FIG. 13 is a schematic representation of a liquid-exchangeable lithium slurry battery module according to the second example of the present disclosure. The liquid-exchangeable lithium slurry battery module 8 includes a cell can 801, a plurality of cells of the lithium slurry battery 7, and an integral liquid-exchanging system 812. 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. The top lid of the cell can 802 and the lower housing of the cell can 803 are fixedly connected by welding. There is also a main injection port 805, a valve of the main injection port 806, a main discharge port 807, and a valve of the main discharge port 808 provided on the top lid of the cell can. 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, a flow valve of the injection interface 707, a discharge interface 708, and a flow valve of the discharge interface 709. The integral liquid-exchanging system 812 includes a main injection pipe 813, a branch injection pipe 814, a main discharge pipe 815, and a branch discharge pipe 816. Wherein, the main injection port 805 on the top lid of the cell can 802 is connected to the main injection pipe 813 of the integral liquid-exchanging system 812. The main injection pipe 813 is connected to each branch injection pipe 814, and the branch injection pipes 814 are connected to the injection interfaces 706 of the cells of the lithium slurry battery 7. The main discharge port 807 on the top lid of the cell can 802 is connected to the main discharge pipe 815 of the integral liquid-exchanging system 812. The main discharge pipe 815 is connected to each of the branch discharge pipes 816, which are connected to the discharge interface 708 of the cell of the lithium slurry battery 7. Wherein, the valve of the main injection port valve 806 and valve of the main discharge port 808 can control the total amount of liquid or the total amount of gas entering and exiting the liquid-exchangeable lithium slurry battery module. The flow valve of the injection interface 707 and the flow valve of the discharge interface 709 can control the amount of liquid or gas entering and discharging a single lithium slurry battery cell 7.
