The performance of a polymer redox supercapacitor based on poly(dithieno[3,4-b : 3',4'-d] thiophene) in liquid and in polymer gel electrolyte was tested for capacity, energy density, power density and self-discharge. The results are very promising and demonstrate the viability of a symmetric superca

โฆ Synopsis
Electroceramics are advanced materials whose properties and applications depend on the close control of structure, composition, ceramic texture, dopants and dopant (or defect) distribution. Impedance spectroscopy is a powerful technique for unravelling the complexities of such materials, which functions by utilizing the different frequency dependences of the constituent components for their separation. Thus, electrical inhomogeneities in ceramic electrolytes, electrode/electrolyte interfaces, surface layers on glasses, ferroelectricity, positive temperature coefficient of resistance behavior and even ferrimagnetism can all be probed, successfully, using this technique.
