摘要: A lithium transition metal oxide powder for use in a rechargeable battery is disclosed, where the surface of the primary particles of said powder is coated with a first inner and a second outer layer, the second outer layer comprising a fluorine-containing polymer, and the first inner layer consisting of a reaction product of the fluorine-containing polymer and the primary particle surface. An example of this reaction product is LiF, where the lithium originates from the primary particles surface. Also as an example, the fluorine-containing polymer is either one of PVDF, PVDF-HFP or PTFE.
