| Thermal batteries are heat-activated batteries commonly employed as internal power sources for various military weapons due to their excellent storage stability, discharge reliability, and mechanical robustness. To suit the present diverse needs of use, the development of thermal batteries realizes miniaturization while improving electrochemical performance. High-performance thermal batteries depend mainly on the development of the cathode, modification of existing cathode materials, and development of new cathode materials are the main methods to improve the performance of thermal batteries. This review provides a comprehensive account of recent studies on sulfide, chloride, and fluoride thermal battery cathode materials and a thorough assessment of their material properties and discharge performance. Finally, based on the specific application situations of thermal batteries, the future development direction of their cathode materials is summarized and forecasted in terms of thermal stability, discharge voltage, and conductivity. |
