Abstract

Un élément de type précipitation de sel métallique selon un mode de réalisation de la présente invention comprend : une première électrode de type film ; une seconde électrode en forme de film qui fait face à la première électrode ; une paire de substrats transparents ; des espaceurs ; et un électrolyte. La paire de substrats transparents prennent en sandwich la première électrode et la seconde électrode dans une direction de stratification dans laquelle la première électrode et la seconde électrode se font face. Les espaceurs sont pris en sandwich entre la première électrode et la seconde électrode. Les espaceurs définissent un espace entre la première électrode et la seconde électrode. L'électrolyte est stocké dans l'espace défini par la première électrode, la seconde électrode et les espaceurs. La première électrode, la seconde électrode et les espaceurs sont transparents.
