Abstract
This study explored the impact of the materials employed, particularly electrode material, on the performance of Novel Paradigm Supercapacitors (NPS). The main experimental focus was on the impacts of changing the identity of the electrode materials in Novel Paradigm Supercapacitors employing Distilled Deionized water (DI) or DI with 3.5 wt % dissolved NaCl. In sum, it was determined that i) some metals too easily corrode in this application (e.g., silver and lead) to be functional for more than a few hours, ii) titanium is an excellent electrode material that corrodes very slowly and the corrosion layer has an impact on performance, and iii) conductive carbon of any type is superior to all other materials in terms of net energy storage capability. The study also served the purpose of testing the Super Dielectric Material Theory (SDM-Theory). The main thrust of the "theory" component was to test the general SDM model of dielectrics against the standard model using appropriately designed experiments, specifically, experiments designed to measure the impact of dielectric material “outside” the volume between the electrodes. Traditional theory indicates the material outside the capacitor has no possible impact, whereas SDM theory says it can have a very significant impact. Results were only consistent with SDM theory.
