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.
