The study on the discharge performance of Li/FeS2 battery

According to the research of Li/FeS_2 battery, the technological parameters and process were introduced.Methods which could improve the discharge performance of Li/FeS_2 battery were studied. One was adding special additive in the cathode electrode, the other was increasing the quantity of inorganic salt in the electrolyte. The experimental results showed that the discharge performance of Li/FeS_2 battery such as discharge capacity and plateau voltage had noticeable improvement by adding metal, oxide, inorganic salt in the cathode electrode and increasing the quantity of inorganic salt in the electrolyte.According to test results of different discharge conditions, the best adding quantity was metal 0.5%, oxide 3%, inorganic salt 0.4%.
