Beschreibung
Zusammenfassung:	This application describes electrode materials and methods of producing them, the materials containing particles having a core-shell structure, wherein the shell of the core- shell particles comprises a polymer, the polymer being grafted on the surface of the core particle by covalent bonds. Electrodes and electrochemical cells containing these electrode materials are also contemplated, as well as their use. L'invention concerne des matériaux d'électrode et leurs procédés de fabrication, les matériaux contenant des particules à structure cœur-écorce, l'écorce des particules à structure cœur-écorce comprenant un polymère, le polymère étant greffé sur la surface du cœur de la particule par des liaisons covalentes. Des électrodes et des cellules électrochimiques contenant ces matériaux d'électrode sont également décrites, ainsi que leur utilisation.
