Lithium ion battery electrodes including graphenic carbon particles are disclosed. Lithium ion batteries containing such electrodes are also disclosed. The graphenic carbon particles may be used in cathodes of such batteries by depositing a graphenic carbon particle-containing coating of a conductive substrate such as a metal foil The use of graphenic carbon particles in the cathodes results in improved performance of the lithium ion batteries.
Abstract:
Disclosed is a method of recovering inorganic pigment such as TiO2 from a coating composition that includes liquid, an organic component, and an inorganic component. The coating composition is thermally treated to remove at least a portion of the organic component and yield an inorganic pigment composition having a higher concentration of the inorganic pigment (TiO2) than in the original coating composition.
