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, exists dendrite form and penetrate in discharge process, when battery is under Daheng banishes electricity condition, and the long-time problems such as high-power output deficiency that steadily keep.Reason or electrode pore that these problems produce are excessive, or 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 is to provide 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, comprises the following steps: ether vinyl active liquid, manganese compound, active carbon, adhesive are put into successively to the container stirring formation mixed liquor that fills water.Formation dry material is dried, dewaters, pulverized to described mixed liquor, and temperature is controlled at 120 DEG C-140 DEG C.Described dry material roll extrusion is formed to sheet material on wire netting.Have the described sheet material of hydrophobic membrane to put into iron block folder brushing and carry out carbonization, constant voltage moulding, temperature is controlled at 320 DEG C-350 DEG C.Iron block folder inwall both sides place mat has glass wool cloth.After electrode is smeared to alkali, dry maturation process, temperature is controlled at 240 DEG C-280 DEG C; Electrode after described maturation process is removed to hydrophobicity, the air-dry finished product of making.
Good effect of the present invention is: adopts this manufacture craft can effectively solve the electric 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
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The manufacture method of the porous air diffusion electrode that as shown in Figure 1, one embodiment of the invention provides comprises the following steps:
Step S1, in 2 liters of beakers, add the water of 1300ML.
Step S2, then in this beaker, add 176 grams of 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, high-speed stirred 10-15 minute form mixed liquor.
Step S4, weigh out 100 grams of active carbons in the balance and put into mixed liquor high-speed stirred, after solution is emulsus, proceed in low rate mixing machine.
Step S5,72-84 gram of adhesive added to stirring at low speed 25-30 minute in this milky solution, proceed in drying baker after drying, dewater, pulverizing and form dry material, drying baker temperature is controlled at 120 DEG C-140 DEG C.
Step S6, dry material roll extrusion is formed to sheet material on wire netting.
Step S7, clamp brushing with the iron block of inwall both sides place mat glass wool cloth and have the sheet material of hydrophobic membrane, put in the lump drying baker and carry out carbonization treatment.Temperature is controlled at 320 DEG C-350 DEG C.
Step S8, proceed to constant voltage 3-5 minute in the forcing press of 45T-63T, 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 DEG C-280 DEG C.
It is air-dry that electrode after step S10, 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), painting alkali electrode (Fig. 6) and slaking electrode, and can effectively solve porous air diffusion electrode electric discharge and penetrate and the formation of dendrite, and can be under battery Daheng banishes electricity condition, the high-power output of long-time steadily maintenance.
