The invention relates to the use of nitrogen-containing compounds belonging to the classes of N-alkyl pyridinium halide, N-alkyl-2-alkyl pyridinium halide and 1-alkyl-3-alkyl imidazolium halide, as additives in electrolyte solutions for zinc bromine membraneless flow cells. The invention also provides electrolyte solutions comprising such additives and processes for operating said cells.

Additives for zinc-bromine membraneless flow cells

The invention relates to the use of at least one 1-alkyl-3-alkyl-pyridinium halide, in particular 1-alkyl-3-methyl-pyridinium bromide, as an additive in bromine-generating electrochemical cells, such as zinc/bromine cells. Processes for preparing 1-alkyl-3-methyl-pyridinium bromide and concentrated aqueous solutions comprising same for use as additives in the aforementioned cells, are also disclosed.

Processes for preparing 1-alkyl-3-alkyl-pyridinium bromide and uses thereof as additives in electrochemical cells

A method for generating molecular bromine in bromide-containing electrolyte solution suitable for use in a metal bromine cell, involves chemically oxidizing bromide (Br) in the electrolyte solution in an acidic environment, to produce the molecular bromine.
