Abstract
The invention provides a method for manufacturing porous air diffusion electrode. The method includes sequentially adding ether-ethylene type active liquid, manganese compound, activated carbon and binder into a container filled with water, stirring to obtain mixed solution, drying, removing water and pulverizing into dried powder at 120-140 DEG C; rolling the dried powder into sheet material; placing the sheet material coated with a hydrophobic film into an iron clip, carbonizing, forming under a constant pressure at 320-350 DEG C; wiping alkali on the electrode, drying and aging at 240-280 DEG C; and removing the hydrophobic film. The two sides of the inner walls of the iron clip are lined with glass fiber cloth. The invention can prevent discharge strike and formation of crystals on the electrode, and ensures long-period stable high power output under the conditions of constant current discharge.
Description
Technical field
The present invention relates to a kind of manufacturing process of chemical power source, particularly a kind of manufacture method of porous air diffusion electrode.
Background technology
The energy resource supply of Present Global is increasingly deficient, and people are exploring the new energy.Common zinc-air cell exists cycle life affects competitiveness, in discharge process, exist dendrite to form and penetrate, when battery under Daheng banishes electricity condition, the long-time problem such as high-power output deficiency that steadily keeps.Reason or electrode pore that these problems produce are excessive, or the diffusion electrode material component participates in exoelectrical reaction, or diffusion electrode density is solidified not or manufacturing process does not cause comprehensively.
Summary of the invention
Technical problem to be solved by this invention provides a kind of manufacture method of porous air diffusion electrode.
For solving the problems of the technologies described above, the present invention realizes as follows: a kind of manufacture method of porous air diffusion electrode may further comprise the steps: ether vinyl active liquid, manganese compound, active carbon, adhesive are put into the container that fills water successively stir the formation mixed liquor.The formation dry material is dried, dewaters, pulverized to described mixed liquor, and temperature is controlled at 120 ℃-140 ℃.Described dry material roll extrusion is formed sheet material at wire netting.Have the described sheet material of hydrophobic membrane to put into the iron block folder brushing and carry out carbonization, constant voltage moulding, temperature is controlled at 320 ℃-350 ℃.Iron block folder inwall both sides place mat has glass wool cloth.Dry maturation process after electrode smeared alkali, temperature is controlled at 240 ℃-280 ℃; Electrode after the described maturation process is removed hydrophobicity, the air-dry finished product of making.
Good effect of the present invention is: adopts this manufacture craft can effectively solve the discharge of porous air diffusion electrode and penetrates and extremely brilliant formation, and can be under battery Daheng banishes electricity condition, the long-time steady high-power output that keeps.

Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the manufacture method of the porous air diffusion electrode that provides of one embodiment of the invention may further comprise the steps:
Step S1, in 2 liters of beakers, add the water of 1300ML.
Step S2, then in this beaker, add 176 gram ether vinyl active liquids, with homogenizer high-speed stirred number minute.
Step S3, after solution fully mixes, in this beaker, add the manganese compound of 15-25 gram, formed mixed liquor in high-speed stirred 10-15 minute.
Step S4, weigh in the balance out 100 the gram active carbons put into the mixed liquor high-speed stirred, after solution is emulsus, change in the low rate mixing machine.
Step S5,72-84 is restrained adhesive added in this milky solution stirring at low speed 25-30 minute, change in the drying baker and form dry material after drying, dewater, pulverizing, the drying baker temperature is controlled at 120 ℃-140 ℃.
Step S6, the dry material roll extrusion is formed sheet material at wire netting.
Step S7, clamp the sheet material that brushing has hydrophobic membrane with the iron block of inwall both sides place mat glass wool cloth, put in the lump drying baker and carry out carbonization treatment.Temperature is controlled at 320 ℃-350 ℃.
Step S8, change in the forcing press of 45T-63T constant voltage 3-5 minute over to, pressure remains on 32kg/cm
2-45kg/cm
2, take out electrode and smear alkali.
Step S9, this electrode is put into the maturation process that drying baker carries out 45-120 minute, temperature is controlled at 240 ℃-280 ℃.
It is air-dry that electrode after step S10, the taking-up maturation process is removed hydrophobicity, forms finished product.
Adopt this manufacture craft can prepare the porous air diffusion electrode of three kinds of different size technical data: neutral electrode (seeing Fig. 5), to be coated with alkali electrode (Fig. 6) and slaking electrode, and can effectively solve porous air diffusion electrode discharge and penetrate formation with dendrite, and can be under battery Daheng banishes electricity condition, the high-power output of long-time steadily maintenance.
