Abstract

Abstract: In this work we report an investigation about the influence of the salt concentration on the electrolyte 1-Butyl-1-methylpyrrolidinium tetrafluoroborate (Pyr14 BF4 ) in propylene carbonate (PC) on the electrochemical behaviour of composite electrodes containing poly(2, 2, 6, 6-tetramethylpiperidinyl-N-oxymethacrylate) (PTMA) as the active material. The results of this study show that the salt concentration within the electrolyte has a strong influence on the behaviour of PTMA-based electrodes. The use of concentrated electrolytes displaying a good compromise between conductivities and viscosities appears very favourable for the optimization of the capacity and the reduction of the self-discharge of PTMA electrodes.
