Embodiment Construction

[0016] figure 1 Aspects of an example embodiment of a method 10 of making a recycled electrode material for an energy storage device are described. It is understood that the example method may be part of a broader method for recycling batteries and / or treating waste streams including battery source waste. Furthermore, the example methods may be part of a broader process for making recycled electrodes for energy storage devices or for making energy storage devices. Thus, in some implementations, one or more actions may be taken before the first stated step and one or more actions may be taken after the last stated step.

[0017] At 12, the lithium-depleted electrode material is collected from a recycle stream or a waste stream. The recycle or waste stream from which the lithium-poor electrode material is collected may be a dedicated battery recycle or waste stream, or more specifically, a lithium battery recycle or waste stream. In addition, the lithium-depleted electrode m...

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.
