Abstract

La présente invention concerne : une électrode comprenant une couche de graphène, pour améliorer les propriétés d'adhérence entre une couche d'agrégats de nanoparticules actives d'électrode auto-assemblée et un collecteur ; une batterie secondaire comprenant celle-ci ; un condensateur électrochimique comprenant celle-ci ; et un procédé de fabrication de celle-ci. Plus particulièrement, la couche de graphène recouvre la couche d'agrégats de nanoparticules actives d'électrode auto-assemblée, et la couche de graphène et la couche d'agrégats de nanoparticules actives d'électrode forment un multicouche alterné de telle sorte qu'un transfert rapide d'électrons est atteint à travers la couche de graphène et des ions lithium peuvent se déplacer rapidement à travers les espaces vides entre les agrégats. Ainsi, une batterie mince appropriée pour chargement et déchargement rapide peut être réalisée. En particulier, une stabilité mécanique peut être augmentée pour fournir de bonnes caractéristiques durables.
