Abstract
The current trend of military forces worldwide is an increasing dependence on electrical power, and the Canadian Forces is no exception. Current technology, such as chemical sensors, radios, and portable computers, as well as rapidly emerging weaponry such as electromagnetic guns and directed energy weapons, demand increasingly sophisticated provision of electrical energy. Supercapacitors, for example, are ideally suited to supply large pulses of energy, and it is within the DRDC Technology Investment Fund project on supercapacitor materials that the current research has been undertaken. This document reports the work of a summer student who studied two fundamental aspects of novel energy provision. First, a comparison of the low temperature performance of two different types of supercapacitor separator represents this lab’s initial investigation into this niche area. It was found that a fixed pore separator outperforms a proton exchange membrane at low temperatures. Second, work with nanostructured polypyrrole composites builds on our earlier work in this interesting material, one which has numerous potential applications, including energy storage. Several concept structures are reported, including an all-polymer wire.
