Reintroduction of lithium into recycled battery materials |
| 摘要 |
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. |

1. A method for making a recycled electrode material for an energy-storage device, the method comprising:
harvesting a lithium-deficient electrode material from a recycling or waste stream, the lithium-deficient electrode material comprising lithium iron phosphate; and replenishing at least some lithium in the lithium-deficient electrode material by
suspending the lithium iron phosphate in a non-aqueous solution comprising lithium iodide, andreacting the lithium iron phosphate with the lithium iodide. |
