Title (EN) GRAPHENE-COATED METAL OXIDE SPINEL CATHODES
(FR) CATHODES DE SPINELLE D'OXYDE MÉTALLIQUE REVÊTUES DE GRAPHÈNE
Abstract: front page image
(EN) Disclosed herein are graphene-coated lithium manganese oxide spinels cathodes for high-performance batteries Li-ion batteries and methods for making thereof. A single-layer graphene coating is shown to significantly reduce manganese loss in the cathodes while concurrently promoting the formation of a well-defined solid electrolyte interphase layer.
(FR) La présente invention concerne des cathodes de spinelle d'oxyde de lithium et de manganèse revêtues de graphène pour batteries performantes et batteries Lithium-ion et leurs procédés de fabrication. Il s'avère qu'un revêtement de graphène monocouche réduit considérablement la perte de manganèse dans les cathodes, tout en favorisant la formation d'une couche d'interphase à électrolyte solide bien définie.
