Une méthode permettant d’améliorer la durée de vie en cyclage d’un élément électrochimique sodium-ion comprenant une électrode positive à base d’un oxyde de structure cristallographique O3. Cette méthode est fondée sur le blocage de la transformation de la structure cristallographique P3 en la structure cristallographique O3 après que la première transformation de la structure cristallographique O3 en la structure cristallographique P3, qui a lieu lors de la première charge de l’élément, se soit produite. Le maintien de la structure P3 est obtenu en tirant profit d’une part de la propriété de certains métaux de transition de favoriser la formation de la structure cristallographique P3 pour des états de charge proches de l’état complètement déchargé de l’élément et d’autre part du fait que l’irréversibilité créée par un excès d’électrode négative arrête plus tôt la sodiation de l’oxyde au cours de la décharge et ainsi bloque la transformation de la structure cristallographique P3 en la structure cristallographique O3.
