Description

A kind of magnesium metal-air battery

Technical field

The utility model relates to a kind of chemical cells for converting chemical energy to electric energy, and in particular to a kind of magnesium metal-air Battery.

Background technique

It is cathode that magnesium metal-air battery, which is with magnesium or its alloy material, is anode with the oxygen in air, general universal Use saline solution, seawater or light water for a kind of chemical cell for converting chemical energy to electric energy of electrolyte aqueous solution, magnesium gold Belong to or its alloy is in the case where porous activated carbon largely adsorbs the effect of the oxygen catalytic in air, occurs with the water in electrolyte aqueous solution Redox reaction, magnesium metal or its alloy oxidation local behavior hydroxide continue externally to export electric energy.

Magnesium metal abundant raw materials, can store for a long time in air, price is relatively cheap, energy density is high, it is safe and reliable, The series of advantages such as environmental protection, reaction product recycling, are a kind of new green energies.Have in daily life and army wide General application prospect, such as daily emergency lighting, rescue and relief work, field exploration, seawater utilization exploitation, mobile communication field can produce Raw good economic benefits.

At present in the magnesium metal-air battery of this field, especially disposable magnesium metal-air battery, structure and manufacture It is relative complex in technique, expensive, especially the material of air cathode using upper.

Summary of the invention

The goal of the invention of the utility model is: overcoming the above-mentioned deficiency of the prior art, the utility model provides a kind of magnesium Metal-air battery.

The technical solution adopted in the utility model is: a kind of magnesium metal-air battery, including by positive electrode collector layer, air The basic battery unit of anode layer, magnesium metal negative electrode layer composition, uses insulator separation, adopts when multiple basic battery units stack The connection that multiple basic battery cells in series stack, the basic battery list of sheet are realized with conducting wire connection, thin nickel sheet electric resistance welding mode Both ends are connected by symmetrical pull rod and are axially flexibly clamped and fixed along pull rod using pressing plate when member series connection stacks, and can be grown before being not used Phase storage, when power generation, make air cathode layer suck electrolyte aqueous solution, and the electrolyte aqueous solution is saline solution, seawater or general Water flowing, it is characterized in that: at least one basic battery unit, the basic battery unit has on the surface of magnesium metal negative electrode layer On successively close lamination have air anode layer, positive electrode collector layer.

The air cathode layer at least part is connected to outside air, and material is the porous work of finished product blanket hydrophilic electroconductive Property charcoal.

The positive electrode collector layer is more corrosion resistant graphite, carbon, stainless steel, copper (including copper-clad plate) conductive material It is any.

The magnesium metal negative electrode layer includes magnesium alloy materials.

The magnesium metal negative electrode layer shape is light sheet, bar, wire rod, tubing any one.

The beneficial effects of the present invention are: the structure of battery is simple, light and handy, it, can be straight outside demagging metal or its alloy anode layer It connects and uses more cheap finished-product material, and eliminate what especially disposable magnesium metal-air battery in the prior art was typically provided with Membrane layer, internal resistance of cell relative reduction, simplifies structure, reduces costs.
