Beschreibung
Zusammenfassung:An electrochemical storage cell or battery including as at least one electrode at least one electrically conductive polymer, the polymer being poly (3(2-fluorophenyl)thiophene), poly(3(3-fluorophenyl) thiophene), poly(3(2,4-fluorophenyl) thiophene), poly(3(3,4-difluorophenyl) thiophene), poly(3(3,5-difluorophenyl) thiophene), or poly(3(3,4,5-trifluorophenyl)thiophene). These polymeric electrodes have remarkably high charge capacities, and excellent cycling efficiency. The provision of these polymeric electrode further permits the electrochemical storage cell to be substantially free of metal components, thereby improving handling of the storage cell and obviating safety and environmental concerns associated with alternative secondary battery technology.
