摘要
Abstract
Nickel fluoride,as a new type of cathode material for thermal batteries,has the advantages of high voltage plateau,high theoretical specific capacity,and good thermal stability. However,the poor ionic conductivity characteristics inherent in NiF2 cause its unsatisfactory actual discharge per-formance. Eutectic salts are common positive electrode additives,which can reduce the diffusion re-sistance of electrolyte ions on the surface of NiF2 positive electrode materials by utilizing their high ion conductivity characteristics in the molten state,thereby improving electrochemical performance. In this paper,it is demonstrated that LiF-LiCl-LiBr eutectic salt additives can significantly enhance the discharge performance of NiF2 cathode through microstructure analysis and electrical perfor-mance tests. By adjusting the addition amount of LiF-LiCl-LiBr eutectic salt,the stable output electri-cal performance of NiF2 anode material under the condition of 500 mA/cm2 was realized.关键词
