Title (EN) CORE-SHELL-COMPOSITE PARTICLES FOR LITHIUM-ION BATTERIES
(FR) PARTICULES COMPOSITES COEUR-ÉCORCE POUR BATTERIES LITHIUM-ION
(DE) KERN-SCHALE-KOMPOSITPARTIKEL FÜR LITHIUM-IONEN-BATTERIEN
Abstract:
(EN) The invention relates to lithium-ion batteries, having anodes based on an anode material containing core-shell-composite particles, characterized in that the core of the core-shell-composite particles is a porous, carbon-based matrix containing silicon particles and the shell of the core-shell-composite particles is non-porous and obtainable through carbonization of one or more carbon precursors and the anode material of the completely charged lithium-ion battery is lithiated only in part.
(FR) La présente invention concerne des batteries lithium-ion dont les anodes font appel à un matériau d'anode contenant des particules composites coeur-écorce. L’invention est caractérisée en ce que le coeur des particules composites coeur-écorce est une matrice à base de carbone poreuse, contenant des particules de silicium, et l'écorce des particules composites coeur-écorce est non poreuse et peut être obtenue par carbonisation d'un ou de plusieurs précurseurs de carbone, et le matériau d’anode de la batterie lithium-ion complètement chargée n'est que partiellement lithiée.
(DE) Gegenstand der vorliegenden Erfindung sind Lithium-Ionen-Batterien, deren Anoden auf einem Kern-Schale-Kompositpartikel enthaltenden Anodenmaterial basieren, dadurch gekennzeichnet, dass der Kern der Kern-Schale-Kompositpartikel eine Siliciumpartikel enthaltende, poröse, Kohlenstoff-basierte Matrix ist und die Schale der Kern-Schale-Kompositpartikel unporös ist und durch Carbonisierung von einem oder mehreren Kohlenstoff-Precursoren erhältlich ist und das Anodenmaterial der vollständig geladenen Lithium-Ionen-Batterie nur teilweise lithiiert ist.
