The present invention adopts seven kinds of alloying elements to carry out compatibility, wherein alloying element Mg contributes to carrying heavy alloyed corrosion resistance, alloying element Ga is on the impact of aluminum alloy anode material, be mainly manifested in the anisotropy changing fine aluminium crystal grain and exist in course of dissolution, thus aluminum alloy anode material is corroded evenly.Alloying element Ga and other alloying element, under electrode operating temperature, form eutectic mixture, destroy aluminium surface passivated membrane, activation is produced to aluminum alloy anode material, but Ga content is more than 0.5%, the current potential of aluminum alloy anode material becomes negative, obviously will reduce current efficiency.Bismuth additions can form eutectic mixture with other alloying element, destroys the passivating film on aluminium surface.But the content of Bi is more than 1.0%, this alloying element easily separates out accumulation at grain boundaries, accelerates the corrosion certainly of aluminum alloy anode material.Alloying element Ce adds the intensity improving alloy, and Ce partly can replace the position of Mg element, is solid-solubilized in α-Mg solid solution with the form of subrogating solid solution; Ce can the crystal grain of refining alloy as-cast structure, makes alloy phase that " suspension " occur and reduce its relative scale in the tissue; And serve the effects such as desulfurization, deoxidation, change inclusion morphology, crystal grain thinning and surface modification in the alloy.Alloying element Pb can improve the machinability of alloy material.
The aluminum alloy anode material for battery that the present invention develops, add high hydrogen overpotential alloy element, change electrode surface state, high hydrogen overpotential element is as negative electrode during hydrogen ion discharge, add the polarization of evolving hydrogen reaction, thus inhibit the precipitation of hydrogen, improve aluminum alloy anode utilance.
The aluminum alloy anode material for battery that the present invention develops, due to following three reasons: 1, seven kinds of alloying element compatibilities are reasonable, wherein low-melting alloy element is that solid solution condition disperse is uniformly distributed in Al crystal grain, make Al anode when there is electrochemical reaction, its surface can not generate continuous print passivating film; 2, seven kinds of alloying element compatibilities are reasonable, the alloy element of low melting point dissolves along with the electrochemical reaction of Al anode, impel coming off of Al anodic attack product, new active A l anode surface is constantly reacted with electrolyte, reduce Al anode resistance and polarize and electrochemical polarization; 3, seven kinds of alloying element compatibilities are reasonable, and the low melting point that dissolving comes off, high hydrogen overpotential alloy element are deposited on aluminum alloy anode surface again, thus make aluminum alloy anode be in high activity surface state all the time.

The purity of described aluminium is 99.99%.
Another object of the present invention is the manufacture method providing above-mentioned aluminum alloy anode material for battery, and the method comprises the following steps:
A, moulding by casting: first aluminium ingot is added in graphite crucible and melt with resistance furnace, the metallic element except aluminium of formula ratio is added under melt temperature is 750-900 DEG C of condition, fully stir with graphite rod after all metals melt completely, leave standstill 1-5 minute, pour into slab ingot;
B, Homogenization Treatments: obtain finished product by cold rolling after homogenizing annealing for the slab ingot of above-mentioned moulding by casting.
The present invention is not by means of only reasonable to seven kinds of alloying element compatibilities, and determine melting, processing and heat treated optimised process, thus develop seven yuan of aluminum alloy anode material for battery all under heavy-current discharge condition and under low discharging current condition with good electric chemical property.
In the manufacture method of above-mentioned aluminum alloy anode material for battery, as preferably, steps A also comprises: in the aluminum alloy melt after fusing, add carbon trichloride slagging-off, and pass into argon gas degasification, argon gas gauge pressure is 0.05-0.2MPa, duration of ventilation is 3-5 minute, and further preferably, argon gas gauge pressure is 0.1MPa.
By in various villaumite press-in aluminum alloy melt, itself and aluminum alloy melt are reacted, generates AlCl
3with the escaping gas such as HCl, thus the object that adsorbed hydrogen and oxide inclusion float and reach degasification and remove slag.At present, conventional villaumite has ZnCl
2, MnCl
2, C
2cl
6deng.
Adopt dehydration ZnCl
2the advantage of refining is low price, and refining effect is better.But its weak point is will consume part aluminium in refining process, and produces corrosive gas HCl, can pollute environment.In addition, zinc chloride reacts generation a small amount of Zn after adding aluminum alloy melt can remain in aluminium alloy, therefore does not generally adopt this method to controlling strict alloy containing Zn amount.
The cost ratio zinc chloride of manganese chloride is higher, but the water absorption of manganese chloride is less than zinc chloride, dewaters and preserves all very convenient.In addition, after manganese chloride is pressed into aluminium alloy, gasification and evaporation rate are comparatively slow, thus generate AlCl
3the speed of bubble is slow, and its bubble diameter is less, so refining effect comparatively ZnCl
2good.Meanwhile, it is intensified element that a small amount of Mn that reaction generates to stay in aluminium alloy most aluminium alloy, so the use of manganese chloride purifying method in actual industrial production is also more general.But use MnCl
2refining exists and ZnCl
2identical shortcoming, all can generate HCl corrosive gas.In addition, the Mn that reaction generates remains in aluminium alloy, may have adverse effect to some alloy.
Carbon trichloride joins after in aluminum alloy melt and can react, the AlCl that reaction generates
3and C
2cl
4all be insoluble to aluminum alloy melt, can play refining effect, its refining effect is good.In addition, C
2cl
6nonhygroscopic, do not need to carry out processed, and preserve and use all very convenient.In sum, C is selected
2cl
6carry out refining.
Gaseous state refining agent has inert gas (N
2, Ar etc.) and active gases Cl
2two large classes.Not only aluminum alloy melt is insoluble to but also the not aitiogenic inert gas (N with hydrogen by being blown in aluminum alloy melt
2or Ar etc.), obtain no hydrogen bubble.Because these minute bubbles are in floating-upward process, Al can be adsorbed on the one hand
2o
3deng field trash, also by nitrogen or the pressure differential between argon gas bubbles and aluminium alloy contact interface, the hydrogen be dissolved in aluminium alloy can be sucked in bubble on the other hand.After the bubble floating having adsorbed field trash or hydrogen is excluded to liquid level, the object of degassing and removing the gred can be reached.
Although active gases chlorine is insoluble to aluminum alloy melt, can and aluminium and the hydrogen be dissolved in aluminum alloy melt there is strong chemical reaction, HCl and AlCl being insoluble to aluminum alloy melt of generation
3gas and do not participate in the Cl of reaction
2three can play adsorbed hydrogen and oxide inclusion, so its refining clean-up effect is than using pure gas Ar or N
2much better.Although the effect of logical chlorine refining is better, complete equipment more complicated, and chlorine is toxic, harmful and have corrosiveness to equipment, environment, the present invention uses Ar to carry out refining.
In the manufacture method of above-mentioned aluminum alloy anode material for battery, as preferably, temperature when adding the metallic element except aluminium in steps A is 850 DEG C.
In the manufacture method of above-mentioned aluminum alloy anode material for battery, as preferably, in step B, the temperature of homogenizing annealing is 530-560 DEG C, and temperature retention time is 1-3 hour; Temperature time cold rolling is 180-250 DEG C, aluminium alloy flat bloom is cold-rolled to the thick aluminum alloy anode material of 0.4-0.6mm.
