Dendrite-inhibiting electrolytic solution and rechargeable aqueous zinc--halogen cell containing the solution. [Zn/Br]
A dendrite-inhibiting electrolytic solution and rechargeable aqueous zinc--halogen cell containing the solution are described. The electrolytic solution contains a zinc compound, a non-ionic surfactant additive of oxaalkyl or polyoxaalkyl perfluoroalkane sulfonamide in an amount of from 0.001 to 10 weight percent of the solution, and an organic solubilizer in an amount from 5 to 50 weight percent of the solution. The cell includes a casing, a pair of spaced-apart porous electrode substrates in the casing, an ion exchange membrane separator between the electrode substrates defining a positive and a negative electrode compartment, an electrolytic solution containing a zinc compound in the positive compartment, and the above electrolytic solution containing the additive and the solubilizer in the negative zinc electrode compartment. 2 figures.
