(FR) ANODES, LEURS PROCÉDÉS DE PRÉPARATION, ET BATTERIES AU LITHIUM-ION
Abstract:
(EN) An anode, which includes a current collector and an anode material stack coated on the current collector, the anode material stack includes an anode active material layer, which includes porous carbon material and a first binder, and the porous carbon material is mixed with the binder. The anode material stack further includes a carbon intermediate layer sandwiched between the current collector and the anode active material layer. It also provides a method for preparing the anode. Further, it provides a lithium ion battery including the anode above.
(FR) La présente invention concerne une anode, qui comprend un collecteur de courant et un empilement de matériau d'anode revêtu sur le collecteur de courant, l'empilement de matériau d'anode comprend une couche de matériau actif d'anode, qui comprend un matériau carboné poreux et un premier liant, et le matériau carboné poreux est mélangé avec le liant. L'empilement de matériaux d'anode comprend en outre une couche intermédiaire de carbone prise en sandwich entre le collecteur de courant et la couche de matériau actif d'anode. L'invention concerne également un procédé de préparation de l'anode. En outre, l'invention concerne une batterie au lithium-ion comprenant l'anode susmentionnée.
