Description
Technical Field

Background
The problems of insufficient energy supply, excessive exploitation, environmental pollution caused by using fossil fuel and the like have adverse effects on the current development of human beings. The development of a novel green energy source with high performance and no pollution is urgent. The magnesium/air fuel cell with magnesium and the magnesium alloy as anode materials has the advantages of low cost, cleanness, safety, high theoretical voltage and energy density and the like, is used as a potential green clean energy source, and has wide application prospect in various fields such as movable electronic equipment, marine underwater instruments, autonomous underwater vehicle power supplies, standby power supplies and the like.
However, the magnesium salt which is difficult to be peeled off and a corrosion product passivation film are easy to deposit on the surface of a magnesium electrode in the working process of a magnesium/air battery under the influence of the intrinsic performance (low electrode potential and high chemical activity) of the magnesium alloy, so that the activity dissolution of a magnesium anode is influenced, the discharge area is reduced, the continuous reduction of discharge current (voltage) is caused, and meanwhile, the discharge product is repeatedly adsorbed on the surface of the anode due to turbidity of electrolyte in the reaction process of the battery. These factors make it difficult for the battery to maintain operation at a stable operating voltage and power density.
The prior art mainly adds some alloy elements into magnesium matrix by alloying, and the new phase structure formed after the addition of the elements accelerates the peeling of discharge products from the surface of the magnesium electrode, thereby maintaining the stronger discharge activity of the electrode and obtaining stable discharge voltage and power density. But in view of cost and process, the method is difficult to be applied in large scale and particularly popularized in low-end civil industrial products.

In the method for constructing the magnesium battery, electrolyte is circulated by a water pump and liquid flows wash the electrode plates from top to bottom to obtain the battery with good discharge performance, but the method has some problems. If the power source of the water pump comes from external power, the water pump cannot be suitable for long-time outdoor work, the surface of the magnesium plate is simply flushed from top to bottom by virtue of the gravity of liquid flow, and the covering on the surface of the magnesium plate is difficult to clean thoroughly.
