Problems solved by technology

However, the metal hydroxides produced by ordinary metal-air batteries are directly discharged without collection as the electrolyte is replaced, which wastes a lot of metal. If these metal hydroxides are separated, collected, and recycled To the metal fuel rod / plate production unit, which can achieve zero emissions and reduce the cost of metal fuel rods

Abstract

The invention discloses a household magnesium air battery system including a magnesium air battery pack, an electrolyte regeneration tank and an electrolyte circulation pump. A conical funnel is arranged at the bottom of the magnesium air battery pack, and the bottom of each of anode plates of the magnesium air battery pack is provided with an opening communicated with the conical funnel; the conical funnel is communicated with the upper part of the electrolyte regeneration tank through a pipeline, the middle part of the electrolyte regeneration tank is provided with a filter plate, and the bottom of the electrolyte regeneration tank is communicated with the magnesium air battery pack through the electrolyte circulating pump. The household magnesium air battery system is provided with the electrolyte regeneration tank, so that an electrolyte can be regenerated for utilization, and simultaneously generated hydroxides can also be conveniently recycled, the waste discharge during a battery using process is reduced, and the battery using cost is reduced; and at the same time, electrolyte replacement adopts the pump to convey, and thus the battery maintenance is greatly facilitated.

Description

technical field [0001] The invention relates to a metal-air battery system, in particular to a household magnesium-air battery system. Background technique [0002] In recent years, with the development of society, energy crisis and environmental pollution have become one of the main contradictions of social development. This makes the development of environmentally friendly new energy sources a very urgent topic. Metal-air fuel cells use metals (Li, Mg, Al, Zn, Fe, etc.) as the anode active material and oxygen in the air as the cathode active material. It has the advantages of large capacity, low cost, non-toxic and non-polluting, high specific energy and high specific power, and is called "green energy for the 21st century". [0003] Magnesium-air batteries, as a member of metal-air batteries, have a high open circuit voltage, and magnesium metal has a large electrochemical equivalent (2.2Ah / g), second only to lithium and aluminum, but its density is only 1.7...
