Abstract
An embodiment relates to a method for regenerating the capacity of a used battery by connecting one or both terminals of a used battery and a lithium-supplying electrode to an external power supply unit to supply a lithium inventory to the used battery in order to restore a storage capacity of the used battery, and a device for regenerating the capacity of a used battery for implementing the method.
Claims13
A method for regenerating a capacity of a used battery, comprising:
- partially opening a used battery container;
- placing the opened used battery and a lithium-supplying electrode into an electrolyte solution to create a lithium pathway;
- and
- connecting one or both terminals of the opened used battery and the lithium-supplying electrode to an external power supply unit to supply lithium inventory to the opened used battery, to regenerate the capacity of the opened used battery.
A method for regenerating a capacity of a used battery, comprising:
- connecting the used battery to be regenerated and a lithium-supplying cell to each other via a tube filled with an electrolyte solution therein;
- and
- connecting one or both terminals of the used battery and the lithium-supplying cell to an external power supply unit to supply lithium inventory to the used battery, to regenerate the capacity of the used battery.
A device for regenerating a capacity of a used battery, comprising:
- a container filled with an electrolyte solution into which the used battery to be regenerated is placed;
- a lithium-supplying electrode introduced into the electrolyte solution;
- and
- an external power supply unit that applies voltage or current between a connected terminal of the used battery and the lithium-supplying electrode.
A device for regenerating a capacity of a used battery, comprising:
- a tube filled with an electrolyte solution therein, which is connected to the used battery to be regenerated;
- a lithium-supplying cell connected to one end of the tube filled with electrolyte solution therein;
- and
- an external power supply unit that applies voltage or current between a connected terminal of the used battery and the lithium-supplying cell.
