Abstract
First generation super dielectric materials (SDMs), discovered in our lab, are multi-material mixtures with dielectric constants greater than 105, composed of a porous electrically insulating powders filled with a polarizable, ion-containing liquid. This project is focused on optimizing a more practical second generation SDM (TSDM). These are anodic titania nanotube arrays filled with concentrated aqueous salt solutions. In our lab ‘early’ TSDM (prior to project initiation) were formed with dielectric constants greater than 107, a maximum operating voltage of greater than 2 volts and remarkable energy density, greater than 200 J/cm3 of dielectric, a value that surpasses the highest previously reported for dielectric based capacitors by approximately one order of magnitude.
