| Zusammenfassung: | The invention relates to a core-shell composite sulfide material. The inner core of the core-shell composite sulfide material is iron disulfide, and the outer shell is cobalt disulfide. After the core-shell structure is formed, the heat stability of the material is remarkably improved; compared with pure iron disulfide, the thermal decomposition temperature is increased from 550 DEG C to 580-640 DEG C. Meanwhile, the conductivity of the material is remarkably improved; and compared with pure iron disulfide, the conductivity is multiplied. The core-shell composite material designed and preparedin the invention can be used as a positive electrode material of a thermal battery. When being used as the positive electrode material of the thermal battery, the product designed and provided by theinvention has the advantages of high thermal stability, electrochemical performance, chemical stability, effective capacity, power and the like.
