FIG. 12 is a schematic representation of a liquid-exchangeable lithium slurry battery module according to the first example of the present disclosure. The liquid-exchangeable lithium slurry battery module 8 includes a cell can 801 and a plurality of cells of the lithium slurry battery 7. The cell can 801 includes a top lid of the cell can 802 and a lower housing of the cell can 803, and the top lid of the cell can 802 and the lower housing of the cell can 803 form an inner chamber of the cell can. A detachable connecting part 9 is provided on the top lid of the cell can 802 and the lower housing of the cell can 803, and the top lid of the cell can 802 and the lower housing of the cell can 803 can be easily detached and reinstalled by the bolt connection of the detachable connecting part 9. The cell of the lithium slurry battery 7 is disposed in the inner chamber of the cell can, and the cell of the lithium slurry battery 7 is provided with a positive terminal 704, a negative terminal 705, an injection interface 706, and a discharge interface 708. Therein, the injection interface 706 and the discharge interface 708 can be quickly connected with or disconnected from the interface of the pump and the liquid injection device. In addition, the injection interface 706 and the discharge interface 708 automatically open when the injection interface 706 and the discharge interface 708 engage with the interface of the pump or the liquid-injecting device, and the injection interface 706 and the discharge interface 708 automatically close after the connection is broken.
