Abstract
Abstract Electrolytic display cell comprising, between two electrodes of appropriate shapes, a liquid electrolyte containing metal ions, wherein said electrolyte comprises ions of a first metal and ions of a second metal, said first and second metals having similar redox potentials. Process for increasing the storage life of the display in a liquid electrolyte cell containing ions of a first metal, wherein ions of a second metal are added, the first and second metals having similar redox potentials.
