Study of Bromine Complexing Agents in ZBFBs Zinc–bromine redox flow batteries (ZBFBs) should use a bromine complexing agent (BCA) as an additive for bromine stability, as shown below.
While zinc bromine flow batteries offer a plethora of benefits, they do come with certain challenges. These include lower energy density compared to lithium-ion batteries, lower round-trip efficiency, and the need for periodic full discharges to prevent the formation of zinc dendrites, which could puncture the separator.
The model of zinc bromine battery can agree well with experiment. The more curved channel design will decrease charging voltage, but increase discharging voltage. The multiple curved flow channels can improve the voltage efficiency. 1. Introduction
In no-membrane zinc flow batteries (NMZFBs) or iterations of the ZBFB that does not use a membrane to separate the positive and negative electrolytes, the electrolytes are separated by a porous spacer that allows ions to pass through but prevents the two electrolytes from mixing.
Pirrolidinium-Based BCAs Pyrrolidinium-based compounds are the other most studied ILs for use as BCAs in zinc–bromine flow batteries, due to their ability to form an effective complex with the free bromine generated during the battery-charging process.
