[0031] Embodiment 1:

[0032] like Figure 1-Figure 6 As shown, the utility model provides an aluminum-alkali liquid flow battery monomer 1, comprising: a shell, an anode assembly 20 and a cathode assembly 30, wherein a housing cavity 111 is arranged in the shell, and a mounting port 112 communicating with the housing cavity 111 is arranged at one end of the shell, at least a portion of the anode assembly 20 is accommodated in the mounting port 112 and the housing cavity 111, and is suitable for sealing the mounting port 112, and the cathode assembly 30 is arranged at one end of the shell away from the mounting port 112; wherein the anode assembly 20 and the cathode assembly 30 are spaced apart from each other and do not contact each other.

[0033] In some embodiments, a accommodating cavity 111 is formed in the shell, and the shell includes a first side wall and a second side wall in the width direction, the first side wall is formed with a mounting port 112, the mounting port 112 is connected to the accommodating cavity 111, the anode assembly 20 is suitable for connecting with the first side wall, and at least a portion of the anode assembly 20 is accommodated in the mounting port 112 and the accommodating cavity 111, the portion of the anode assembly 20 accommodated in the accommodating cavity 111 is suitable for reacting with the electrolyte to discharge, and the portion of the anode assembly 20 accommodated in the mounting port 112 is suitable for sealing the mounting port 112 to prevent the electrolyte from leaking from the mounting port 112; the second side wall is suitable for connecting the cathode assembly 30, and at least a portion of the cathode assembly 30 is arranged on the side of the second side wall away from the accommodating cavity 111.

[0034] It is worth mentioning that in some existing technologies, the anode assembly and cathode assembly of the aluminum-alkali liquid flow battery cell are both arranged on the first side wall, and the connection relationship between the anode assembly, the cathode assembly and the first side wall is complex. In particular, since the anode sheet and the cathode sheet at least partially overlap in the thickness direction of the shell, the installation and fixing points of the anode sheet and the cathode sheet overlap in the thickness direction of the first side wall, which results in the need to disassemble the anode sheet and the cathode sheet at the same time when the anode sheet or the cathode sheet needs to be replaced, thereby increasing the difficulty of the disassembly and assembly process of the aluminum-alkali liquid flow battery cell.

[0035] It can be understood that in the aluminum-alkali liquid flow battery cell 1 of the present application, the anode assembly 20 and the cathode assembly 30 are respectively arranged on both sides of the shell in the width direction, and the anode assembly 20 and the cathode assembly 30 are respectively connected and fixed to the first side wall and the second side wall. When the anode assembly 20 needs to be replaced, it is only necessary to disassemble the anode assembly 20 and the first side wall accordingly, and avoid disassembling the cathode assembly 30, thereby improving the replacement efficiency of the anode assembly 20; similarly, when the cathode assembly 30 needs to be replaced, it is only necessary to disassemble the cathode assembly 30 and the second side wall accordingly, and avoid disassembling the anode assembly 20, thereby improving the replacement efficiency of the cathode assembly 30.

[0036] Of course, since the anode assembly 20 and the cathode assembly 30 are respectively arranged on both sides of the shell in the width direction, the connection points of the anode assembly 20 and the cathode assembly 30 with the shell do not interfere with each other, which simplifies the structure of the aluminum-alkali liquid flow battery monomer 1 and improves the assembly efficiency of the aluminum-alkali liquid flow battery monomer 1.

[0037] According to the aluminum-alkali liquid flow battery monomer 1 of the utility model, the anode assembly 20 and the cathode assembly 30 are respectively connected to the two side walls of the shell in the width direction, so that the connection points of the anode assembly 20 and the cathode assembly 30 and the shell do not interfere with each other, which simplifies the connection relationship between the anode assembly 20, the cathode assembly 30 and the shell, and improves the matching efficiency of the anode assembly 20, the cathode assembly 30 and the shell, thereby improving the production efficiency of the aluminum-alkali liquid flow battery monomer 1. At the same time, when the anode assembly 20 or the cathode assembly 30 needs to be replaced, it is only necessary to disassemble the anode assembly 20 or the cathode assembly 30 accordingly, avoiding disassembly of the anode assembly 20 and the cathode assembly 30 at the same time, thereby improving the replacement efficiency of the anode assembly 20 or the cathode assembly 30.

[0038] In some embodiments, the aluminum-alkali liquid flow battery cell 1 uses an aluminum-based alloy electrode as the anode (negative electrode), a membrane electrode as the cathode (positive electrode), and a KOH solution as the electrolyte. Aluminum absorbs oxygen from the air and produces a chemical reaction during discharge. Discharge process: Negative electrode: (Al): 4Al-12e - =4Al 3+ ; Positive electrode: (O2): 3O2+6H2O+12e - =12OH - ; Overall reaction formula: 4Al+3O2+6H2O+4KOH=4KAl(OH)4.

The matching relationship between the outer peripheral wall of the sealing boss 222 and the inner peripheral wall of the mounting port 112 is surface contact. Compared with the traditional sealing relationship through a sealing ring (line contact sealing), the present application has a larger sealing surface for the mounting port 112, improves the sealing effect of the mounting port 112, effectively prevents leakage of electrolyte from the mounting port 112, and improves the safety factor of the aluminum-alkali liquid flow battery cell 1.
