Title (EN) HYBRID LITHIUM ANODE ELECTRODE LAYER AND LITHIUM-ION BATTERY CONTAINING SAME
(FR) COUCHE D'ÉLECTRODE D'ANODE AU LITHIUM HYBRIDE ET BATTERIE AU LITHIUM-ION CONTENANT CETTE DERNIÈRE
Abstract:
(EN) Provided is a lithium ion battery that exhibits a significantly improved specific capacity and much longer charge-discharge cycle life. In one preferred embodiment, the battery comprises a cathode, an anode, an electrolyte in ionic contact with both the cathode and the anode, and an optional separator disposed between the cathode and the anode, wherein, prior to the battery being assembled, the anode comprises (a) an anode active material layer composed of fine particles of a first anode active material having an average size from 1 nm to 10 μm, an optional conductive additive, and an optional binder that bonds the fine particles and the conductive additive together to form the anode active material layer having structural integrity and (b) a layer of lithium metal or lithium metal alloy having greater than 80% by weight of lithium therein, wherein the layer of lithium metal or lithium metal alloy is in physical contact with the anode active material layer.
(FR) L'invention concerne une batterie au lithium-ion qui présente une capacité spécifique considérablement améliorée et une durée de vie en cyclage de charge-décharge beaucoup plus longue. Dans un mode de réalisation préféré, la batterie comprend une cathode, une anode, un électrolyte en contact ionique avec la cathode et l'anode, et un séparateur facultatif disposé entre la cathode et l'anode, avant assemblage de la batterie, l'anode comprenant (a) une couche de matériau actif d'anode composée de fines particules d'un premier matériau actif d'anode d'une taille moyenne comprise entre 1 nm et 10 µm, un additif conducteur facultatif, et un liant facultatif qui lie ensemble les particules fines et l'additif conducteur de manière à former la couche de matériau actif d'anode à intégrité structurale, et (b) une couche de métal de lithium ou d'alliage de métal de lithium renfermant plus de 80 % en poids de lithium, la couche de métal de lithium ou d'alliage de métal de lithium étant en contact physique avec la couche de matériau actif d'anode.
