Cell panel, cell panel is provided with negative electrode and anode, and negative electrode is made up of aluminium alloy plate material or magnesium alloy plate material, negative electrode and anode it
Between be provided with absorbent paper, anode is close to the another side of absorbent paper and is posted Copper Foil.This battery gets wet and can work, and does not haves spark,
But the electric current density of this battery is limited, it is difficult to carry out high power discharge, this just greatly limit the range of application of this battery.
Summary of the invention
For the problem of above-mentioned existence, the invention provides a kind of bipolar plates for adding water battery, considerably increase electricity
The electric current density in pond and discharge power.
A kind of bipolar plates for adding water battery that the present invention provides, including the metallic anode plate overlapped successively, fold steel
Sheet and air cathode, described fold steel piece clip is between metallic anode plate and air cathode, and described fold steel disc is towards metal sun
Conductive copper adhesive plaster it is stained with on the face of pole plate.Above-mentioned bipolar plates, on the one hand, fold steel disc can not only conduct electricity, waterproof, its fold passage
Also it is built into air duct, it is possible to improve the air diffusion at inside battery, and then the discharge performance of raising battery, i.e. increase
Electric current density and the discharge power of battery are added；On the other hand, this bipolar plates can be as adding the basic module of water battery, favorably
Assembling in realizing the quick of battery, conductive copper adhesive plaster is possible to prevent fold steel disc portion overreaction to bore a hole.
In further technical scheme, described air cathode includes catalyst, carbon black and binding agent.
In further technical scheme, described catalyst is manganese-based catalyst or noble metal catalyst, described binding agent
For politef or Kynoar.
In further technical scheme, the fold passage on described fold steel disc is unidirectional array or crisscross row
Row.
In further technical scheme, the section of described fold steel disc is curved, or broken line, or the most trapezoidal.
In further technical scheme, the surface of described fold steel disc is additionally provided with parting bead laterally or vertically.
In further technical scheme, described parting bead is adhesive tape or resin streak.
Accompanying drawing explanation
Fig. 1 is the structural representation adding water battery.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to this.
The one that the present invention proposes adds water battery and can be used for various field, little to pocket lamp, night-light, greatly to electrokinetic cell,
It suffers from superior performance.This add water battery include positive pole 2, negative pole 1 and between positive pole 2 and negative pole 1 at least one
Individual battery unit, battery unit includes water accepting layer 5 and bipolar plates 3, and bipolar plates 3 includes metallic anode plate 31, the pleat overlapped successively
Wrinkle steel disc 32 and air cathode 33, fold steel disc 32 is clipped between metallic anode plate 31 and air cathode 33, fold steel disc 32
Being stained with conductive copper adhesive plaster on the face of metallic anode plate 31, water accepting layer 5 is fitted in the outside of the air cathode 33 of bipolar plates 3, gold
Belonging to positive plate 31 to be made up of magnesium alloy plate or aluminium alloy plate, conductive copper adhesive plaster is possible to prevent fold steel disc portion overreaction
And bore a hole.
Specifically, outer fold copper sheet 6 that water battery includes being arranged in order, outer air negative electrode 7, outer water accepting layer 8, Duo Ge electricity are added
Pool unit and outer metallic anode plate 4, multiple battery unit parallel arranged are also folded in outer water accepting layer 8 and outer metallic anode plate 4
Between, accompany water accepting layer 5 between adjacent two bipolar plates 3, near the water accepting layer 5 of the outermost battery unit of outer metallic anode plate 4
Fitting with outer metallic anode plate 4, positive pole 2 is connected with outer fold copper sheet 6, and negative pole 1 is connected with outer metallic anode plate 4.It addition, air
Negative electrode 33 includes catalyst, carbon black and binding agent, and catalyst is manganese-based catalyst or noble metal catalyst, and binding agent is poly-tetrachloro
Ethylene or Kynoar.Therefore, no matter being bipolar plates 3 or add water battery, on the one hand it have the beneficial effect that, fold steel disc
32 can not only conduct electricity, waterproof, its fold passage is also built into air duct, it is possible to improve the air diffusibility at inside battery
Can, and then the discharge performance of raising battery, i.e. add electric current density and the discharge power of battery；On the other hand, this bipolar plates 3
The quick assembling of battery as adding the basic module of water battery, can be advantageously implemented.
In a preferred embodiment, water accepting layer 5 is absorbent paper or sponge, draws materials conveniently, and water suction and water-holding capacity are good, valency
Lattice are the most cheap；Metallic anode plate 31 is made up of magnesium alloy plate or aluminium alloy plate, and Performance comparision is stable, does not haves the safety of spark
Hidden danger.
It is it should be noted that the fold passage on fold steel disc 32 is unidirectional array, horizontal, vertical or oblique all right,
In a preferred embodiment, the fold passage on fold steel disc 32 can which not only adds air with criss-cross arrangement
Diffusion admittance, the most suitably adds the intensity of fold steel disc 32, is possible to prevent bipolar plates 3 to be driven plain during assembling.Separately
Outward, the section of fold steel disc 32 can be curved, or broken line, or the most trapezoidal.In another preferred embodiment, fold
The surface of steel disc 32 is additionally provided with parting bead laterally or vertically, and parting bead is adhesive tape or resin streak, is so possible to prevent fold steel disc 32
The air duct caused after being driven plain blocks.
As a kind of preferred embodiment, the plate face of metallic anode plate 31 adhering to one layer of microvillus, microvillus is positioned at suction
Between water layer 5 and metallic anode plate 31, Microvillares water-holding capacity is relatively strong, improves the flying power of water suction battery；Furthermore, micro-
Fine hair can also absorb the deformation that cell reaction brings, and slows down the deformation of battery.
It addition, above-mentioned bipolar plates 3 and add water battery, another important function of fold steel disc 32 is that fold steel disc 32 can
To absorb a certain degree of deformation during cell reaction, prevent the expansion of battery overall volume.
The foregoing describe ultimate principle and its structure of the present invention.Those skilled in the art it should be appreciated that embodiment not
Limit the present invention, the technical scheme that the mode of all employing equivalents or equivalent transformation is obtained in any form, all fall within this
In the protection domain of invention.
