The present invention provide a kind of bipolar plates for the battery that adds water, including overlap successively metallic anode plate, fold copper
Piece and air cathode, the fold copper piece clip is between metallic anode plate and air cathode.Above-mentioned bipolar plates, on the one hand, fold
Copper sheet can not only conductive, waterproof, its fold passage is also built into air duct, can improve diffusibility of the air in inside battery
Can, and then the discharge performance of raising battery, that is, increased electric current density and the discharge power of battery；On the other hand, the bipolar plates
The quick assembling of battery can be advantageously implemented as the basic module of the battery that adds water.
In further technical scheme, the air cathode includes catalyst, carbon black and binding agent.
In further technical scheme, the catalyst is manganese-based catalyst or noble metal catalyst, the binding agent
For politef or Kynoar.
In further technical scheme, the fold passage on the fold copper sheet is in unidirectional array or crisscross row
Row.
In further technical scheme, the section of the fold copper sheet is curved, or broken line, or continuously trapezoidal.
In further technical scheme, the surface of the fold copper sheet is additionally provided with parting bead laterally or vertically.
In further technical scheme, the parting bead is adhesive tape or resin streak.
Description of the drawings
Fig. 1 is to add water the structural representation of battery.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to this.
One kind proposed by the present invention battery that adds water can be used for various fields, little to pocket lamp, night-light, greatly to electrokinetic cell,
Which suffers from superior performance.The battery that adds water includes 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 include the metallic anode plate 31, pleat for overlapping successively
Wrinkle copper sheet 32 and air cathode 33, fold copper sheet 32 is clipped between metallic anode plate 31 and air cathode 33, and water accepting layer 5 is fitted in
The outside of the air cathode 33 of bipolar plates 3, metallic anode plate 31 is made up of magnesium alloy plate or aluminium alloy plate.
Specifically, outer fold copper sheet 6 that the battery that adds water includes to be arranged in order, outer air cathode 7, outer water accepting layer 8, Duo Ge electricity
Pool unit and outer metallic anode plate 4, multiple battery unit parallel arranged sandwiched are in outer water accepting layer 8 and outer metallic anode plate 4
Between, water accepting layer 5 is accompanied between adjacent two bipolar plates 3, near the water accepting layer 5 of the outermost battery unit of outer metallic anode plate 4
Fit 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.In 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 adding water battery, its advantage is：On the one hand, fold copper sheet
32 can not only conductive, waterproof, its fold passage is also built into air duct, can improve diffusibility of the air in inside battery
Can, and then the discharge performance of raising battery, that is, increased electric current density and the discharge power of battery；On the other hand, the bipolar plates 3
The quick assembling of battery can be advantageously implemented as the basic module of the battery that adds water.
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 also cheap；Metallic anode plate 31 is made up of magnesium alloy plate or aluminium alloy plate, and Performance comparision is stable, is not in the safety of spark
Hidden danger.
It should be noted that the fold passage on fold copper sheet 32 is in unidirectional array, it is horizontal, vertical or oblique all right,
In a preferred embodiment, the fold passage on fold copper sheet 32 can which not only adds air with criss-cross arrangement
Diffusion admittance, also suitably increased the intensity of fold copper sheet 32, and bipolar plates 3 can be prevented to be driven plain in assembling process.Separately
Outward, the section of fold copper sheet 32 can be curved, or broken line, or continuously trapezoidal.In another preferred embodiment, fold
The surface of copper sheet 32 is additionally provided with parting bead laterally or vertically, and parting bead is adhesive tape or resin streak, can so prevent fold copper sheet 32
The air duct obstruction for causing after being driven plain.
As a kind of preferred embodiment, one layer of microvillus in the plate face of metallic anode plate 31, are adhered to, microvilluss are located to be inhaled
Between water layer 5 and metallic anode plate 31, Microvillares water-holding capacity is stronger, improves the endurance of water suction battery；Furthermore, micro-
Fine hair can also absorb the deformation that cell reaction brings, and slow down the deformation of battery.
In addition, above-mentioned bipolar plates 3 and the battery that adds water, another important function of fold copper sheet 32 is that fold copper sheet 32 can
So that a certain degree of deformation is absorbed 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
The restriction present invention, all technical schemes for being obtained by the way of equivalent or equivalent transformation, all fall within this in any form
