Description
Technical field
The present invention relates to air cell field, particularly relating to a kind of take manganese-containing aluminum alloy as the air cell of anode material and the preparation method of anode material.
Background technology
Metal-air cell is new generation of green storage battery, and its low cost of manufacture, nontoxic, specific energy is high, raw material recoverable, superior performance.The more metal-air cell of current research has zinc-air cell, aluminum-air cell and lithium-air battery etc., only has zinc-air cell with industrialization is immediate.Due in galvanic series, aluminum ratio zinc is more active, and can obtain higher cell voltage, and an aluminium atom can release three electronics, and a zinc atom discharges two electronics, aluminium can improve the energy of battery.In addition, aluminium is can mass-produced cheap metal, therefore the research of aluminum-air cell, and open a wide prospect, its progress is very rapid, is a kind of rising air cell.
Aluminium has the advantage of its uniqueness as the anode material of air cell: (1) electrochemical equivalent is high, and the electrochemical equivalent of aluminium is 2980Ah/kg, is metal the highest except lithium; (2) electrode potential is more negative, in neutral solution, its standard electrode potential is-1.66V(vs.SHE), in alkaline solution, its standard electrode potential is-2.35V(vs.SHE), antianode material, current potential is more negative better, and battery can provide larger electromotive force; (3) aboundresources of aluminium, cheap.
At present, air cell aluminium anodes material is compared with zinc anode material, and the matter of utmost importance of existence is exactly have very strong affinity between aluminium and oxygen, thus fine aluminium very easily passivation in aqueous, surface coverage one deck stablizes fine and close Al
2o
3oxide-film, makes the current potential of fine aluminium in neutral solution be only-0.8V(vs.SHE), do not reach its theoretic electrode potential, the requirement of anode material to voltage can not be met; Another serious problems that aluminum-air cell anode material exists are, aluminium is very serious from corrosion liberation of hydrogen in neutral solution particularly alkaline solution, causes anode utilance greatly to reduce, and has voltage delay phenomenon during electric discharge.Above two problems hinders the commercial applications of aluminum-air cell.In order to eliminate the oxide-film on aluminium surface, usually adopting alloying process, adding some alloying element and aluminium is activated, effectively stop or suppress aluminium surface to form oxide-film fine and close continuously; In order to reduce aluminium from corrosion rate, generally all adopt the higher aluminium of purity (>=99.9%) and add some alloying element with high overpotential of hydrogen evolution and alloying is carried out to aluminium.
Study verified, add one or more a small amount of alloying elements in aluminium, significantly can improve the chemical property of aluminium alloy, destroying its oxide-film increases that it is active, thus makes that fine aluminium current potential is negative to be moved.The alloy element that aluminum-air cell anode material is conventional mainly contains zinc, magnesium, sows, indium, tin, lead, mercury, bismuth etc.These elements add in aluminium and form the multicomponent alloy such as ternary, quaternary.Better performances have the electrochemical behavior of Al-In-Mg(Al-In-Mg line aluminium alloy anode in NaOH solution, light-alloy process technology, 2004,10:39-42), Al-Ga-Mg(Al-Ga-Mg alloy structure and anode performance study, Chinese corrosion and protection journal, 2005,6:336-339), the electrochemical behavior of Al-Ga-Bi-Pb(Al-Ga-Bi-Pb alloy in alkaline electrolyte, power technology, 2009,5:368-370) etc. be alloy.The purity of the raw material aluminium that current aluminum-air cell uses is all more than 99.9%, and this is mainly in order to reduce the corrosion certainly of the aluminium anodes material that impurity elements of ferrum causes, but rafifinal is expensive.
Summary of the invention
The object of the present invention is to provide a kind of manganese-containing aluminum alloy anode material.
In addition, the present invention also aims to the preparation method that a kind of anode material is provided.
The present invention also aims to provide a kind of from corrosion rate low take manganese-containing aluminum alloy as the air cell of anode material.
In order to solve the problems of the technologies described above, the present invention is realized by following scheme: with the aluminium of purity >=99.7% (Al) for primary raw material, Addition ofelements magnesium (Mg), tin (Sn), sow (Ga) and manganese (Mn), the mass percent of institute's Addition ofelements is: Mg:0.05 ~ 2.5%; Sn:0.05 ~ 1.5%; Ga:0.05 ~ 2.5%; Mn:0.1 ~ 1%.
Adopt the air cell manganese-containing aluminum alloy anode material of technique scheme; by purity be>=99.7% aluminium based on; add Mg, Sn, Ga and Mn element of trace; object destroys the alumina protective layer of its densification; improve its chemical property and surface dissolution uniformity; and reduce it from corrosion rate, particularly in aluminium alloy, add trace manganese, manganese and iron preferentially can be combined the second-phase Al formed containing manganese and iron
6(Fe, Mn), this phase current potential is close with base aluminum current potential, can slow down the corrosion certainly of aluminium alloy, thus improve anode utilance.
The preparation method of anode material is: (1) is under inert gas shielding, aluminium ingot all melts when being 680 ~ 700 DEG C by temperature in elevated temperature vessel, then add magnesium ingot, aluminium manganese intermediate alloy, tin grain and sow grain, limit heating edge rotary container, motlten metal is mixed, continue to be heated to 750 ~ 770 DEG C, after insulation 5 ~ 7min, pour into block slab ingot; (2) by the slab ingot of cast molding in 400 ~ 550 DEG C of homogenizing annealing 4-10h, make alloying element at high temperature spread evenly; (3) slab ingot after annealing is rolling to the thick manganese-containing aluminum alloy anode material of 0.5 ~ 4mm at 150 ~ 200 DEG C.Can obtain open circuit voltage negative (-1.6 ~-1.8V (vs.SHE)), anode utilance high (>=94%), from the low (≤0.03mg/cm of corrosion rate
2h), cell is 100 ~ 300mA/cm at discharge current density
2the electromotive force of scope build-in test 120h is 1.5V ~ 1.8V, surface corrosion uniform high-performance air cell manganese-containing aluminum alloy anode material.
The material adopting such scheme to prepare is the anode of air cell, and the negative electrode of this air cell is made up of Catalytic Layer, nickel screen conducting matrix grain and waterproof ventilative layer, and wherein Catalytic Layer is γ-MnO
2, active carbon and polytetrafluoroethylene be by weight (0.5 ~ 2): (2 ~ 4): (1 ~ 3) mixes roll extrusion and makes the thick film of 0.3 ~ 0.5mm, watertight composition is that polytetrafluoroethylene and acetylene black are made the thick film of 0.3 ~ 0.5mm by weight 1:1 mixing roll extrusion, finally Catalytic Layer, nickel screen and waterproof ventilative layer is pressed into the thick air cathode of 0.3 ~ 0.5mm.Electrolyte is 1 ~ 4MNaCl.
The present invention considers from alloying aspect to improve the chemical property of aluminium anodes material and to reduce it from corrosivity: aluminium alloy, add appropriate magnesium, tin and sow, particularly adding manganese element.Impurity elements of ferrum in aluminium alloy is dissolved in aluminum substrate hardly, but with large block Fe
3the form of Al second-phase is present in aluminum substrate, and this phase current potential calibration, forms microcorrosion galvanic couple with base aluminum, and cause aluminium anodes to cause anode utilance extremely low from corrosion, it is uneven that large block iron also causes alloy surface to dissolve mutually.In aluminium alloy, add trace manganese, be because manganese and iron preferentially can be combined the second-phase Al formed containing manganese and iron
6(Fe, Mn), this phase current potential is close with base aluminum current potential, can slow down the corrosion certainly of aluminium alloy, thus improve anode utilance; Adding trace magnesium can refining aluminum alloy crystal grain, and magnesium can form Mg in the alloy
