Rechargeable galvanic cell

Patent ·
OSTI ID:7365634
; ;
A rechargeable galvanic cell is described which consists of zinc anode, a cathode, and an electrolyte. The electrolyte comprises an aqueous alkaline solution containing alkali metal zincate and a polycation selected from the group consisting of ionen-type polycations and pendant-type polycations in an amount sufficient to suppress the formation of zinc dendrites on the zinc anode during cell charge. The ionen-type polycation has quaternary nitrogen included in the main chain of the molecule, and the pendant-type polycation has quaternary nitrogen included in the side chain of the molecule.
