Abstract[English]
The present invention relates to the field of a sodium-ion battery positive electrode and its method of preparation. The present invention provides a modified binder to prepare the positive electrode slurry with improved dispersibility and adhesion properties to strongly adhere to a current collector, thereby maintaining excellent electrode properties. The positive electrode slurry with better adhesivity /wettability ensures the strong and uniform adhesion of the electrode with the current collector, thereby providing excellent diffusion path which in turn results in better storage performance.[French]
La présente invention concerne le domaine d'une électrode positive de batterie sodium-ion et son procédé de préparation. La présente invention propose un liant modifié pour préparer la suspension d'électrode positive avec une dispersibilité et des propriétés d'adhérence améliorées pour adhérer fortement à un collecteur de courant, ce qui permet de maintenir d'excellentes propriétés d'électrode. La bouillie d'électrode positive possédant une meilleure adhésivité/mouillabilité assure l'adhérence forte et uniforme de l'électrode avec le collecteur de courant, ce qui permet d'obtenir un excellent trajet de diffusion qui, à son tour, entraîne une meilleure performance de stockage.
