The invention relates to an electrolyte solution suitable for use in a zinc-bromine battery, comprising zinc bromide and a mixture of at least two complexing agents selected from the group consisting of 1-R-2-methyl pyridinium bromide and 1-R-3-methyl pyridinium bromide salts, wherein each of Rand Ris independently an alkyl group having not less than five carbon atoms.

Additives for a flow battery

The present invention provides devices for real-time, continuous, detection of spoilage and freshness of food products.

Devices for monitoring food freshness and methods of using same

The invention relates to a method of operating a zinc-bromine battery, especially at a high temperature, comprising adding 1-n-butyl-2-methyl-pyridinium bromide to the electrolyte of said battery, and charging or discharging said cell. Also provided is the use of 1-n-butyl-2-methyl-pyridinium bromide as an additive in a zinc-bromine battery operating at a temperature above 30&#xb0; C., and an aqueous concentrate with high content of 1-n-butyl-2-methyl-pyridinium bromide.

Additive for a flow battery

The invention relates to the use of 1-alkyl-2-alkyl pyridinium halide (e.g., 1-ethyl-2-methyl pyridinium bromide), 1-alkyl-3-alkyl pyridinium halide (e.g., 1-ethyl-3-methyl pyridinium bromide) or 1-alkyl-3-alkyl imidazolium halide (e.g., 1-butyl 3-methyl imidazolium bromide) as additives in an electrolyte used in hydrogen/bromine cells, for complexing the elemental bromine formed in such cells. The invention also provides an electrolyte comprising aqueous hydrogen bromide and said additives, and processes for operating an electrochemical flow cell selected from the group consisting of hydrogen/bromine or vanadium/bromine cells.

Additives for hydrogen/bromine cells

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.
