摘要本论文使用80μm和200μmAl/Ni两种厚度的纳米复合薄膜替代传统的烟火药剂作为热源制作了热电池并开展了一系列实验。实验用不同数量及两种厚度的纳米含能薄膜制作和装配了三单元及四单元电堆，并对其在530mA恒定电流下进行放电性能测试。根据实验得到的电压时间曲线计算得到热电池内阻随时间变化。
实验结果表明，用Al/Ni含能薄膜作为热源装配热电池的方案可行且有一定的优势。实验制作的热电池样机放电实验表明热电池峰值电压为5.72V，激活时间为0.24S，工作时间达44S，结果较为满意，且与传统热电池放电性能相比有一定优越性。68580

Abstract
This paper describes and discusses a series of experiments in which aluminum-nickel nanofoil materials were used as the heat source for thermal battery.Different numbers and different kinds of Al-Ni nanofoils (80μm and 200μm) was used as the heat source to build 3-cell and several 4-cell thermal batteries prototypes. Then these batteries were discharged at constant current of 530mA and monitored for their electrical performances.Their internal resistance was also determined from calculation.
The results were carefully compared and thoroughly discussed. And it came to the conclusion that use of nanofoil as a new source of heat in thermal batteries is feasible and advantageous— the rise time of the prototype was 0.24s,the highest voltage was 5.72v and its runtime was 44s,which was satifactory compared to the traditional pressed-pellet thermal batteries.
