Description
Technical field
The invention belongs to electrochemical technology field, more particularly to one kind with magnesium metal or magnesium alloy as anode,
The carrier of liberation of hydrogen catalyst is supported with for negative electrode, water is the magnesium water battery of cathode reactant.
Background technology
Construction ocean power is this century China's proposition for ocean development and the target for utilizing.In this background
Under, towards deep-sea, the exploration of off-lying sea and the study hotspot for being developed into marine field.Therefore, on can meeting
Stating the marine settings that environment uses becomes particularly important, in the urgent need to the operating depth for increasing equipment simultaneously extends work
Make the time.Power supply be determine marine settings can normal work important component.Due to the actual work in ocean
Under the limitation of condition, particularly deep sea condition, conventional one-shot battery (alkaline Mn cell, lithium primary battery) and
Secondary cell (such as lead-acid battery, smee cell, lithium ion battery) is difficult to meet underwater equipment pair
Large Copacity, long-life, the demand of safe and reliable and good marine environment adaptability power supply.
Magnesium sea water battery is the battery system that a class can be used in the seawater.Such battery is closed with magnesium metal or magnesium
Gold is oxidant for anode, oxygen, Dissolved Oxygen in Seawater, hydrogen peroxide etc., directly uses sea water as electricity
Xie Zhi.Wherein, magnesium dissolved oxygen seawater battery is a kind of typical Magnesium sea water battery, and the advantage of the battery includes：
First, energy density is high.Because the cathode oxidant and electrolyte except magnesium anode dispatch from foreign news agency pond are all from seawater, because
This battery actual mass specific energy is up to hundreds of every kilogram of watt-hours；2nd, raw material sources enrich.China's magnesium reserves
It is abundant and cheap；3rd, storge quality is good.Battery is in not state of activation, storage when not contacting seawater
Deposit for up to the several years.However, because magnesium dissolved oxygen seawater battery performance is influenceed by Dissolved Oxygen in Seawater concentration
Larger, the actually used of the battery is restricted, with certain limitation.Dissolved Oxygen in Seawater it is dense
Degree is influenceed by sea water advanced, temperature, waters.Wherein, it is sea water advanced that maximum is influenceed on it.Seawater is molten
Solution oxygen concentration reaches minimum with the continuous reduction of the depth of water at nearly 1000 meters.When the reduction of seawater dissolved oxygen concentration
When, battery performance declines rapidly, it is difficult to meet the normal power demands of marine settings.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes one kind with magnesium metal or magnesium alloy as anode, load
The porous material for carrying liberation of hydrogen catalyst is negative electrode, the magnesium water battery with water as cathodic fuel.The battery electrode and
Cell reaction equation is as follows：
Anode reaction：Mg+2OH-→Mg(OH)2+2e-
Cathode reaction：2H2O+2e-→H2+2OH-
Cell reaction：Mg+2H2O→Mg(OH)2+H2
The present invention adopts the following technical scheme that to realize：
A kind of magnesium water battery, including magnesium or magnesium alloy anode, barrier film, it is loaded with liberation of hydrogen catalyst cathode and negative electrode
Reactants water；The anode is oppositely arranged with the negative electrode, and the barrier film is arranged at therebetween, the sun
Pole, negative electrode, barrier film are placed in water.
The magnesium water battery is Open architecture, and now water flows between anode and the negative electrode.
The magnesium water battery is enclosed construction, and now water is stored between anode and the negative electrode.
The active ingredient of the liberation of hydrogen catalyst is transient metal sulfide, transition metal phosphide, transition metal
One or more in phosphide, transition metal, the alloy of more than two kinds transition metal.
The liberation of hydrogen catalyst carrier that is loaded with is the one kind in nickel foam, nickel screen, carbon fiber felt, active ingredient in
Quality loading 5%-40% on catalyst.
The barrier film is Polymer non-woven porous film material, and membrane pore size is less than or equal to 0.1um.
The barrier film is in polyethylene film, polypropylene screen, polyvinyl alcohol film, Nafion membrane, hydrophilic PTFE film
One kind.
The magnesium alloy is magnesium and one or more alloy in tin, indium, zinc, mercury.
Pile is connected and composed by way of serial or parallel connection or serial-parallel mirror between the 2 section above magnesium water battery,
Electric energy needed for providing.
Beneficial effects of the present invention：
Compared with prior art, the present invention has simple structure, easy to use, when using it for seawater under water
The advantages of not limited by Dissolved Oxygen in Seawater concentration.
The magnesium water battery being applied under water of the present invention, first, the battery with seawater as cathode reactant,
Dependence of traditional magnesium dissolved oxygen seawater battery to oxygen concentration in seawater is solved, even if the battery under oxygen-free environment
Also can normal work, drastically increase the stability of battery；Secondly, only needed between the power cell anode-cathode
Barrier film separates and leaves the passage of hydrogen exclusion, need to be left with traditional magnesium dissolved oxygen seawater battery larger
Open space ensure that the continuous renewal of fresh seawater is compared, magnesium water battery structure is compact, small volume, battery
Energy density per unit volume is obviously improved；Furthermore, the battery ensures seawater normal work by, therefore can pass through
Flow channel length and sectional area between monocell is controlled to reduce short circuit current, so as to realize the serial chain between battery
Connect, it is to avoid magnesium dissolved oxygen seawater battery can only single-unit use and need boosting inverter to improve output voltage and make
Into the problem of energy loss.
