Abstract
The utility model relates to a zinc-air battery with an air permeable film, comprising a positive electrode, a negative electrode and a diaphragm. The periphery of the positive electrode end of a battery case 3 is provided with an air inlet 2; the positive electrode of the battery is provided with a water-proof ventilating and conducting cylinder 5 of which one end is closed; the other end of the conducting cylinder 5 is opened; a micro hole is arranged on a cylinder wall; the inner wall of the conducting cylinder 5 is provided with a catalyzing film 6; the outer wall of the conducting cylinder is appressed with a multi-hole current collector 4; at least one air diffusion film 11 and one dispersing film are connected with the current collector 4 and are contacted with the case 3 between the air inlet 2 of the battery case and the closed end of the conducting cylinder, and thus air entering an air electrode is uniformly distributed, improving the polarizing property of the battery.
Description
The utility model is relevant with zinc-air battery.
Have air admission hole to communicate with air electrode around the positive terminal of existing zinc-air battery, owing to the area of the collector on the air electrode surface area greater than air admission hole, it is inhomogeneous that air enters electrode, the battery polarization poor performance, and the heavy-current discharge characteristic is poor.
The purpose of this utility model provides the good zinc-air battery of a kind of battery polarization performance.
The utility model is achieved in that
The utility model has the zinc-air battery of air ventilated membrane, comprises positive pole, negative pole and barrier film.Around the positive terminal 1 of battery case 3 air admission hole 2 is arranged, anode has waterproof and breathable conductive tube 5.The sealing of conductive tube 5 one ends, an end opening has micropore on the barrel, the conductive tube inwall has catalytic membrane 6, outer wall is close to porous collector 4, has at least one deck air diffusion membrane 11 to link to each other with porous collector 4 with dispersion membrane 16 between battery case air admission hole 2 and the conductive tube blind end, contacts with shell 3.
The utility model porous collector 4 is the nickel foam tube, and the outer surface of conductive tube 5 is close in the inboard of tube, and the outside of tube is connected with the inboard of shell 3.
The utility model air diffusion membrane 11 and dispersion membrane respectively are layer 2-4, and the openend of conductive tube 5 has outward flange dish 14, have cross-ventilation hole 12 corresponding with the hole 15 on the seal cover 13 on the ring flange 14, air admission hole 2, diffusion barrier 11, porous collective 4 forms air convection channel to discharge orifice 12 and hole 15.
The utility model diffusion barrier 11 and dispersion membrane 16 are garden annular polypropylene film sheet, are enclosed within proper order by dispersion membrane, diffusion barrier on the garden arc cap closure end of conductive tube 5, and the edge contacts with shell 3.
The utility model is one or more layers ventilated membrane of equipment under air admission hole, and the air ventilated membrane is divided into diffusion barrier 11 and dispersion membrane 16, and they all are polypropylene screens, be shaped as the garden annular, press diffusion barrier, dispersion membrane order lamination, be enclosed within on the garden arc cap of waterproof cylindrical shell, be in the air admission hole below.Insert the air that enters from air admission hole 2 in the battery case, enter the air chamber that interlayer forms through diffusion barrier 11 earlier, through dispersion membrane 16 even air is distributed again.The aperture of diffusion barrier 11 is bigger than dispersion membrane, and the film of small-bore makes and directly goes into air and be obstructed and disperse, and enters air electrode with making quantitative and even, thereby has improved the battery polarization characteristic, has improved the heavy-current discharge characteristic.Simple in structure, easy to manufacture, with low cost.
Following is accompanying drawing of the present utility model:
Fig. 1 is a structure chart of the present utility model
Fig. 2 is an air ventilated membrane structure chart.
Following is embodiment of the present utility model:
Air electrode is made of waterproof and breathable conduction garden tube 5, Catalytic Layer 6 and nickel foam tube 4.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.The foam nickel strap of porous is carried 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.Outside air is by being distributed in the air admission hole 2 around the positive terminal 1, through air dispersion film 16, and diffusion barrier 11, the airspace that nickel foam tube 4 provides, 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.
