Title (EN) CATHODE MATERIALS FOR LITHIUM BATTERIES
(FR) MATÉRIAUX DE CATHODE POUR BATTERIES AU LITHIUM
Abstract: front page image
(EN)Described are cathode materials for lithium batteries. Better cathode materials may be produced by mixing at least two compounds and a binder additive. The first compound includes one or more salts of lithium metal phosphorous while the second compound includes one or more lithium transition metal oxides. In other instances, a conductive additive may also be incorporated. The cathode materials so produced exhibit enhanced electrical properties and thermal stability.
(FR)L'invention porte sur des matériaux de cathode pour batteries au lithium. De meilleurs matériaux de cathode peuvent être produits par mélange d'au moins deux composés et d'un additif liant. Le premier composé comprend un ou plusieurs sels de lithium-métal-phosphore tandis que le second composé comprend un ou plusieurs oxydes de lithium-métal de transition. Dans d'autres cas, un additif conducteur peut également être incorporé. Les matériaux de cathode ainsi produits présentent des propriétés électriques et une stabilité thermique améliorées.
