Also note that static Zinc bromine batteries without any complexing agents - like the one shown in Robert's zinc bromine battery video outside the members channel - are of no interest to me as the self-discharge rate because of bromine diffusion is way too high, plus having any presence of pure elemental bromine at my house is not acceptable ...
2.1 Static (Non-flow) Configurations. Static non-flow zinc–bromine batteries are rechargeable batteries that do not require flowing electrolytes and therefore do not need a complex flow system as shown in Fig. 1a. Compared to current alternatives, this makes them more straightforward and more cost-effective, with lower maintenance requirements.
