HIGHLY PROCESSABLE LITHIUM CATHODE MATERIAL AND METHOD FOR MAKING

Abstract: techniques for processing lithium-ion cathode active materials, such as cathode active materials comprising lithium-based materials, such as lithium metal oxide materials (e.g., lithium transition metal oxide materials) are provided. the techniques process the lithium-ion cathode active materials after an initial preparation step to remove residual lithium species, such as lithium hydroxide and/or lithium carbonate, present in the lithium-ion cathode active materials. cathode materials comprising low residual lithium species are also described, as well as cathodes and batteries comprising such cathode materials.
