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. Examples of the lithium transition metal oxide are either one of —LiCOdMeO2, wherein M is either one or both of Mg and Ti, with e

摘要: A particulate precursor compound for manufacturing an aluminum doped lithium transition metal (M)-oxide powder usable as an active positive electrode material in lithium-ion batteries includes a transition metal (M)-hydroxide or (M)-oxyhydroxide core and a non-amorphous aluminum oxide coating layer covering the core. By providing an aluminum dry-coating process where the particulate precursor core compound is mixed with alumina powder in one or more procedures, higher doping levels of aluminum compared to the known prior art may be achieved. The crystal structure of the alumina is maintained during the coating procedures and the core of each mixed transition metal precursor particle is surrounded by a coating layer containing crystalline alumina nano particles. The aluminum concentration in the particulate precursor decreases as the size of the core increases.

摘要: Aluminum dry-coated and heat treated cathode material precursors. A particulate precursor compound for manufacturing an aluminum coatedlithium transition metal (M)-oxide powder usable as an active positive electrode material in lithium-ion batteries includes a transition metal (M)-oxide core and a non-amorphous aluminum oxide coating layercovering the core. By providing a heat treatment process for mixed metal precursors that may be combined with an aluminum dry-coating process, novel aluminum containing precursors that may be used to form high quality nickel based cathode materials are obtained. The aluminum dry-coated and heat treated precursors include particles have, compared to prior art precursors, relatively low impurity levels of carbonate and/or sulfide, and can be produced at lower cost.
