As shown in fig. 1 to 10, a metal-air battery 1 is a battery structure that releases electric energy by a chemical reaction of metal and air. For example, the metal-air battery 1 may release electric energy by using a chemical reaction of metal aluminum and oxygen in the air in an electrolyte. Specifically, the metal-air battery 1 includes: an air electrode 11, a metal electrode 13 and an electrolyte. The air electrode 11, which is the positive electrode of the metal-air battery 1, consumes oxygen in the air and converts the oxygen into hydroxyl in the electrolyte, and the metal electrode 13 is made of metal aluminum, and the metal aluminum and the hydroxyl in the electrolyte react chemically to release electric energy while consuming the metal aluminum.
Since the voltage of the metal-air battery 1 is low in actual operation, in order to ensure the voltage of the metal-air battery device 100, the metal-air battery device 100 is generally composed of a plurality of metal-air batteries 1 connected in parallel or in series. Wherein, the metal-air battery device 100 includes: the plurality of stacked metal-air batteries 1 are stacked, so that the overall volume of the metal-air battery device 100 is smaller, the occupied arrangement space is smaller, and the arrangement is more convenient.
Because traditional metal-air battery can produce a large amount of heats when taking place chemical reaction in inside, lead to metal-air battery device's everywhere temperature distribution inhomogeneous, wherein, the metal electrode in the metal-air battery that is located the higher middle part of heat can consume in advance to lead to metal-air battery device to cut off the power supply in advance under the condition that metal has not yet consumed, make metal-air battery device can't fully release the electric energy. In addition, chemical substances generated by the metal electrode in the discharging process can be enriched on the surface of the metal electrode, so that the reaction area of the metal electrode is reduced, the metal electrode cannot fully react, the voltage of the metal-air battery is reduced, and the output power is reduced.
To this end, the metal-air battery system 1000 according to the embodiment of the present invention has an electrolyte storage tank (not shown in the drawings) capable of storing an electrolyte, and an electrolyte flow channel capable of connecting the electrolyte flow spaces 17 of the metal-air batteries 1 in series is provided in the metal-air battery device 100, the electrolyte storage tank is communicated with the electrolyte flow channel, the electrolyte is circulated between the metal-air batteries 1 and the electrolyte storage tank by a pump or the like, and a temperature control device is provided thereon to ensure that the electrolyte is at a proper temperature and that chemical substances are not concentrated on the metal electrode 13, thereby ensuring smooth operation of the metal-air battery device 100.
In a traditional metal-air battery system, in the process of circulating flow of electrolyte in a metal-air battery device, flow fields in the metal-air batteries are not uniform, so that discharge rates of the metal-air batteries in the metal-air battery device are not uniform, and consumption of metal electrodes in part of the metal-air batteries is high, so that after the metal electrodes of part of the metal-air batteries are consumed, the rest part of the metal-air batteries cannot fully release electric energy, and the non-uniform flow fields in the metal-air batteries can also cause formation of dead zones in the metal-air batteries, so that local consumption of the metal electrodes is too high, the metal electrodes are perforated or even broken, voltage of the metal-air batteries is reduced or discharge is stopped, and the overall discharge duration of the metal-air battery system is influenced.
To this end, the embodiment of the invention designs a metal-air battery system 1000, in which the electrolyte can flow uniformly in the metal-air battery device 100, and the flow field inside the metal-air battery 1 is more uniform. Therefore, the liquid flow of each metal-air battery 1 in the metal-air battery device 100 is ensured to be more uniform, so that the discharge rate of each metal-air battery 1 can be consistent, the flow field in each metal-air battery 1 can be more uniform, so that each part of the metal electrode 13 can be more uniformly consumed, the metal-air battery device 100 can stably release electric energy, and the service life of the metal-air battery device 100 is prolonged.
The electrolyte inlets 15 and the electrolyte outlets 16 of the plurality of metal-air batteries 1 are respectively connected in parallel, and the electrolyte inlets 15 and the electrolyte outlets 16 of the plurality of metal-air batteries 1 are respectively connected in parallel to form an electrolyte inlet flow channel and an electrolyte outlet flow channel together. And sealing soft rubber is respectively injected at the joint between the electrolyte inlet 15 and the electrolyte outlet 16 of the metal-air batteries 1 so as to ensure the sealing performance of the electrolyte inlet flow channel and the electrolyte outlet flow channel.

Therefore, the electrolyte can uniformly flow through the surface of the metal electrode 13, so that the metal electrode 13 can be uniformly consumed, the phenomena of perforation or fracture and the like of the metal electrode 13 are avoided, the utilization rate of the metal electrode 13 is improved, and the discharge time of the metal-air battery system 1000 is prolonged. In addition, since the distance between the stack liquid inlet pipe 500 and the stack liquid outlet pipe 600 and the metal electrode 13 is increased and the flow speed of the electrolyte is reduced by the flow guide assembly 19, the leakage current of the metal-air battery device 100 can be effectively reduced, and the output power of the metal-air battery device 100 can be improved.
