Charge storage configurations

The terms supercapacitor and ultracapacitor are used to describe any double layer or redox capacitor with specific energy and specific power intermediate to batteries and traditional capacitors. Typically, ultracapacitor refers to a device comprised of two carbonaceous electrodes whereas supercapacitor refers to a similar device in which the two carbonaceous electrodes are catalyzed with metal oxides such as Ru02. This chapter will use the term supercapacitor to describe EAP-based capacitors, since that seems to be the most commonly used term for such materials. Another charge storage configuration uses an EAP electrode and a battery-type carbonaceous electrode in what is known as a hybrid device (however, outside of the EAP-based supercapacitor field, hybrid may refer to the combination of a battery electrode such as nickel hydroxide with a carbon electrode) [1]. [Pg.1392]

On the basis of the electrical data collected in those electronic devices, we describe charge transport in the thin-film oligothiophenes (Section 6). In parallel, charge storage configurations in the polythiophenes are studied both in the solid state and in solution. The results for both the oligothiophenes and polythiophenes will be compared and contrasted. In particular, we will... [Pg.312]

In this subsection, we deal with the charge storage configurations on the polythiophenes in the sohds and their anisotropic features. These investigations also serve the purpose of examining whether the charged states share the nature of the charge excitations predicted by theories. [Pg.65]

Spectroscopic studies including ESR, EVS, and UV-Vis. enable the detailed characterization of the charge storage configurations and show that in most cases the bipolarons are the most dominant excitations in the polythiophenes. At the same time, anisotropic features of the charge excitations are quite evident. This has been confirmed by the dichroic IR measurements of the aligned films of the polythiophenes. [Pg.81]
