摘　　要：研究了单体电池厚度、集流片厚度、热量输入对FeS2/KCl-LiCl/LiSi体系热电池激活时间的影响。结果表明:对于一定体系热电池而言,其激活过程是一个非稳态热传导过程,遵从热传导方程;单体电池和集流片厚度越厚,激活时间越长;热量输入越高激活时间越短,但受正极材料受热分解所限,热量输入应控制在合理范围内。The effects of the following factors on the activation time in the FeS2/KCI-LiCI/LiSi thermal battery were studied, such as the thickness of unit cell, thickness of current collector and quality of heat-source input. The results indicate that the activation process is an unsteady-state heat transfer process in a given system thermal battery, complying with the heat transfer equation. With the thickness increase of unit cell and current collector, the activation time increases. In contrast, with the quality increase of heat-source input, the activation time decreases. However, restricted by the decomposition of cathode material, the quality of heat-source input should be controlled in a reasonable range.
