Abstract[English]
The present invention relates to the method for preparing the electrode active material slurry by varying the constituent ratios. The invention provides a method for preparing the negative electrode slurry by combining a clustered complex consisting of an active material (AM), a binder and a conductive material in the solvent like NMP, Deionized water. The improved and optimized rheology and wettability of the slurry, resulting in more uniform coating and better adhesion on the current collector. The invention provides anode fabrication in the production of high-performance sodium-ion batteries, offering a practical and cost-effective solution for energy storage, especially the plateau capacity up to 0.2 V during charging, the charge-discharge efficiency and the capacity retention at normal temperatures.[French]
La présente invention concerne le procédé de préparation de la suspension de matériau actif d'électrode par variation des rapports constitutifs. L'invention concerne un procédé de préparation de la suspension d'électrode négative par combinaison d'un complexe groupé constitué d'un matériau actif (MA), d'un liant et d'un matériau conducteur dans le solvant tel que du NMP, de l'eau désionisée. La rhéologie et la mouillabilité améliorées et optimisées de la suspension permettent d'obtenir un revêtement plus uniforme et une meilleure adhérence sur le collecteur de courant. L'invention fournit une fabrication d'anode dans la production de batteries sodium-ion haute performance, offrant une solution pratique et économique pour le stockage d'énergie, en particulier la capacité de plateau, jusqu'à 0,2 V pendant la charge, l'efficacité de charge-décharge et la rétention de capacité à des températures normales.
