-FeS. And also, it showed higher discharge capacity than that of bareFeSelectrode until the 29th cycle. Therefore, it is found that metallic nickel gives beneficial effects on enhancing the electrical conductivity ofFeScathode material. 82.47.Cb.
