Abstract
An electrolyte is disclosed which can be used in a variety of electrochemical cells and rechargeable accumulators. The electrolyte solution contains a complexing agent which reduces electrode solubility, combats dendrite formation, improves electrolyte conductivity and low temperature operation. The complexing agent additive described can be used with various electrolytes and existing cell types to advantage. Aspects of this invention are applicable to Ni-Cd, Ag-Cd, Ag-Zn, Ni-Fe, Ni-Zn, and like cells.
Claims9
In a current producing cell or an accumulator with electrodes comprising active materials and a single dilute aqueous electrolyte conducting ions between the electrodes, wherein the improvement comprises up to 4 grams, per 100 ml of the dilute electrolyte, of a potassium or sodium ferro- or ferricyanide additive increasing the ion conductivity of the electrolyte and reducing the electrode solubility.
