Abstract
The utility model zinc-air cell with a collector fluit with foaming nickel, comprising an anode, a cathode and a barrier diaphragm, wherein, the anode is provided with a water-proof conductive ventilating cylinder 5; the inner surface of the ventilating cylinder 5 is provided with a catalyst layer 6; the inner side of a foaming nickel cylinder 4 with a micropore is appressed with the outer surface of the ventilating cylinder 5; the outer side of the foaming nickel cylinder is connected with the inner side of a battery case 3 to form an electric passage; the foaming nickel micropore causes air to contact the entire surface of an anode, and simultaneously forms the channel of air convection.
Description
The utility model is relevant with zinc-air battery, especially has the zinc-air battery of porous collector relevant with positive pole.
The contact area of existing zinc-air battery collector is little, adopts spring leaf that air electrode and battery case electricity are connected, and micropore is in anodal surface distributed inequality, and it is inhomogeneous that air enters electrode, little with the contact area of battery case, and the electric pathway of formation is less.
The purpose of this utility model provides a kind of simple in structure, and is easy to manufacture, and discharge performance is good, and polarization performance is good, zinc-air battery with low cost.
The utility model is achieved in that
The utility model has the zinc-air battery of nickel foam collector, comprises positive pole, negative pole and barrier film.Positive pole has waterproof conduction ventilation tube 5, and the inner surface of ventilation tube 5 has Catalytic Layer 6, the outer surface of the inboard fitted and breathable tube 5 of the nickel foam tube 4 of band micropore, and the outside and battery case 3 inboards are connected to form electric pathway,
Around the positive terminal 1 of the utility model shell 3 air admission hole 2 is arranged, ventilation tube 5 has an end opening, the sealing of one end, openend has outward flange dish 14, has on the ring flange 14 discharge orifice 12, and porose 15 with corresponding to discharge orifice 12 on the seal cover 13 of shell 3 and ventilation tube 5 openends, air admission hole 2, nickel foam tube 4, to discharge orifice 12, hole 15 forms air convection channel.
The utlity model has following characteristics:
1, air electrode has adopted new construction, waterproof conduction ventilated membrane, change into and adopt the moulding of thermoplastic pressing one-time, catalytic membrane is to adopt the high activated state cellular material technology of brushing, abandoned traditional made membrane and highly difficult formation method such as the powerful static pressure of multilayer film again, the structural design of this similar garden tubular (garden tube with garden arc cap disjunctor) mutually is more in mechanization production, the battery assembling has also been simplified, and has improved production efficiency widely.
2, on the outer wall of waterproof and breathable conduction garden tube openend, be provided with a circle outer lug boss, and dig several cross-ventilations hole thereon, simultaneously, the outward flange of sealing ring (constituting one) with negative pole end, several holes are also arranged correspondingly, thereby form air convection channel, improved the discharge performance of battery with air admission hole etc.
3, after the existing alkalescence of employing (zinc-manganese) battery overall dimension, just can adopt parts, raw material and the part tooling device of alkaline battery, improve the reliability of technology, reduce production cost again.
4, metal pool band is the nickel foam thin slice that adopts, and porous and conducting electricity is coated on the tube of waterproof and breathable conduction garden, and both having guaranteed the connection of air electrode and battery case electricity provides air duct again.
5, adopt the encapsulation technology of alkaline battery, and use own special sealing glue, anti-effectively leak-stopping alkali phenomenon, good sealing effect.
Following is accompanying drawing of the present utility model:
Fig. 1 is a structure chart of the present utility model
Fig. 2 is a nickel foam tube front view
Fig. 3 is the A-A cutaway view of Fig. 2.
Following is embodiment of the present utility model:
Air electrode is with 4 to constitute by waterproof and breathable conduction garden tube 5, Catalytic Layer 6 and metal pool.Waterproof and breathable conduction garden tube is the matrix of air electrode, is formed by the thermoplastic compacting, and an end opens wide, and the other end is that a garden arc cap constitutes blind end.Catalytic Layer be with by the brushing of catalytic oxidation-reduction thing at waterproof garden tube inwall, form thin film.Metal pool band is the foam nickel strap of porous, carries out the outside (shell portion) that is placed on waterproof and breathable conduction garden tube, in the battery case 3 of packing into, with the path of its formation electricity.Battery case 3 becomes plus plate current-collecting body, by positive terminal 1 outside transmission of electric energy.The distant mistake of outside air is distributed in the air admission hole 2 around the positive terminal 1, and through air diffusion membrane 11, metal is moored with 4 airspaces that provide, and the through whole surface of air electrode enters the electrochemical reaction zone, finishes electrochemical reaction, obtains electric energy.Be added with a circle outer lug boss in the outside of the openend of waterproof garden tube 5, and on this, dig several cross-ventilations hole.Cylindrical diaphragm 7 is packed in the tube of air electrode garden, is close to inwall, filling pasty state zinc electrodes 8 in the cylindrical diaphragm 7.Negative pole end 10 has sealing ring (there are several breach at its edge, and is corresponding with the cross-ventilation aperture), and is welded with a negative pole palpus 9, can insert in the calamine cream from the air electrode opening end, becomes negative current collector, and sealing ring scribbles rubberizing, finishes cell sealing.
The waterproof and breathable conduction garden tube materials of air electrode are acetylene black, fluoroplastics, additive etc., and concrete the making is that acetylene black (13-26%), fluoroplastics (67-60%) and additive (20-14%) etc. are constantly stirred, and fully mixes.Pull the condensation product oven dry out, be crushed to (50-100 order) powder, fill in the garden tubular that is hot pressed into an end band garden arc cap in the mould.Catalytic Layer is with the evenly mixing of Mn oxide (55%~10%) of active carbon (45-90%) and chemical preparation, is modulated in the colloidal fluid again, and through stirring into rare shape liquid, brushing is used after drying, the extracting on the tube inwall of garden.The metal pool is with the thin slice that is rolled into 0.1-0.2mm with the foam nickel strap again, cuts out in flakes by dimensional requirement, is covered on the drum outer wall of garden, in the battery case of packing into.Reinstall cylindrical diaphragm, inject the pasty state calamine cream thereafter.Calamine cream is formed by alkaline electrolyte solution (22.5-28.5%) modulation of metal zinc (66~66.5%), corrosion inhibiter (9~4%), bonding agent (7~1.5%), water absorbing agent (1.5~0.5%) and band zinc oxide.Be welded with negative pole on the negative pole end and must and have sealing ring, insert calamine cream, the air electrode opening end is sealed up (breach on the sealing ring limit aligns with the cross-ventilation hole).
