Preparation and Properties of FeS2 Thin Film Cathode for Thermal Batteries
The FeS2 thin film cathode for thermal batteries was prepared by 3D printing technology,and the effects of different electrolyte types,discharge test temperature and cathode thickness parameters on the discharge characteristics of single battery were investigated.The experimental results showed that the cathode of the film prepared by 3D printing technology had higher specific capacity and better stability.When testing the thin film cathode,using the all lithium LiCl-LiBr-LiF electrolyte cellers had the best discharge performance,and the initial voltage reached 2.19V.Up to 1.5 V,the battery specific capacity reached 688.5 mA·h·g-1.
