Spectroscopic evidence for Br2 release during electrochemical reduction of quaternary ammonium polybromides.

Abstract

Understanding how polybromides deliver electroactive bromine is important for exploiting their high bromine-storage capacity. Higher-order polybromides act as dynamic Br2 reservoirs rather than passive stores. During discharge, conversion into lower-order species releases Br2, generating Br- and promoting Br3- formation through a coupled Br2/Br3- reduction pathway.
