摘要
Abstract
Nix Co1-x S2 ( x=0, 0. 1, 0. 3, 0. 5, 0. 7, 0. 9, 1. 0 ) powders were prepared by hydrothermal method using NiCl2 , CoSO4 and Na2 S2 O3 and characterized with X-ray diffractometer( XRD) , scanning elec-tron microscope, laser particle size distribution analyzer and differential thermal analyser( DTA) . A single cell was prepared with a Nix Co1-x S2 cathode, a LiSi anode and a LiCl-KCl ( MgO ) molten salt electrolyte by pressed-power process. The effects of Ni and Co contents in Nix Co1-x S2 cathode materials on the discharge performance of thermal battery were investigated. The results suggest that the single cell cathode material with Ni0. 3 Co0. 7 S2 cathod has the best performance and the resistance is relatively low. The cell voltage can reach 1. 899 V, and the specific capacity can reach 276. 5 mA·h/g with a cut-off voltage of 1. 5 V at a constant current density of 100 mA/cm2 and a temperature of 450 ℃.关键词
