Suppressing self-discharge of Li-B/CoS₂ thermal batteries by using a carbon-coated CoS₂ cathode.

ABSTRACT: Thermal batteries with molten salt electrolytes are used for many military applications, primarily as power sources for guided missiles. The Li-B/CoS₂ couple is designed for high-power, high-voltage thermal batteries. However, their capacity and safe properties are influenced by acute self-discharge that results from the dissolved lithium anode in molten salt electrolytes. To solve those problems, in this paper, carbon coated CoS₂ was prepared by pyrolysis reaction of sucrose at 400 °C. The carbon coating as a physical barrier can protect CoS₂ particles from damage by dissolved lithium and reduce the self-discharge reaction. Therefore, both the discharge efficiency and safety of Li-B/CoS₂ thermal batteries are increased remarkably. Discharge resu
