Abstract[English]
A conductive composition for a secondary battery, the conductive composition comprises a copolymer, carbon nanotubes (CNTs), and an aqueous solvent. The copolymer comprises a structural unit (a), a structural unit (b), and a structural unit (c), and has excellent adhesion to the surface of the CNTs as well as a high affinity for the aqueous solvent. As a result, the CNTs can be dispersed more uniformly in the aqueous solvent of the conductive composition, and the conductive composition can remain stable even after a significant period of time. Therefore, the CNTs can be more easily handled and adapted for use in various application. An electrode slurries comprising an electrode active material. Battery cells comprising an electrode prepared using such the electrode slurry exhibit impressive electrochemical performances.[French]
Composition conductrice pour une batterie secondaire, la composition conductrice comprend un copolymère, des nanotubes de carbone (CNT) et un solvant aqueux. Le copolymère comprend une unité structurale (a), une unité structurale (b) et une unité structurale (c), et présente une excellente adhérence à la surface des CNT ainsi qu'une affinité élevée pour le solvant aqueux. Par conséquent, les CNT peuvent être dispersés plus uniformément dans le solvant aqueux de la composition conductrice, et la composition conductrice peut rester stable même après une importante période de temps. Par conséquent, les CNT peuvent être facilement manipulés et adaptés à une utilisation dans diverses applications. L'invention concerne également des suspensions d'électrode comprenant un matériau actif d'électrode. Des éléments de batterie comprenant une électrode préparée à l'aide de ladite suspension d'électrode présentent des performances électrochimiques impressionnantes.
