摘要：
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.
