Electronically conducting polymers and activated carbon: Electrode materials in supercapacitor technology

Abstract

Supercapacitors are now attracting much attention as battery‐complementary devices for applications requiring high operating power levels, such as in electric vehicle technology. Two types of supercapacitors with different modes of energy storage are currently under study: the double‐layer, and the redox. Electronically conducting polymers represent an interesting class of electro‐active materials for redox supercapacitors and can be applied in different configurations. Performance data for new and conventional devices are presented and compared to those of a double‐layer capacitor with activated carbon electrodes.

Non-oxidative thermal degradation of poly(ethylene oxide): kinetic and thermoanalytical study

“…PEO is among the first and most studied polymers for polymer solid electrolytes that are applied in solid-state batteries [3], capacitors [4] and electrochromic devices [5]. However, PEO (i) possesses appreciable ionic conduction only above 65 8C and (ii) can be processed and applied at higher temperatures, where partial decomposition may already occur [6].…”

Step-scan alternating DSC study of melting and crystallisation in poly(ethylene oxide)

“…PEO is among the first and most studied polymers for polymer solid electrolytes that are applied in solid-state batteries [3], capacitors [4] and electrochromic devices [5,6]. A relatively new application that is considered as a very promising one concerns PEO as a thermal energy storage material since it has large heat of fusion and a congruent melting behaviour [7,8].…”

Solid polymer electrolytes. IV. Preparation and characterization of novel crosslinked epoxy‐siloxane polymer complexes as polymer electrolytes

“…Intensive interest has been focused on the materials of solid polymer electrolytes (SPEs) because of their applications in solid‐state batteries,1 capacitors,2, 3 and electrochromic devices 4. These polymer electrolyte materials are characterized by conductivity behavior that is highly dependent on the local structure and is influenced by crystallization and ion association.…”
