FIG. 11 is a schematic representation of a cell for the lithium slurry battery according to the first example of the present disclosure. In addition to the components of cell of the lithium slurry battery shown in FIG. 10, the cell for the lithium slurry battery may further includes an discharge passage 710, a cell inner chamber division plate 715, a sealing cover of the interface 716, and a gas pressure regulating valve 717. In addition, the shell of battery cell 701 in the FIG. 10 is consisting of a top lid of the shell 702 and a lower case of the shell 703. The top lid of the shell 702 and the lower case of the shell 703 are connected by a detachable connecting part to form an inner chamber of the shell. A division plate connecting part 718 is provided on the lower case of the shell 703, and the battery cell inner chamber division plate 715 and the division plate connecting part 718 are connected and fixed by bonding, thereby dividing the inner chamber of the shell into a first inner chamber of the battery cell 713 and a second inner chamber of the battery cell 714 which are independent of each other and are not communicated to each other. The first inner chamber of the battery cell 713 can be filled with dry gas through the gas pressure regulating valve 717, so that the gas pressure P1 in the first inner chamber of the battery cell 713 is higher than the gas pressure P2 in the second inner chamber of the battery cell 714, so as to form a secondary sealing between the battery cell inner chamber division plate 715 and the division plate connecting part 718 of the lower case of the shell 703. The injection interface 706 is in fluid communication with the second inner chamber of the battery cell 714, the discharge interface 708 is in fluid communication with the second inner chamber of the battery cell 714 via the discharge passage 710, and the injection interface 706 and the discharge interface 708 are sealed with the sealing cover of the interface 716.
