Reproducing Zn-Br flow batteries using Sodium Sulfamate

A recent Chinese Nature paper showed how Sodium sulfamate can be used in Zn-Br batteries to sequester active Br2 into an N-bromosulfamate that is much less aggressive, much more water soluble and even more easily electrochemically reversible than elemental bromine. I also wrote a recent post discussing the potential use of nicotinamide to achieve this (plot twist, it doesn't work as the nicotinamide Zn complex is not very soluble). In today's post I want to share with you my attempts at […]
