Abstract
Methods for making a recycled or refurbished electrode material for an energy-storage device are provided. One example method comprises harvesting a lithium-deficient electrode material from a recycling or waste stream, and replenishing at least some lithium in the lithium-deficient electrode material. A second example method comprises breeching an enclosure of a cell of an energy storage device, replenishing at least some lithium in a lithium-deficient electrode material of the cell, and sealing the enclosure of the cell.
