Abstract
Examples are disclosed of methods to recycle coated positive-electrode material of a lithium-ion battery. One example provides a method including relithiating the coated positive-electrode material in a solution comprising lithium ions, and after relithiating, separating the coated positive-electrode material from the solution. In some examples, coated positive-electrode materials may be reinstated using lower process temperatures than uncoated positive-electrode material.
