Abstract
(EN)
Improved methods for preparing lithium transition metal oxide particulate such as lithium nickel metal cobalt oxide ("NMC") for use in lithium batteries and other applications are disclosed. The lithium transition metal oxide particulate is prepared from appropriate transition metal oxide and Li compound precursors mainly using dry, solid state processes including dry impact milling and heating. Further, novel precursor particulates and novel methods for preparing precursor particles for this and other applications are disclosed.

L'invention concerne des procédés améliorés de préparation de matière particulaire d'oxyde de métal de transition au lithium, tel que l'oxyde de lithium-nickel-manganèse-cobalt (NMC), destinée à être utilisée dans des batteries au lithium et d'autres applications. La matière particulaire selon l'invention est préparée à partir de précurseurs de composé de Li et d'oxyde de métal de transition appropriés, principalement par des procédés à l'état solide et sec, notamment le chauffage et broyage par impact à sec. L'invention concerne également de nouvelles matières particulaires de précurseurs et de nouveaux procédés de préparation de matière particulaire de précurseurs pour ladite application et d'autres.
