Description
Technical field:
The device that it is electric energy that the utility model relates to a kind of direct transformation chemical energy, particularly flat metal-air cell.
Background technology
The at present actual chemical cell kind of using is more various, the battery of property use once, but the repeated charge battery is also arranged.These batteries have a common feature, and exactly that the both positive and negative polarity chemical reaction is required active material is stored in inside battery, and the active material that the energy of battery output all relies on inside battery to store provides, and this just makes battery output energy be restricted.
In recent years, the research of metal-air cell is comparatively active, metal-air cell and above-mentioned battery relatively, it is big, cheap to have an output energy, can utilize in the air oxygen as the active material of positive pole.Save characteristics such as earth resource.At present in the metal-air cell field, the design of patent or product structure all is to be the form on vertical base and deisgn product structure with the negative pole.With reference to Fig. 1, existing air cell generally includes air electrode 1, negative pole 2, barrier film 3 and electrolyte 5.Air electrode 1 is arranged in parallel with negative pole 2 vertical bases, and electrolyte 3 is filled in the space between air electrode and the negative pole.This structure of air cell exists in actual use builds under the negative pole or fracture, make the active material of negative pole 2 be deposited in the bottom of air cell, cause the air cell output capacity to reduce, output current density reduces, air electrode 1 bottom pressurized, the problems such as useful life of shortening air electrode.
Invention constitutes
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provides a kind of metal-air cell negative pole that can solve fully the flat metal-air cell structure of base, fracture down in use to occur.The battery of this structure can guarantee that in the process of vibration, transportation, long preservation the negative pole shape that holds its shape is constant, makes battery regular picture performance, and especially the dynamic discharge performance has had sufficient assurance.
The purpose of this utility model can realize by following approach:
Flat metal-air cell comprises air electrode, negative pole, electrolyte, barrier film, housing, negative pole expansion cushion chamber, steam vent or explosionproof hole.Its main points are that the metal-air cell structure is flat shape, and the size of length or Width is greater than the size of short transverse, and air electrode is the upper base of air cell and goes to the bottom, perhaps is upper base, perhaps for going to the bottom.Negative pole is parallel to upper base or goes to the bottom at inside battery, or has certain included angle with air electrode.Like this, because negative pole is horizontal positioned basically, pass through barrier film, electrolyte closely contacts with air electrode, with regard to the problem of having avoided negative pole in transportation, use, to be out of shape owing to vibrations, negative pole is remained unchanged substantially with respect to the shape of air electrode, and making negative pole reach design capacity has had reliable basis.Because the negative pole dimensionally stable, but negative pole is with regard to stable output current.
The utility model can also further be specially:
There are multiple choices the position of air electrode in air cell, below is wherein four kinds.
Air electrode is going to the bottom of air cell, and air electrode comprises watertight composition, air-permeable layer, collector, Catalytic Layer.Upper base and side are the housing of air cell, and housing is processed by macromolecule polymer material, also can be by metal material processing.Negative pole can parallel placement with air electrode, also can have certain included angle.Negative pole closely contacts with air electrode by electrolyte or barrier film, and the parallel air electrode top that is assemblied in of negative pole just can effectively solve under the negative pole and build, is out of shape, the problem that the output energy reduces.Reserve certain space between negative pole or electrolyte and the upper base, use, steam vent or explosionproof hole are installed in a certain position of upper base or side as negative pole expansion cushion chamber.
Air electrode is the upper base of air cell, goes to the bottom to constitute the housing of air cell with the side, and housing is processed by macromolecule polymer material.Side or upper base at housing have a salient position, as negative pole expansion cushion chamber, at the top of cushion chamber steam vent or explosionproof hole are installed.Negative pole and electrolyte are filled in upper base (air electrode) and go to the bottom in the formed space, must guarantee that negative pole or electrolyte closely contact with upper base by barrier film, with the reduction internal resistance of cell.Air electrode is as the upper base of air cell, can slow down negative pole, the electrolyte pressure to air electrode, plays the effect that prolongs life of air electrode.
Air electrode is the upper base of air cell and goes to the bottom that the side is a housing, and housing is processed by macromolecule polymer material.At upper base or side negative pole expansion cushion chamber is installed, steam vent or explosionproof hole is housed at the top of cushion chamber.The air cell internal structure is that the air cell upper base is identical with air electrode.The hateful big air cell power output of this structure is effectively utilized limited space, improves the negative pole utilance.
Air electrode be air cell upper base, go to the bottom and one of them side (or several side), carry out different combinations according to the requirement of air cell power output, its internal structure and steam vent can be determined with reference to above-mentioned several forms.
The negative material of air electrode can adopt metals such as zinc, magnesium, aluminium, iron.Negative pole structure specifically can be divided into tabular negative pole, platinum shape negative pole, powder negative pole, the tabular negative pole of powder, graininess negative pole, pasty state powder negative pole.If negative pole adopts powder negative pole, the tabular negative pole of powder, graininess negative pole, pasty state powder negative pole just must insert negative current collector in negative pole, collect the electric current of metal particle output.Tabular negative pole specific area is less, occur polarization easily, but negative pole intensity is better, and the tabular negative pole specific area of powder is bigger, and the output current ability is strong, and utilance is higher, but negative pole intensity is lower.
The electrolyte form can be taked two kinds of forms, and first kind is liquid, is gel state in second.The liquid electrolyte internal resistance is less, be fit to the output high current density and use, but the cell sealing difficulty is bigger, and the gel state electrolyte internal resistance is bigger, is suitable in the output, the low current density occasion uses, and cell sealing is more or less freely, and the battery that is fit to dynamically use uses.
