A thermal battery is characterized by an internal pyrotechnic heat source reaction melts the electrolyte to activate the battery. The heat sources that have been used in thermal batteries are heat pellets, which are ignited by a heat paper in contact with each pellet. The high heat transfer by heat pellets causes thermal decomposition at the solid electrolytes are melted. The ignition of the heat pellets was affected by combustion properties of the heat paper. However, the combustion of the heat paper is a fundamental problem which requires a solution. In this paper, we prepared Zr/BaCrO4 heat paper with binder and investigated the characteristics of heat papers such as calorimetric value and fabricated. Results show that during combustion, the calorimetric value of Zr/BaCrO4 with 3 wt.% of nitrocellulose were increased. And the tape casting process includes depositing the slip on the carrier substrate in sheet form. In some embodiments, the pore metal sheet formed during the casting process can have any desirable shape and size suitable for the operation. Therefore, the heat paper prepared were stably ignited, burned and the combustion becomes efficient.
